District of Columbia Permit Practice Test — DMV Written Test

Free 10-question District of Columbia permit practice test, then 40-question practice tests, each question cited to the DC Driver Manual.

The exam

This practice test is 40 questions, and 32 correct is a pass. Everything on it comes out of DC Driver Manual. Officially it is the knowledge test; most people call it the written test, or the permit test.

District of Columbia does not publish how many questions its knowledge test asks, or the score that passes it. This practice test asks 40 and passes at 32.

How this works

Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.

You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.

Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.

Ask a question about District of Columbia road law

Easier than searching the manual: ask in your own words — how far from a fire hydrant you may park, when you must stop for a school bus — and the answer comes from DC Driver Manual or District of Columbia’s code, with the page or the section it is in. When neither says, the answer says so rather than guess. Or tick Nationwide and compare every state on one question.

Questions from the District of Columbia test

Where does the District's manual say it matters most to allow for the mistakes of others?

Near intersections and crosswalks. Most crashes need two people to go wrong; the driver who expects the other one to slip is the one who has room to stop. DC Driver Manual, p.4: “Safe driving requires the ability to foresee danger and make allowances for the mistakes of others, especially when approaching intersections and crosswalks.”

Besides being healthy and emotionally fit, what does the manual say a driver is responsible for?

Keeping the vehicle in good shape. A sick or furious driver, or a car with bad brakes, puts everyone nearby at risk, not just the person behind the wheel. DC Driver Manual, p.4: “drivers have a responsibility to be generally healthy, emotionally fit to drive, and ensure any vehicle being used is in good operating condition for their own safety and the safety of others.”

What are the two major risk factors the District's manual says threaten driver and public safety?

Distracted and impaired driving. Knowing the two biggest dangers tells you where to put your effort: eyes and mind on the road, and never driving drunk, drugged or exhausted. DC Driver Manual, p.4: “Two major risk factors that threaten driver and public safety are Distracted and Impaired Driving.”

How does the District's manual describe distracted driving?

Anything pulling focus off driving. A distraction does not have to be a phone; anything that pulls your mind off the road, even for a moment, counts. DC Driver Manual, p.4: “it can be described as any activity that could divert a person’s attention away from the primary task of driving.”

Which of these does the manual list as a common driving distraction?

Using the navigation system. Everyday habits like setting the GPS or chatting feel harmless, which is exactly why drivers let them steal their attention. DC Driver Manual, p.5: “Using the navigation system Adjusting the radio, CD player, or MP3 player Talking to passengers”

Along with alcohol and drugs, what else does the manual count as impaired driving?

Driving while sleepy. Being very tired slows you down much like a drink does, so the manual counts it as impairment too. DC Driver Manual, p.5: “Operating a motor vehicle while you are affected by alcohol, legal or illicit drugs, and sleepiness are all part of what is known as Impaired Driving.”

Which of these does the manual list as a factor affecting your blood alcohol concentration?

How quickly you drink. Two people can drink the same amount and end up at very different levels, so you cannot judge your BAC by counting drinks. DC Driver Manual, p.5: “Impacts of Alcohol – factors affecting blood alcohol concentration (BAC) levels o How quickly you drink o Body weight o Food in the stomach o Alcohol concentration o Medications o Fatigue, stress and mood”

How does sleep deprivation compare with alcohol in its effect on driving?

As bad or worse. Drivers who would never drink and drive still get behind the wheel exhausted, not realizing it can be just as dangerous. DC Driver Manual, p.5: “Many people do not realize sleep deprivation affects driving just as much, and sometimes more, than alcohol.”

What effect does rolling down the windows or turning up the music have on a sleepy driver's alertness?

Little to no effect. These tricks make a tired driver feel awake for a minute while the drowsiness that causes the crash stays put. DC Driver Manual, p.5: “Studies have proven “rolling down the windows or turning up the music” have little to no effect on alertness,”

What does coffee or another caffeine supplement do for a drowsy driver?

A short-term energy boost. Caffeine wears off, and when it does the sleepiness comes back, often suddenly and at speed. DC Driver Manual, p.5: “coffee or other caffeine supplements provide only a short-term energy boost.”

What is the best way to prevent drowsy driving?

Getting adequate sleep. Nothing you do in the car replaces the sleep your brain is missing. DC Driver Manual, p.5: “Getting adequate “sleep” is the best way to prevent drowsy driving.”

What should you do if you become sleepy while driving?

Pull off to a safe location. A driver who nods off for two seconds can drift into oncoming traffic; stopping somewhere safe is the sure fix. DC Driver Manual, p.6: “Drivers should make it a daily priority to get sufficient sleep, refuse to drive when sleep-deprived, and pull off the road to a safe location when sleepy.”

Under the manual's expanded definition, which road users count as drivers?

Any vehicle not on rails. If you think only car drivers count, you stop watching for the cyclist or bus that shares the road with you. DC Driver Manual, p.6: “the definition must be expanded to include, bicycles, buses, motorcycles, light trucks, commercial vehicles, and essentially any vehicle that does not operate on rails.”

Which of these is a pedestrian, as the District's manual defines one?

A person in a wheelchair. A person in a wheelchair or pushing a stroller across the street is owed the same care as someone on foot. DC Driver Manual, p.7: “A pedestrian can be defined as any person who may travel by foot, wheelchair, stroller, walking, running or jogging.”

Why does the manual say children are at greater risk in traffic crashes?

Small size, little traffic sense. Small children are hard to see over a hood and may dart out without knowing the rules, so slow down wherever they could be. DC Driver Manual, p.7: “due to their small size and lack of experience with traffic rules, children are at greater risk of injury or death from traffic crashes.”

Where does the manual say it is safest for a pedestrian to walk?

On a sidewalk. A walker who crosses where drivers expect people, and makes sure they are seen, gives drivers the best chance to stop. DC Driver Manual, p.7: “Cross the street at crosswalks and intersections • Increase your visibility and make sure drivers see you • It’s safest to walk on a sidewalk”

What should a bicyclist do at a red light or stop sign?

Stop, like any vehicle. A cyclist who rolls through a red light meets cross traffic whose drivers have no reason to expect them. DC Driver Manual, p.7: “Bicycles have the similar roadway rights as vehicles, and to ensure safety, bicyclists should:”

What does the District's manual say bicyclists should always wear?

A helmet. In a fall or a crash, a cyclist's head often hits the pavement or the car, and a helmet is what protects it. DC Driver Manual, p.7: “Stop at red lights and stop signs Always wear a helmet”

Where does the manual tell bicyclists not to ride?

On sidewalks downtown. Downtown sidewalks are crowded with people on foot, and a bike moving among them can knock someone down. DC Driver Manual, p.7: “Watch for opening doors when passing cars Do not ride on sidewalks in downtown areas”

Who must have a driver license in the District of Columbia?

Any driver on public roads. The license is the proof that a driver has shown they know the rules and can handle a car before sharing the road with others. DC Driver Manual, p.13: “Anyone who operates a motor vehicle or motorcycle on public roadways in the District of Columbia is required to have a driver license.”

How soon after moving to the District must you have a DC driver license?

Within 60 days. A new resident who keeps driving on an old state's license for months is outside the District's records and rules. DC Driver Manual, p.13: “You are required to have a DC driver license within 60 days of moving to the District of Columbia.”

What is the minimum age for a DC driver license, as the manual's list of requirements states it?

17 years old. The year between permit and license is time spent practicing with an adult before driving on your own. DC Driver Manual, p.13: “Are at least 17 years old (learner permit at age 16);”

Which tests must you pass to get a DC driver license?

Knowledge, road test and vision. Each test checks something different: what you know, what you can do at the wheel, and whether you can see well enough to do it. DC Driver Manual, p.13: “Have successfully completed the knowledge test, skills road test, and vision screening;”

Below what age do you need a parent's or guardian's consent to get a DC license or permit?

Under age 18. A parent signing off means an adult who knows the teen has agreed to back up their practice and their driving. DC Driver Manual, p.13: “Have parental/guardian consent if under age 18;”

What must you do with a driver license you held before getting a DC license?

Surrender it. One person, one license: two valid licenses would let a driver hide a suspension on one behind the other. DC Driver Manual, p.13: “Surrender any driver license or identification card previously held;”

After how long expired must you pass both the knowledge test and the road test again?

More than 545 days. After a year and a half away, both the rules and the hands-on skill may have slipped, so both are tested again. DC Driver Manual, p.16: “If your DC driver license has been expired for more than 545 days, you will be required to take and pass the knowledge and skills road test examinations.”

What does the District's vision screening check?

Eyesight and peripheral vision. Hazards often come from the side, so side vision matters as much as reading a line of letters. DC Driver Manual, p.16: “This screening determines whether your eyesight and peripheral vision meet the District’s standards to safely operate a motor vehicle.”

What must you do if you fail the DC vision screening?

Submit an eye doctor's report. A screening machine can only flag a problem; an eye doctor decides whether you can see well enough to drive. DC Driver Manual, p.16: “If you fail the vision screening, you are required to submit and Eye Report from your eye care professional.”

If you needed glasses to pass the vision screening, what does the District require?

Wear them whenever you drive. Lenses that let you pass the test do nothing on the road if they stay in your pocket. DC Driver Manual, p.16: “If you need to wear glasses or contact lenses to pass the vision screening, you must wear them when you drive, and your license will show this restriction.”

Which of these is part of the DC road skills test?

Parallel parking. The test checks the everyday skills a new driver needs most in the city, including squeezing into a curbside space. DC Driver Manual, p.16: “The Road Skills driving test will include maneuvers, driving in traffic, your ability to use turn signals, safely controlling the vehicle and parallel parking.”

When is the DC road skills test generally waived?

When converting an out-of-state license. A driver already licensed for the same kind of vehicle has passed a road test once; a second one adds little. DC Driver Manual, p.16: “The Road Skills test is generally waived if you possess a valid out-of-state license for the same class of license and are converting to a DC driver license.”

What must you hold to schedule a DC road skills test appointment?

A valid learner permit. The permit stage is where you practice; the road test checks the result, so it cannot be skipped. DC Driver Manual, p.16: “Road Skills tests are scheduled by appointment only. To schedule a driver license road test appointment with the DMV, you must possess a valid learner permit.”

How early must you arrive for your DC road test appointment?

At least 10 minutes. Arriving late eats into the examiner's schedule and starts your test rushed and nervous. DC Driver Manual, p.17: “Arrive at least 10 minutes before your appointment;”

Which of these meets the DC road test's emergency-control rule for the examiner?

A hand brake between the seats. The examiner needs a way to stop the car if a nervous new driver freezes or makes a mistake. DC Driver Manual, p.17: “Have a hand emergency brake located between the seats.”

Which of these can get your DC road test canceled?

Inclement weather. A test on a dangerous road, or in a car the examiner cannot stop, puts the examiner and everyone nearby at risk. DC Driver Manual, p.18: “There is inclement weather or other circumstances beyond DMV’s control that make the road dangerous;”

Below what age must a new District driver go through the GRAD program?

Under age 21. Young drivers crash far more than experienced ones, so the District lets them build experience in steps before full privileges. DC Driver Manual, p.19: “If you are under the age of 21, you must operate under the Gradual Rearing of Adult Drivers (GRAD) Program.”

How old must the driver supervising a DC learner permit holder be?

21 or older. A grown, fully licensed driver beside you can spot a hazard you miss and talk you through it before it becomes a crash. DC Driver Manual, p.19: “A learner permit allows you to operate a motor vehicle when supervised by another driver who is 21 years or older, has a valid full driver license, and is seated next to you in the passenger front seat.”

What is the minimum age for a DC learner permit?

16 years old. The permit is the first step, and it comes only after you show you know the rules and can see the road. DC Driver Manual, p.19: “To obtain a leaner permit you must be at least 16 years old, pass the knowledge test and vision screening.”

How long is a DC learner permit valid for a US citizen?

2 years. The permit is meant to lead to a license, not to be a way to keep driving with a supervisor forever. DC Driver Manual, p.19: “The learner permit is valid for two years for US Citizens and is non-renewable.”

What is the minimum age for a DC provisional driver license?

16 years, 6 months. The extra half year after the permit gives you time to practice with an adult before you drive alone. DC Driver Manual, p.19: “To obtain a provisional driver license you must be at least 16 years, 6 months old.”

How long must you hold a learner permit before getting a DC provisional license?

At least 6 months. Six months of supervised driving through changing seasons and traffic builds the habits a solo driver needs. DC Driver Manual, p.19: “You must have held a valid learner permit for at least 6 months and have no pointable moving violations.”

How many hours of supervised driving must be certified for a DC provisional license?

At least 40 hours. Hours behind the wheel with an adult are where a new driver meets real traffic, weather and surprises with help beside them. DC Driver Manual, p.19: “You must provide a signed 40 hours Certification of Eligibility for Provisional License form certifying that you have at least 40 hours of driving experience accompanied by a licensed driver(s) who is 21 years or older and who has a valid full license.”

Which test must you pass to move from a learner permit to a provisional license?

The road skills test. The road test is the moment someone other than your supervisor checks that you can drive safely on your own. DC Driver Manual, p.19: “You must take and pass the road skills test.”

How long is a DC provisional license valid?

1 year. Renewing keeps a young driver on the provisional rules until they meet the conditions for the next stage. DC Driver Manual, p.19: “The provisional license is valid for one year and is renewable.”

Before what age may a DC provisional license holder not drive for compensation?

Age 18. Driving for pay means long hours, strangers in the car and pressure to hurry, which a new driver is not ready for. DC Driver Manual, p.19: “Prior to age 18, you are not allowed to operate a vehicle for compensation.”

How long must you hold a DC provisional license before getting a full license?

At least 6 months. Time driving on your own, with the provisional limits still in place, is the last step before the limits come off. DC Driver Manual, p.19: “Once you have held your provisional driver license for at least 6 months you must:”

For how long must a provisional driver be free of pointable moving violations before getting a full license?

12 consecutive months. A full year without tickets is the proof that a young driver is driving safely, not just lucky for a few weeks. DC Driver Manual, p.19: “Have no pointable moving violations for 12 consecutive months;”

How many hours of supervised night driving must be certified for a DC full license?

At least 10 hours. Dark roads hide people and hazards, so a new driver needs practice at night with an adult before driving at night alone. DC Driver Manual, p.19: “Practice night driving for at least 10 hours,”

A new driver who is not in GRAD has met the learner permit requirements. What comes next for a full license?

Passing the road skills test. Adults skip the GRAD steps, but still have to show an examiner they can drive before getting a license. DC Driver Manual, p.19: “If you are not required to participate in the GRAD program, once you have completed all of the requirements for the learner permit you must take and pass the Road Skills test and my then be issued a full driver license.”

A regular DC driver license covers non-commercial vehicles with a GVWR under how many pounds?

26,001 pounds. Heavier vehicles take far longer to stop and turn, so driving them needs a different license and training. DC Driver Manual, p.20: “driver license you may operate vehicles with a gross vehicle weight rating (GVWR) less than 26,001 pounds for non-commercial use, motor-driven cycles, and passenger vans seating up to fifteen (15) passengers.”

Until what time at night may a DC learner permit holder drive?

9:00 pm. Late-night roads have more tired and drunk drivers and less light, which is the worst place for a beginner. DC Driver Manual, p.20: “Learner Permit Must be accompanied by a driver 21 years or older Everyday, 6:00am – 9:00pm”

Which trip lets a GRAD driver drive during restricted hours?

Driving to or from work. The limits are meant to keep teens off the road at night for no reason, not to stop them getting to a job or practice. DC Driver Manual, p.20: “You can operate a motor vehicle during GRAD restricted hours if you are driving to or from work, a school-sponsored activity, religious or an athletic event, or related training session in which you are a participant,”

What may a DC learner permit holder do once they turn 21?

Schedule a road test right away. The GRAD steps exist for young drivers, so at 21 a permit holder moves on to the same road test as any adult. DC Driver Manual, p.21: “At age 21, GRAD drivers are released from the program. During the learner permit stage, once you are age 21, you may immediately schedule a road test appointment.”

May a DC learner permit holder use a phone with a hands-free accessory while driving?

No, not even hands-free. Even a hands-free call pulls a beginner's mind off a task that still takes all of it. DC Driver Manual, p.21: “You may not use a mobile phone or other electronic device (with or without hands free accessories) while driving.”

Besides the supervising driver, who may ride with a DC learner permit holder?

No other passengers. Friends in the car distract a beginner and crowd out the supervisor whose job is to teach. DC Driver Manual, p.21: “You may not drive with other passengers in the vehicle.”

Under 18 with a full license, which vehicle use is allowed in the District?

A passenger car for pleasure. Work driving and bigger vehicles bring pressure and handling a young driver is not ready for yet. DC Driver Manual, p.21: “If you are under 18 years old, you may not operate a motor vehicle other than a passenger vehicle or motorized bicycle used solely for the purposes of pleasure and not for compensation.”

Who is notified of GRAD violations by a driver under 18?

The parent or guardian. A parent who knows about a ticket can help a young driver change habits before the next one turns into a crash. DC Driver Manual, p.22: “If you are under 18, your parent/legal guardian is notified of your GRAD violations.”

What does a pointable moving violation during the DC learner permit stage do?

Extends your wait for a license. Moving up is earned by safe driving, so a ticket resets the clock on proving it. DC Driver Manual, p.22: “Any pointable moving violation for which you admit to, have been found liable for, or convicted of will extend the amount of time you must wait to apply for a provisional license.”

What is the lowest point total that gets a DC learner permit suspended?

8 points. A beginner piling up points is showing unsafe habits early, and the suspension stops them before those habits harden. DC Driver Manual, p.22: “During your learner permit stage, if 8 points or more have been assessed against you or you have violated any GRAD program restrictions, you will be subject to a ninety (90) days suspension of your learner permit and payment of a reinstatement fee.”

How long is a DC provisional license suspended for a first GRAD restriction violation?

30 days. Each repeat shows the lesson did not stick, so the time off the road grows. DC Driver Manual, p.22: “During your provisional license stage, if you violate any GRAD program restrictions, you will be subject to a thirty (30), sixty (60), or ninety (90) days suspension of your provisional license depending whether it is your first, second, third or more violation of GRAD program restrictions.”

How may a fully licensed driver use a cell phone while driving in the District?

Only hands-free. A phone held to your ear takes a hand off the wheel just when you may need both to steer clear of trouble. DC Driver Manual, p.25: “You must be hands-free while driving with a cellular phone in the District of Columbia”

Within how many days must a District resident report a change of address to the DMV?

60 days. Tickets, renewal notices and suspension letters go to the address on file, so an old address means you miss them. DC Driver Manual, p.25: “Residents are required to update change of address with the Department of Motor Vehicles within sixty (60) days”

How long must you keep insurance on a vehicle registered in the District?

As long as it is registered. A registered car can be on the road any day, and a crash with no insurance leaves the injured person with nobody to pay. DC Driver Manual, p.25: “Insurance must be maintained as long as the vehicle is registered.”

What must you show a police officer who stops you while driving in the District?

License, registration and insurance. The officer has to know who you are, that the car is lawfully yours to drive, and that it is covered if something happens. DC Driver Manual, p.25: “you will be responsible for providing your valid driver license, vehicle registration and proof of insurance.”

Which moving violations can put points on a District driving record?

Ones in DC or other states. Without this, a driver could rack up tickets just across the state line and keep a clean record at home. DC Driver Manual, p.25: “Drivers receive point for certain moving violations, whether the violations occur in the District of Columbia or in other states.”

How long do points stay active on a District driving record?

2 years. Old mistakes fall away so a driver who has cleaned up is not judged forever, but recent ones still count. DC Driver Manual, p.25: “Points will stay active on your driving record for two years”

What may earn a District driver a Good Point?

A full calendar year with no pointable violations. A reward for a clean year gives drivers a reason to keep driving carefully, not just to avoid trouble. DC Driver Manual, p.25: “If you maintain a valid DC driver license for a full calendar year without obtaining pointable moving violations, you may be eligible to receive a Good Point on your driving record”

At what point total is a District driver license first suspended?

10 points. A driver who keeps breaking traffic laws is a danger to everyone, so a pause off the road comes before anything harsher. DC Driver Manual, p.25: “If you accumulate 10 or 11 points, your DC driver license will be suspended and you will lose your driving privileges for a period of ninety (90) days.”

How many points will get a District driver license revoked?

12 or more. A driver with that many violations has shown over and over that they put others at risk, so the license is taken away, not just paused. DC Driver Manual, p.25: “If you accumulate 12 or more points, your DC driver license will be revoked and you will not be eligible for reinstatement for six months.”

Besides traffic violations, what can get your District license and vehicle suspended?

Not paying child support. Threatening the license gives a parent who will not pay a strong reason to start paying for their child. DC Driver Manual, p.25: “Your driver license and vehicle can be suspended for failure to pay child support”

What does the District forbid while you drive, regarding the rear-view mirror?

Anything hanging from it. An air freshener or charm swinging under the mirror can hide a person or car right where you are looking. DC Driver Manual, p.26: “Having something attached to or hanging from the rear view mirror while driving is against the regulations of the District of Columbia”

Which of these does the District manual list as part of being in shape to drive?

Being emotionally fit. Driving takes your eyes, your attention and your temper all at once, and any one of them failing can cause a crash. DC Driver Manual, p.27: “The motorist’ ability to drive safely depends on the ability to see clearly, not being overly tired, not driving while on drugs, being generally healthy, and being emotionally fit to drive.”

What is driving a motor vehicle in the District, by law?

A privilege. Because driving is earned, the District can take it away from someone who drives unsafely. DC Driver Manual, p.27: “Driving a motor vehicle in the District of Columbia is a privilege and not a right.”

What can happen if you knowingly possess a false driver license in the District?

A fine or prison. A fake license lets someone drive or buy things they are not allowed to, and hides who they really are. DC Driver Manual, p.27: “or knowingly possess a false or fraudulent identification card, driver license, or permit, you may be subject to a fine or imprisonment.”

What are traffic laws intended to do?

Prevent crashes. Everyone on the road follows the same rules, so each driver can guess what the others will do next. DC Driver Manual, p.27: “Traffic laws are intended to prevent crashes and keep traffic moving.”

Which is one of the four major components of driving?

Thinking and deciding. Most crashes start with one of these steps skipped, like seeing a hazard but never deciding what to do about it. DC Driver Manual, p.28: “Four Major Components of Driving”

Whose directions must you obey in an emergency situation, besides the police?

Firefighters. At a fire or crash scene, firefighters know where hoses, victims and danger are, and ignoring them puts people at risk. DC Driver Manual, p.28: “You have a responsibility to obey road sign, traffic signals, lane markings, orders of police officers, and in emergency situation the direction of firefighters.”

A police officer waves you through a red light. What should you do?

Follow the officer. When a signal breaks or a crash blocks a road, the officer can see what the light cannot, and the instructions keep traffic moving safely. DC Driver Manual, p.29: “You must obey the instructions of a police officer even though they may be contrary to laws, signs, signals, and markings.”

Aggressive driving is a form of which offense?

Reckless driving. Aggressive moves like weaving and tailgating show the same disregard for others' safety that the law punishes as reckless. DC Driver Manual, p.29: “Aggressive driving is a form of reckless driving.”

What does the District manual advise if you are running late?

Just be late. Most aggressive driving comes from feeling rushed, and leaving early or accepting a late arrival takes that pressure off. DC Driver Manual, p.30: “Just be late”

What makes driving reckless under District law?

Willful disregard for safety. Choosing to ignore other people's safety is what turns a careless mistake into a more serious crime. DC Driver Manual, p.30: “With a willful disregard for the safety of people or property; or”

Where in the District may you take part in a drag race?

On no public road. Racing on public roads puts high speed right next to people and cars that never agreed to the risk. DC Driver Manual, p.30: “You must not engage in any vehicle race, speed exhibition, or speed contest including those commonly known as drag races on any public street, road, or highway.”

How long must you stay at the scene of a crash you are involved in?

Until you aid and identify. Leaving a crash can leave a hurt person without help, and a car left in the lane can cause a second crash. DC Driver Manual, p.30: “As close to the scene as possible until you have aided any injured person and identified yourself.”

You hit and injure a dog with your car. Whom should you notify right away?

The police. A hurt pet left in the road can die or cause another crash, and the police know who can come and treat it. DC Driver Manual, p.31: “If you should strike and injure a domestic animal with a motor vehicle, you should immediately notify the police department having jurisdiction in the area where the crash occurred.”

Which check does the District manual list before you drive?

Brake lights and signals. A flat tire, a leak or a dead brake light is far easier to deal with in the driveway than in traffic. DC Driver Manual, p.32: “Check vehicle brake lights and signals before you drive”

When should you decide to make a turn?

Well before the turning point. A sudden swerve or stop for a turn you almost missed gives the drivers around you no warning. DC Driver Manual, p.32: “Make up your mind well in advance of reaching the turning point.”

What is the safe way to check behind you when backing?

Turn your head and use both mirrors. The inside mirror cannot show a small child or a tricycle right behind the bumper. DC Driver Manual, p.32: “In most conditions, it is safe to back up provided you turn your head and look back out the rear window and check both side view mirrors.”

When should you sound your horn?

To warn in an emergency. Honking instead of braking leaves you still rolling toward the danger you are trying to warn about. DC Driver Manual, p.33: “Sound your horn only to warn a pedestrian, cyclist or the driver of another vehicle in the event of an emergency.”

Before backing out of a driveway, what may you need to do?

Get out and look. A small child or a toy sitting behind the car is often too low to see from the driver's seat. DC Driver Manual, p.33: “When you must back out, be sure to look behind your car first.”

When should you add hand signals to your turn signals?

When the sun is bright. In glare or behind a close truck your blinker can be invisible, so your arm is the only signal others see. DC Driver Manual, p.33: “Use hand signals in addition to your turn signals when the sun is shining brightly and when vehicles immediately behind you obscure your turn signal.”

What should you never let passengers or parcels do while you drive?

Crowd you. A packed front seat can pin your arms or hide a car in the next lane. DC Driver Manual, p.33: “Never let passengers or parcels crowd you while you are driving.”

Where should you put loose objects in your car?

In the trunk. In a sudden stop, a phone or bottle keeps flying forward and can hit someone in the head. DC Driver Manual, p.33: “Put loose objects in the trunk or on the floor, since even objects on seats can fly up and strike you or another passenger.”

What should you watch for when driving past parked cars?

Children stepping out. A child darting out from between parked cars is hidden until the last moment. DC Driver Manual, p.34: “When driving pass parked cars watch out for opening car doors, pedestrians (especially children) stepping out or running from between cars and bicyclists.”

Which of these is a place where you must slow down?

The crest of a hill. You cannot see what is past a hilltop or around a curve, so you need time to stop for whatever is there. DC Driver Manual, p.34: “Coming to an intersection, railroad grade crossing, curve, or the crest of a hill;”

How does wet pavement change your stopping distance?

It gets longer. Water between the tires and the road means less grip, so the car slides farther before it stops. DC Driver Manual, p.34: “When the road is wet, it is much more difficult to hold the road on curves and it takes a longer distance to stop.”

Up to what speed do most tires with tread wipe a wet road like a windshield wiper?

35 mph. Above a certain speed the tread cannot push the water away fast enough, and the tire loses its grip on the road. DC Driver Manual, p.34: “At speeds up to 35 miles per hour, most tires with tread will “wipe” the road surface the way a windshield wiper cleans the windshield.”

What should you do if you see a flooded road ahead?

Turn back and reroute. Water can hide dips or a washed-out road surface, so a road that looks shallow may not be there at all. DC Driver Manual, p.35: “If you see a flooded roadway ahead, turn around and find another route to get to your destination.”

What causes most rear-end collisions?

Following too closely. If the car ahead stops suddenly, the space in front of you is the only thing that keeps you from hitting it. DC Driver Manual, p.35: “Most rear-end collisions are caused by following too closely.”

Which of these affects your stopping distance, according to the manual?

Condition of the brakes. Knowing what lengthens a stop helps you pick a speed that lets you stop in time. DC Driver Manual, p.36: “your actual stopping distance will depend upon many factors, including:”

At 55 mph, about how far does your car travel while you look away for three to four seconds?

The length of a football field. A quick look at something in the car feels short, but the car keeps moving the whole time with nobody watching where it goes. DC Driver Manual, p.37: “If you take your eyes off the road for three to four seconds, your vehicle travels the length of a football field if you are going 55 miles per hour.”

Before you drive a car you are not used to, what should you do first?

Adjust mirrors and seat, find controls. In a borrowed car you end up hunting for the wiper switch or fixing a mirror while already moving, with your eyes off the road. DC Driver Manual, p.37: “Driving an unfamiliar vehicle without first adjusting the mirrors and seat, selecting entertainment options and locating the lights, turn signals and windshield wipers”

When may a driver in the District text while driving?

Not while driving. Typing a message takes your eyes, your hands and your mind off the road at the same time. DC Driver Manual, p.39: “Remember, texting while driving is never allowed!”

You are very angry after an argument. What should you do before driving?

Calm down or let someone else drive. An angry driver takes risks and reacts to other drivers instead of watching the road. DC Driver Manual, p.39: “If you are upset or angry, take some time to calm down before driving, or let someone else drive.”

When should you secure passengers and loose items in the car?

Before the car moves. A loose pet or a sliding box will pull your attention away the moment the car starts moving. DC Driver Manual, p.39: “Secure everyone and everything before putting the vehicle into motion”

What causes highway hypnosis?

Monotony on a long drive. The same sounds and the same view for hours lull your brain until you stop noticing the road. DC Driver Manual, p.38: “Being unaware of what is happening is known as “highway hypnosis”. It is caused by monotony”

What should you do at the first signs of drowsiness?

Do something positive about it. Willpower alone does not keep a sleepy driver awake, so waiting it out only lets it get worse. DC Driver Manual, p.38: “At first signs of drowsiness, do something positive. Don’t just sit there and try to fight it.”

Which is a danger sign of a drowsy driver?

Not remembering the last miles. These signs mean your brain has already been dozing while the car kept going. DC Driver Manual, p.39: “You don’t remember driving the last few miles”

Which of these is one of the biggest culprits in road rage?

Unsafe lane changing. These are the moves that make other drivers angry and turn a slow commute into a fight. DC Driver Manual, p.40: “The biggest culprits include:”

Which simple rule helps reduce road rage?

Allow extra travel time. A driver running late gets angry at every slow car, while a driver with time to spare can stay calm. DC Driver Manual, p.41: “Always allow extra travel time”

How should you deal with glare from oncoming headlights?

Glance from road edge to ahead. Bright lights shrink your pupils, and your eyes take time to readjust, so looking straight at them leaves you half-blind. DC Driver Manual, p.42: “To avoid the glare from oncoming headlights, glance back and forth between the side of the road and straight ahead.”

How fast should you drive at night?

Slow enough to stop in sight. If something appears at the edge of your headlights, you need to be able to stop before you reach it. DC Driver Manual, p.42: “Keeping your speed low enough to be able to stop within the distance you can see ahead”

Which of these makes night driving more dangerous?

Wearing sunglasses. Dark lenses cut the little light you have at night and hide people and objects on the road. DC Driver Manual, p.43: “Do not wear sunglasses at night”

Which does the most to improve traction and stopping on ice and snow?

Tire chains. Chains bite into ice and snow where rubber alone slips. DC Driver Manual, p.43: “Chains do the most to improve traction and stopping on ice and in snow.”

When must you have chains, snow tires or radial tires on a snow emergency route?

When a snow emergency is declared. Cars without grip get stuck on the main routes and block plows and emergency vehicles. DC Driver Manual, p.44: “Chains, snow tires or radial tires must be used on designated snow emergency routes when a snow emergency is declared”

How should you find out how well you can stop on a snowy road?

Test your brakes gently. You cannot see how slick the road is, so a gentle test tells you how much room you need before you need it. DC Driver Manual, p.44: “Start out very slowly. Then test your brakes gently to find out how well you can stop.”

What does the manual suggest carrying for traction on snow and ice?

Kitty litter or sand. If you get stuck or stranded in snow, the kit helps you dig out, get grip and stay warm until help comes. DC Driver Manual, p.44: “Keep an emergency kit in your vehicle.”

What is a completely safe speed on ice and snow?

There is no such speed. Ice can be anywhere on a winter road, so even a slow car can lose grip. DC Driver Manual, p.44: “There is no such thing as a “completely safe” speed on ice and snow.”

On a car without anti-lock brakes, how should you brake to avoid a skid?

Pump the pedal. Locked wheels slide wherever the car is headed and no longer answer the steering wheel. DC Driver Manual, p.45: “Do not brake strongly and lock the wheels. If the wheels do not turn, you don’t have control over the vehicle.”

How should you press the pedals to avoid a skid?

Gently, as if on an egg. Gentle pedal work keeps the tires gripping, while a sudden push breaks them loose. DC Driver Manual, p.45: “Avoid abrupt changes in speed or direction. Drive as though you have an egg between your foot and the gas or brake pedal.”

On which surface should you be most cautious on a curve?

On an icy road. Curves are where tires slip, and each step from wet to snow to ice gives them less grip. DC Driver Manual, p.45: “Be more concerned about curves in wet weather, even more cautious on snow and most cautious on ice.”

Under 'Recovery From a Skid', what does the manual tell you to do with the brakes?

Do not brake. Braking in a skid locks the wheels and keeps the car sliding instead of letting it grip again. DC Driver Manual, p.46: “Don’t panic and do not brake”

Driving in fog, you see taillights ahead. What should you do?

Slow down even more. Fog hides how close other cars are, and lights ahead mean a car you may reach sooner than you think. DC Driver Manual, p.46: “Reduce your normal driving speed. Reduce speed even more when you see headlights or taillights ahead.”

Another driver's turn signal is flashing. What should you assume?

They may not turn. Signals get left on by mistake, and a driver who pulls out because a car was 'turning' gets hit when it keeps coming straight. DC Driver Manual, p.49: “For example, if the person's turn signal is flashing, don't assume the driver will make a turn.”

What should you constantly be thinking of as you drive?

An escape route. When a car swerves into you there is no time to look around; knowing where you could go has to happen before. DC Driver Manual, p.49: “You should constantly be thinking of an "escape route" as you drive.”

You notice flashing red or yellow lights on a vehicle ahead. What should you look for?

Objects or people on the road. Flashing lights often mean a breakdown, a crash or someone stopped, so a person may be standing in the road. DC Driver Manual, p.49: “For example, if you notice flashing red or yellow lights on a vehicle ahead, you should look for objects or people on the road.”

A crash seems certain. How should you try to hit, if you cannot avoid it?

At an angle. A head-on hit stops the car all at once, while a glancing blow at an angle spreads the force out and is easier to survive. DC Driver Manual, p.49: “Do anything to keep from hitting another vehicle or object head-on; try to hit at an angle.”

What is the most common kind of motor vehicle crash?

A rear-end collision. Knowing the most common crash is a rear-end one tells you why the car behind you deserves as much attention as the one ahead. DC Driver Manual, p.49: “Rear-end collisions are the most common kind of motor vehicle crashes.”

What is the acceleration lane for when entering an interstate?

Reaching the speed of traffic. Merging slowly into fast traffic forces drivers to brake hard or swerve, so you need the lane to build speed first. DC Driver Manual, p.50: “The entrance ramp gets you going in the desired direction and the acceleration lane gives you the opportunity to get up to the speed of traffic.”

The exit is on the right. When should you move into the right lane?

Well before the exit. Cutting across lanes at the last moment at highway speed is how drivers sideswipe cars they never saw. DC Driver Manual, p.50: “Get into the right lane well before reaching the exit, if the exit is on the right side of the highway.”

On an interstate in the District, where should most of your passing be done?

On the left. With slow traffic kept to the right, the left lane stays clear for passing and drivers know where to expect it. DC Driver Manual, p.51: “It is legal in the District of Columbia to pass on the left or on the right, but slow moving vehicles must stay in the right lane.”

What sign marks each road approaching a roundabout?

A yield sign. The yield sign tells you the cars already circling go first, so you do not pull out in front of them. DC Driver Manual, p.51: “Each road approaching the roundabout is marked with a yield sign and may also have yield line markings on the pavement.”

You plan to turn right at a roundabout. Where should you be as you enter?

To the right. Being in the right lane lets you leave at the first exit without crossing anyone still going around. DC Driver Manual, p.51: “If you plan to turn right, stay to the right as you enter the roundabout.”

Entering a roundabout, which vehicles must you yield to?

Vehicles already in it. Cars in the circle cannot stop for you without being hit from behind, so the gap is yours to wait for. DC Driver Manual, p.51: “You also must yield to any vehicles already in the roundabout.”

Which signal should you use to show you are leaving a roundabout?

Your right turn signal. The right signal tells drivers waiting to enter that you are leaving, so they know the space is about to open. DC Driver Manual, p.51: “While inside the roundabout, stay in your lane until you are ready to exit.”

In a roundabout, what should you do about trucks and buses?

Do not overtake them. A truck swinging wide needs the space beside it, so a car trying to pass it there gets squeezed or hit. DC Driver Manual, p.52: “Do not overtake large vehicles.”

When may you stop on the shoulder of a highway?

In an emergency. A car stopped in a travel lane is something fast traffic does not expect, and it gets hit from behind. DC Driver Manual, p.53: “Stopping on the traveled portion of the highway is prohibited.”

When may you back up on a highway?

Under no circumstances. Drivers behind you on a highway are moving forward fast and do not expect a car coming at them in reverse. DC Driver Manual, p.53: “Do not back up on any highway, under any circumstances.”

Your brakes fail and pumping does not help. What should you use next?

The parking brake. Pumping can build back pressure in older brakes, and the parking brake works on its own if the main brakes are gone. DC Driver Manual, p.54: “Try pumping the brake pedal [non-ABS systems].”

What happens when your anti-lock brakes engage?

The pedal vibrates. Drivers who feel the pedal shake think something is broken and let go; knowing it is normal keeps them braking. DC Driver Manual, p.54: “When the ABS engages, you will hear a rumble from the brakes and the brake pedal will vibrate under your foot.”

How should you dry your brakes after driving through deep water?

Drive slowly, braking lightly. Wet brakes can pull to one side or not hold at all, and you want to find that out at low speed. DC Driver Manual, p.54: “After driving through deep water, you should test your brakes.”

Your wipers fail in heavy rain. What should you do?

Look out the window and pull off. You cannot drive blind through rain, so you need just enough sight to get off the road safely. DC Driver Manual, p.54: “If your windshield wipers fail during inclement weather, open the window, put your head out the window, drive your vehicle off the roadway and STOP.”

Your accelerator sticks and slapping it does not free it. What should you shift to?

Neutral. Neutral cuts the engine off from the wheels, so the brakes can stop the car even while the engine races. DC Driver Manual, p.55: “Shift to neutral”

You lose steering but the car stays in its lane. How should you brake?

Gently, after it slows. Hard braking with no steering can swing the car sideways, so a gentle stop keeps it going straight. DC Driver Manual, p.55: “If you suddenly lose steering control, ease up on the accelerator.”

What happens if you turn the ignition to lock while the car is moving?

The steering locks. A locked wheel cannot be turned, so a moving car goes wherever it was pointed, curve or not. DC Driver Manual, p.55: “Never turn your vehicle's ignition to the "lock" position while the vehicle is still in motion.”

Your headlights fail on a lighted highway. What should you do?

Get onto the shoulder quickly. Without headlights other drivers cannot see you well, so the sooner you are out of the lane the better. DC Driver Manual, p.55: “If the highway is lighted, get off the roadway onto the shoulder or other available space as rapidly and safely as possible.”

Your vehicle catches fire. Where should you park it?

In an open area. A burning car next to a building, brush or other cars can spread the fire to them. DC Driver Manual, p.55: “The first step is to get the vehicle off the road and stop.”

A vehicle is coming toward you in your lane. Which way should you move?

To the right. Moving right and making noise and light gets you out of its path and may wake up a driver who has drifted. DC Driver Manual, p.56: “If you see a vehicle coming toward you in your lane, pull to the right, slow down, sound your horn and flash your headlights.”

Your car stalls on the tracks and a train is coming. Which way should you run?

Toward the train. The train throws the wrecked car and its pieces forward, so running toward the train keeps you out of the flying debris. DC Driver Manual, p.57: “If there is a train coming, get out of the vehicle and run along the side of tracks toward the train, to avoid being struck by the debris from the crash.”

Your wheels run off the pavement. How should you use the brakes?

Carefully or not at all. Slamming the brakes with two wheels on loose ground can spin the car or pull it back across the road. DC Driver Manual, p.57: “Do not jam on the brakes. Brake carefully or not at all.”

What do rumble strips warn you about?

Hazards ahead or the road edge. The loud hum wakes up a driver who is drifting or not paying attention before they reach the danger. DC Driver Manual, p.58: “Rumble strips are short sections of corrugated roadway which alert you with the noise your tires make when you drive over them.”

What is the minimum tread depth needed in every major groove on the front wheels?

4/32 of an inch. Worn front tires lose grip first when you steer or brake, especially on wet roads. DC Driver Manual, p.58: “You need at least 4/32-inch tread depth in every major groove on front wheels.”

Which of these is a tire problem you should look for?

Mismatched tire sizes. A bad tire can fail at speed and take your control of the car with it. DC Driver Manual, p.58: “It is dangerous to drive with defective tires.”

What can a bent or cracked rim cause?

A tire to lose pressure. A damaged rim cannot seal against the tire, so it leaks or lets the tire slip off at speed. DC Driver Manual, p.59: “Bent or cracked rims can cause a tire to lose pressure or come off”

Your tire blows out. What should you NOT do?

Apply the brakes. Braking hard on a blown tire yanks the car toward the flat side and can spin it. DC Driver Manual, p.59: “Do not apply the brakes”

Your engine is flooded. What should you do with the gas pedal?

Hold it to the floor. Holding the pedal down lets air clear out the extra fuel, while pumping adds more and makes the flooding worse. DC Driver Manual, p.59: “Press the gas pedal to the floor and hold it down”

Your vehicle is disabled. Where should its wheels be, if possible?

All four off the roadway. A stalled car still partly in the lane is a target, and lights and flares warn drivers in time to go around. DC Driver Manual, p.59: “Get all four wheels off the roadway, if possible”

How should the right-of-way laws weigh against safety?

Safety comes first. Being in the right does not stop a car that is already coming through; insisting on your turn can still get you hit. DC Driver Manual, p.60: “Laws govern the right-of-way, but never put these laws ahead of safety.”

You enter an intersection after another vehicle. Who has the right-of-way?

The vehicle that entered first. The car that got there first is already committed; pulling out after it puts two cars in the same space. DC Driver Manual, p.60: “If you enter the intersection after another vehicle, you must yield the right-ofway”

When does an ambulance have the right-of-way over you?

When it is giving a siren or light signal. Someone is waiting on that ambulance or fire engine, and every second it spends stuck behind traffic is a second lost. DC Driver Manual, p.60: “Authorized emergency vehicles, such as police cars, ambulances and fire engines, have the right-of-way when they are giving a signal, either audible (siren) or visual (flashing light).”

At city street crossings, when do pedestrians lose the general right-of-way?

Where officers or signals control traffic. In a city people cross at every corner, so drivers are the ones expected to stop unless a signal or officer is sorting out who goes. DC Driver Manual, p.61: “All pedestrians have the right of way at street crossings in town and cities, except where traffic officers or traffic control devices control traffic.”

At a busy intersection with pedestrian signals, which signals do drivers obey?

The normal traffic signals. A WALK light faces the walkers, not you; a driver who reads it as a go signal can pull into cross traffic. DC Driver Manual, p.61: “Drivers must obey the normal traffic signals. Pedestrians must obey the WALK and DON’T WALK signals.”

A pedestrian in a crosswalk is on your half of the roadway. What must you do?

Come to a complete stop. A walker in your half of the road is in your path, and one coming fast from the other half will be in it a second later. DC Driver Manual, p.61: “The driver of a vehicle shall come to a complete stop when a pedestrian crossing the roadway in a crosswalk is:”

A pedestrian crosses mid-block, away from any crosswalk. What must you do?

Yield to the pedestrian anyway. Hitting someone who crossed in the wrong place hurts them just as badly, so the driver still has to stop. DC Driver Manual, p.62: “Though the pedestrian does not have the right-of-way in these instances, the driver must always yield to pedestrians in these instances.”

A pedestrian with a guide dog is crossing ahead. What should you do?

Be alert and yield the right-of-way. A person who cannot hear your engine or move quickly may not know you are coming and needs extra time to finish crossing. DC Driver Manual, p.62: “Driver should be especially alert for and yield the right-of-way to pedestrians who are deaf, or have physical disabilities that require the use of canes, crutches, walkers, guide dogs/service animals, wheelchairs, or motorized scooters.”

Compared with cars, what do trucks have?

Longer stopping distances. A truck cannot stop, speed up or turn the way your car does, so a gap that is fine for a car is not fine in front of a truck. DC Driver Manual, p.63: “Trucks have longer stopping and accelerating distances, a wider turning radius, and weigh more.”

How can you let a truck driver know you are passing?

Blink your headlights. A trucker who knows you are coming can stay to the far side of the lane and will not drift into you. DC Driver Manual, p.63: “Let the truck driver know you are passing by blinking your headlights, especially at night.”

How far behind a truck can its rear blind spot reach?

Up to 200 feet. A car sitting in any of those spaces is invisible to the trucker, who may change lanes or brake right into it. DC Driver Manual, p.64: “If you’re following a truck, stay out of its “blind spots”, up to 20 feet in front of the cab, on either side of the tractor-trailer, particularly along the sides of the cab, and up to 200 feet in the rear.”

Why should you dim your headlights when following a truck at night?

They reflect off its mirrors. Those big mirrors throw your high beams straight into the trucker's eyes. DC Driver Manual, p.64: “Bright lights from a vehicle behind will blind the truck driver when they reflect off the truck’s large side mirrors.”

At 60 mph, about how far does a car need to stop?

About 366 feet. The truck needs more road than you do, so cutting in and braking in front of it leaves it nowhere to stop. DC Driver Manual, p.65: “A car traveling 60 miles per hour can stop in about 366 feet.”

Why do trucks make wide turns?

So the rear can clear the corner. A car that slips into the gap on the inside of a turning truck gets crushed by the trailer as it swings around. DC Driver Manual, p.65: “Truck drivers must make wide right or left turns so that the rear of the truck or rear of the tractor or trailer can clear the corner or any other standing obstructions.”

Following or passing a truck in rain, what can its spray do?

Reduce visibility to nearly zero. A sheet of spray from a big rig can blind you for seconds while you are right beside it. DC Driver Manual, p.65: “Splash or spray from a truck’s wheels and trailer can reduce visibility to nearly zero.”

Your exit is coming up and a truck is beside you. What should you do?

Slow down and exit behind it. Diving into the open space in front of a truck takes away the cushion its driver needs to stop. DC Driver Manual, p.65: “Take a moment to slow down and exit behind a truck – it will only take a few extra seconds.”

How far from a stopped school vehicle with flashing red lights must you stop?

At least 20 feet. Children getting on or off may cross in front of or behind the bus, and the gap gives you room to see them. DC Driver Manual, p.66: “When a school vehicle is stopping or has stopped on the roadway, and is operating the alternating flashing red lights, all vehicles must stop at least 20 feet from the front or rear of the school vehicle.”

How may you pass a motorcycle?

From another lane, not within its lane. A rider dodging a pothole may need the whole lane, and squeezing past in the same lane leaves them nowhere to go. DC Driver Manual, p.66: “Allow ample room for the motorcycle when passing and remember it is against the law to overtake or pass a motorcycle within the same lane.”

How does the District treat bicycles on the road?

As vehicles. A cyclist has the same right to the road as you do, so treating them as a nuisance to push past is how people get hurt. DC Driver Manual, p.67: “Bicycles are treated as vehicles in the District of Columbia.”

What should you do as you approach a bicyclist?

Slow down as you near them. A cyclist usually hears you coming already, and a sudden blast can make them wobble right into your path. DC Driver Manual, p.67: “As you approach a bicyclist, slow down.”

What is the minimum clearance when passing a cyclist?

3 feet. A rider may wobble or swerve around debris, and a car passing closer than that clips them or knocks them off balance. DC Driver Manual, p.72: “When passing a cyclist, allow a minimum of three feet clearance.”

A cyclist moves out of the right side of the road into a left turn lane. What is this?

Expected of cyclists. A cyclist moving left into a turn lane is following the rules, so expect it rather than crowding them back to the curb. DC Driver Manual, p.68: “A bicycle should be operated as close to the right side of the road as possible.”

On which side do you pass a stopped streetcar traveling your direction?

The left side. Riders step off the streetcar into the street, and a car passing on the wrong side runs straight through them. DC Driver Manual, p.69: “When passing a stopped street car traveling in the same direction, use extreme caution, wait until it is safe, and pass on the left side of the streetcar.”

What may happen to a car parked in a streetcar guide-way?

A fine and towing. A streetcar on rails cannot steer around a parked car, so one car on the guide-way stops the whole line. DC Driver Manual, p.69: “District law prohibits parking, stopping, or standing a vehicle on or within a streetcar guide-way or adjacent to a streetcar platform.”

When may you leave the right side of the road in the District?

To pass or to make a left turn. Traffic coming the other way expects the left side of your lane to be clear, and drifting there invites a head-on crash. DC Driver Manual, p.71: “You should keep to the right, except when your vehicle is about to overtake and pass another vehicle or cyclist, or to make a left turn.”

For at least how many feet must you signal continuously before turning in the District?

100 feet. Drivers and cyclists behind you need time to see the signal and slow down before you start the turn. DC Driver Manual, p.71: “You must use a turn signal, arm or hand signal, or both, continuously for at least 100 feet before turning.”

On which roads is it legal in the District to pass on either the left or the right?

One-way roads with room for two lines. On a one-way road with two lines of traffic there is no oncoming car, so a pass on either side does not cross into danger. DC Driver Manual, p.71: “However, in the District of Columbia, it is legal to pass on either the left or right on one-way roads, provided there is room for more than one line of traffic.”

On a two-lane highway, which marking on your side of the center means you must not pass?

A solid yellow line. Solid yellow on your side marks a stretch where the road ahead hides oncoming cars, so crossing it could put you face to face with one. DC Driver Manual, p.71: “Where the solid yellow line is on your side of the center of the roadway”

Before crossing the center line to pass on a two-lane highway, what must you be certain of?

There is time to pass and get back. A pass you cannot finish leaves you in the oncoming lane with a car closing on you head-on. DC Driver Manual, p.72: “Before you cross the center line, be certain there is time to pass and get back into the right lane before meeting a vehicle coming in the opposite direction and before a no-passing zone begins.”

What must you do when another vehicle is passing you?

Keep right and do not speed up. Speeding up while someone is beside you traps them in the oncoming lane with no gap to return to. DC Driver Manual, p.72: “If you are driving the vehicle being overtaken, give way to the right in favor of the overtaking vehicle.”

On a road with marked lanes, what must you not do?

Drive partly in two lanes at once. A car straddling two lanes blocks both and gives drivers on either side no clear space beside you. DC Driver Manual, p.72: “You must not drive partly in one lane and partly in another”

How should you position your vehicle for a right turn?

In the far-right lane, well ahead. Turning from a middle lane or into a far lane cuts across cars that are going straight. DC Driver Manual, p.73: “Get into the lane furthermost to the right, well ahead of the turn”

Into which lane should a left turn bring you?

The left lane going your way. Ending in the left lane keeps you clear of cars turning right from the other direction into the same street. DC Driver Manual, p.73: “Get into the left lane on your side of the highway well ahead of the turn”

In the District, when must your headlights be on during the day?

When your wipers are on. Rain makes your car hard to see as well as making the road hard to see, and headlights let others spot you. DC Driver Manual, p.73: “Always turn on headlights when the windshield wipers are on.”

When should you use low beams?

When closely following another vehicle. High beams bounce off fog straight back into your eyes and blind other drivers, so low beams let everyone see better. DC Driver Manual, p.73: “Use low beams when approaching or closely following other vehicles.”

Which driving habit saves fuel?

Anticipating stops to avoid hard braking. Flooring it and braking hard waste fuel, and the same smooth habits also keep you from rear-ending someone. DC Driver Manual, p.74: “Anticipate stops to minimize hard braking”

What must you do when you park your vehicle on a street?

Stop the engine and set the brake. A car left running or out of gear can roll into traffic or be driven off by someone else. DC Driver Manual, p.75: “When parking your vehicle on a street, you must stop the engine, lock the ignition, remove the key and set the parking brake.”

When parallel parking, within how many inches of the curb must your vehicle be?

12 inches. A car parked far from the curb sticks into the travel lane where passing cars and cyclists can hit it. DC Driver Manual, p.75: “When parallel parking on a two-way street, make sure the space is large enough for your vehicle and you must park parallel to and within 12 inches of the curb.”

What is double parking?

Stopping beside a car already at the curb. A double-parked car forces drivers and cyclists to swerve into the next lane without warning. DC Driver Manual, p.76: “Double parking a vehicle is prohibited because it blocks traffic and causes crashes.”

Which way should you turn your front wheels when parking downhill next to a curb?

Toward the curb. If the brake fails, the front tire rolls into the curb and stops the car instead of letting it run into traffic. DC Driver Manual, p.76: “Toward the curb when parking downhill”

When may you park on the traveled part of a highway?

When the vehicle is disabled. Cars at highway speed expect the lane ahead to be moving, and a parked car in it is a sudden wall. DC Driver Manual, p.76: “You must never park on the paved or traveled part of any highway unless your vehicle is disabled and cannot be moved.”

At a yield sign, when should you come to a full stop?

When traffic blocks the road ahead. Rolling into a yield when the road is busy pushes you into someone who has the right to be there. DC Driver Manual, p.77: “Where there is a yield sign and vehicles or pedestrians keep you from using the roadway beyond the sign, you should come to a full stop and proceed when the way is clear”

Where are you forbidden to stop your vehicle?

Within an intersection. A car stopped on a crosswalk or sidewalk forces people walking into traffic, and one in an intersection blocks every direction. DC Driver Manual, p.77: “Except when necessary to avoid a conflict with other traffic, or in compliance with the direction of a police officer or official traffic control device, do not stop a vehicle:”

Within how many feet of a driveway or alley must you not park?

5 feet. A car parked tight to a driveway blocks people from getting out and hides them when they do. DC Driver Manual, p.78: “In front of or within 5 feet of a private driveway, public driveway or alley”

Where must you not stand or park your vehicle?

On a hill brow with no-passing lines. On a curve or hilltop the view is already short, and a parked car there is found too late to avoid. DC Driver Manual, p.78: “On a curve or the brow of a hill where solid lines indicating a no passing zone appears on the surface of the road”

Where should you start a turnabout in close quarters?

At the extreme right side of the road. Starting at the far right gives you the most room to swing across, so you finish the turn in fewer moves. DC Driver Manual, p.79: “Start from the extreme right side of the road.”

Which speed rules must you obey in the District?

Both the general rule and posted limits. A posted limit is set for good weather, so going that fast in rain or a crowd can still be too fast. DC Driver Manual, p.79: “District of Columbia traffic laws provide both a general speed restriction and specific speed limits.”

Unless posted otherwise, what is the speed limit on District city streets?

20 mph. City streets are full of people walking and biking, and a person hit at 20 mph is far more likely to live than one hit faster. DC Driver Manual, p.80: “District of Columbia city streets is 20 miles per hour”

What can happen if you exceed an advisory speed and then crash?

You may be ticketed for unsafe speed. The advisory speed marks a curve or ramp where going faster can throw you off the road, whatever the posted limit says. DC Driver Manual, p.80: “Although an advisory speed sign does not have the force of law, if you exceed it and have a crash, it may be concluded that you violated the general speed restriction and may be subject to a ticket.”

What is a safety zone on a roadway?

An area marked for pedestrians only. People wait in a safety zone believing cars will not come through it. DC Driver Manual, p.80: “Never drive through a safety zone, which is an area on a roadway marked by signs for pedestrians only.”

Why should you not coast in neutral?

You may not get back in gear in time. In neutral the engine is not connected to the wheels, so if you need to speed up to get out of trouble you cannot. DC Driver Manual, p.80: “Never drive with the gears in neutral or the clutch pedal depressed longer than is needed to shift gears.”

Whose directions must you follow at a school crossing?

The authorized crossing guard. A guard can see children or a crowd stepping off the curb that you cannot, and their signal overrides the light. DC Driver Manual, p.80: “You must follow the direction of any authorized crossing guard or traffic control officer.”

You may not make a U-turn on a curve or hill unless your vehicle can be seen from how many feet away?

500 feet. A car swinging across the road where others cannot see it in time is a broadside crash waiting to happen. DC Driver Manual, p.81: “You cannot make a U-turn on a curve or hill where the vehicle cannot be seen at least 500 feet away by the driver of another vehicle proceeding in either direction.”

While driving in the District, which of these may you not wear?

Earphones attached to a music player. Music in both ears drowns out sirens, horns and train bells you need to hear. DC Driver Manual, p.81: “A person may not wear earplugs, a headset, or earphones attached to a radio, tape player, CD player or other audio device while driving a motor vehicle.”

What is unlawful under District motor vehicle law?

Removing a catalytic converter. Safety and emission equipment is there to prevent crashes and dirty air, and taking it off puts others at risk. DC Driver Manual, p.81: “Remove or alter any safety device or equipment which has been placed upon any motor vehicle, trailer, semi-trailer, or pole trailer in compliance with any law, rule, regulation or requirement of the United States or of the District of Columbia”

Who must wear a seat belt in a passenger car in the District?

The driver and all passengers. In a crash an unbelted rider keeps moving at the car's speed and hits the dashboard, the windshield or the people in front. DC Driver Manual, p.82: “The District of Columbia law requires that the driver and all passengers wear seat belts in passenger cars, trucks, tractors, multi-purpose vehicles or passenger buses.”

Where should you adjust your head restraint?

Directly behind your head. When you are hit from behind your head snaps back, and a head rest set too low lets it swing past and strain your neck. DC Driver Manual, p.82: “Before starting to drive the vehicle, adjust the head rest on your seat to a position directly behind your head.”

In the District, children under what age must ride in a child safety seat in the back seat?

3 years. A small child's body is too small for an adult belt, and a fitted seat in the back holds them where a crash does least harm. DC Driver Manual, p.82: “In the District of Columbia, the operator of a motor vehicle may not transport any child less than 3 years of age unless the child is properly secured in a child safety seat in the back seat of the vehicle.”

Should you wear a seat belt in a car that has air bags?

Yes, air bags work best with belts. An air bag cushions you only from the front, and without a belt you can slide under it or be thrown sideways. DC Driver Manual, p.83: “They work best when drivers and passengers are properly secured by lap and shoulder belts and are sitting as far back as possible.”

What is a work zone?

Where road or utility work is happening. Knowing what a work zone is tells you when to expect workers, machines and narrowed lanes near the road. DC Driver Manual, p.83: “A work zone is an area along a highway where construction, maintenance, or utility work is occurring.”

What may a regulatory sign posted in a work area tell you?

The speed limit there is lower. Workers stand a few feet from moving traffic, so the lower limit gives you time to react to them. DC Driver Manual, p.86: “Speed limits may be reduced in work areas.”

Which devices are most commonly used to guide drivers safely through work areas?

Barricades, cones and drums. They mark a path around the digging and the crews, so following them keeps your car out of the hole. DC Driver Manual, p.86: “Barricades, cones and drums are the most commonly used devices to guide drivers safely through work areas.”

What are changeable message signs often used for in work zones?

Alerting drivers to special conditions. The message can change as the work changes, so it can tell you about a lane closure that was not there yesterday. DC Driver Manual, p.86: “These electronic signs, which can display a variety of messages pertaining to road conditions, traffic problems, emergency situations, special events, etc., are often used to alert motorists to special conditions within work zones.”

What does an arrow panel in a work area tell you?

Where to move into another lane. Moving over early, when the arrow first shows, saves you from a last-second swerve at the closed lane. DC Driver Manual, p.86: “Arrow panels are used both during the day and at night to give advance warning and directional information to tell drivers where it is necessary to move into another lane to the right or left.”

Who must obey traffic signals on a street or highway?

People walking, driving or biking. A signal works only if every person at the corner follows the same light, whether on foot, on a bike or in a car. DC Driver Manual, p.86: “Traffic signals apply to everyone who is walking, driving or riding a bicycle on a street or highway.”

On a traffic signal hung top to bottom, which light is usually at the top?

Red light. Knowing the order lets you read a signal when glare or a burned-out bulb makes the colors hard to tell apart. DC Driver Manual, p.87: “Traffic signals are usually red, yellow and green from top to bottom, or left to right.”

What must you do at an intersection where the traffic lights are not working?

Stop as you would for a stop sign. When the lights are dark, drivers on both roads may think they have the green, and a full stop is what keeps them from meeting in the middle. DC Driver Manual, p.87: “The law requires that if the traffic lights or controls are out of service or malfunctioning when you approach and intersection, you must come to a stop as you would for a stop sign.”

At a steady red signal with no stop line, where must you stop?

Before entering the crosswalk. Stopping short of the crosswalk leaves it clear for the people the red light is letting cross. DC Driver Manual, p.87: “If not, you must stop before entering the crosswalk and remain stopped as long as the signal is red.”

What does a steady yellow signal mean?

The light is changing from green to red. Yellow is the warning before red, and treating it as a dare is how drivers end up in the intersection on red. DC Driver Manual, p.87: “This means that the signal is changing from green to red.”

What should you check before you go on a steady green signal?

That other vehicles have cleared. A driver who ran the end of the yellow may still be crossing when your light turns green. DC Driver Manual, p.87: “Proceed with caution after you have checked first to see that other vehicles have cleared the intersection.”

You want to turn left and the left-turn arrow is a steady red. What should you do?

Stay stopped until the arrow changes. The red arrow holds turning cars while people cross or oncoming traffic moves through. DC Driver Manual, p.87: “Come to a complete stop before reaching the intersection, stop line or crosswalk for the direction indicated by the arrow.”

What must you do at a flashing red signal?

Stop fully, yield, then go when clear. A flashing red is often a quiet corner where drivers grow careless, and it asks the same full stop as a stop sign. DC Driver Manual, p.88: “You must come to a complete stop, yield to all other traffic and to pedestrians.”

What do flashing red lights and bells at a railroad crossing tell you?

A train is coming; stop and wait. A train cannot swerve or stop in time, so the lights are your only chance to stay out of its way. DC Driver Manual, p.88: “Flashing red signals, which may be accompanied by bells, warn you that a train is coming.”

How should you approach a railroad crossing that has no lights or gates?

Slow down, look and listen for a train. Nothing at that crossing will warn you, so your own eyes and ears are the only alarm there is. DC Driver Manual, p.88: “When approaching a railroad crossing that does NOT have any warning system (such as flashing lights or gates), it’s important to slow down, look and listen for any sign of an oncoming train and then stop before the tracks if there is one coming.”

What does an X with the letters RR painted on the road warn you of?

Railroad tracks just ahead. The marking comes before the crossing so you start looking for a train while you still have room to stop. DC Driver Manual, p.88: “Markings on the road, consisting of a white “X” and the letters “RR”, alert you that you are about to cross railroad tracks and need to watch for trains, which can’t stop quickly.”

What does a flashing yellow signal tell you to do?

Slow down and go with caution. Cross traffic or people walking may appear, and slowing gives you the room to stop for them. DC Driver Manual, p.88: “You must slow down and proceed with caution.”

What are lane use signals over a road used for?

Reversing lane direction by the hour. A lane that carries you into town in the morning may carry traffic toward you in the evening. DC Driver Manual, p.88: “The signals are used to control traffic flow by reversing lanes direction during different hours of the day.”

What does red on a road sign tell you?

Stop, yield, do not enter or wrong way. Red is kept for the signs that tell you to stop or not go on, so you react to it before you read it. DC Driver Manual, p.90: “Stop, yield, do not enter, or wrong way”

Why is it worth knowing what each sign shape means?

In fog you may see only the shape. When fog washes out the words and color, the outline is what is left to tell you what the sign says. DC Driver Manual, p.92: “In poor visibility conditions, such as heavy fog, you may be able to make out only the shape of a sign.”

At this sign there is no stop line and no crosswalk. Where must you stop?

Before the posted sign. Stopping in the right place keeps your car out of the crosswalk and gives you a clear look at cross traffic. DC Driver Manual, p.95: “When you come to a stop sign, you must make a complete stop at the stop line.”

What do overhead lane use signs at an intersection show?

Which turns are made from which lanes. Reading the sign over your lane before the corner keeps you from being stuck in a lane that must turn. DC Driver Manual, p.96: “These signs are used where turning movements are required or where unconventional turning movements are permitted from specific lanes at an intersection.”

What does this sign warn you of?

A sharp turn to the right ahead. A sharp turn needs much more slowing than a curve, so you brake before it, not in it. DC Driver Manual, p.97: “There is a sharp turn to the right in the road ahead.”

What should you do when you see this sign?

Slow down and get ready to stop ahead. The stop sign may be hidden by a hill or a bend, and this warning keeps you from finding it too late. DC Driver Manual, p.98: “Slow down and be ready to stop at the stop sign ahead.”

What does a 4-WAY plate under a stop sign tell you?

Traffic from every direction must stop. Knowing every driver must stop tells you nobody has a free pass through the intersection, you included. DC Driver Manual, p.99: “This sign means there are four STOP signs at the intersection.”

What should you do when you see a sign warning of a yield sign ahead?

Slow and get set to stop or fit in. Arriving at a yield at full speed leaves you a choice between cutting someone off and braking hard. DC Driver Manual, p.99: “Slow down and be prepared to stop at the yield sign or adjust your speed to the flow of the traffic.”

What should you do when a sign warns of a winding road ahead?

Adjust your speed for the curves. One curve after another gives you no straight stretch to recover if you enter the first one too fast. DC Driver Manual, p.100: “The road ahead is winding with a series of curve or turns. Adjust your speed.”

A sign warns that a side road enters from the right. What should you do?

Adjust speed to watch for cars there. A car can pull out of a side road into your lane with little warning, and a lower speed gives you time. DC Driver Manual, p.100: “A side road enters the highway from the right. Adjust your speed so you can see any vehicles entering or exiting from the side road.”

Where is this sign placed, and what does it point to?

On the left, at the start of a no-passing zone. It is placed where you look to pass, so you see it before you pull out into a lane you cannot finish in. DC Driver Manual, p.101: “The pennant is located on the left side of a roadway and points to beginning of a no-passing zone.”

What does an exit advisory speed sign show?

The top safe speed for the ramp. Ramps often curve tighter than the highway, and taking one at highway speed can push you off the edge. DC Driver Manual, p.101: “The maximum safe speed for an entrance or exit.”

What does this sign warn you of?

Traffic merging from the right. Cars joining from the right need room, and seeing them coming lets you adjust before you are side by side. DC Driver Manual, p.102: “Merging traffic from the right is just ahead.”

At an intersection merge, where two lanes become one, who is responsible for merging safely?

Drivers in both lanes. Neither lane has the right to the space, so both drivers have to watch and adjust or they meet in the middle. DC Driver Manual, p.102: “Two lanes of traffic moving in the same direction are about to become one. Drivers in both lanes are responsible for merging safely.”

What should you do when you see this sign?

Check your brakes for the grade. Going down a steep hill makes the car pick up speed, and you need to know your brakes will hold before you start. DC Driver Manual, p.105: “A steep grade is ahead. Check your brakes.”

What does a CAUTION DRIVE SLOWLY sign warn you about?

Animals, joggers, cyclists and walkers. People and animals near the edge of the road can step out, and driving slowly gives you time to stop. DC Driver Manual, p.106: “This Caution sign warns of Animals, Joggers, Bicyclists and Pedestrians that may be near the roadway.”

Besides turning, when else are turn signals required?

When changing lanes or overtaking. The driver beside or behind you cannot read your mind, and a signal tells them you are about to move into their path. DC Driver Manual, p.107: “Turn signals are required when changing lanes or overtaking a vehicle.”

A slow-moving vehicle sign is shown by vehicles that travel at what speed or less?

25 mph. You can close on a slow vehicle much faster than you expect, and the sign tells you it is barely moving. DC Driver Manual, p.107: “Vehicles traveling at 25 MPH or less, such as farm equipment, horse-drawn vehicles or highway work vehicles, must display these signs when using a public highway.”

What does this sign mean?

You may not turn right here. A right turn here may cross a busy crosswalk or a lane you cannot see, which is why it is banned. DC Driver Manual, p.108: “Right turns are illegal. Do not make a right turn when you see this sign.”

What does an interstate route marker look like?

A red and blue shield. Knowing the interstate shield lets you follow a highway number without mistaking it for a smaller road. DC Driver Manual, p.109: “The interstate system has route markers in the shape of a shield.”

What does it mean if you see red reflectors on the pavement facing you?

You are going the wrong way. If you see red reflectors facing you, you are driving against traffic and need to get out at once. DC Driver Manual, p.111: “Red reflectors on the pavement show areas not to be entered or used.”

What does a broken yellow center line mean?

Passing is allowed both ways when clear. A broken line means drivers on both sides may use the other lane to pass, so you check for them too. DC Driver Manual, p.111: “Broken yellow center lines mean that passing on the left is allowed in either direction when the way ahead is clear.”

What do broken white lines mean?

Same-direction lanes; change with care. A broken white line lets you move over, but the lane beside you is full of cars going your way at speed. DC Driver Manual, p.112: “Broken white lines separate lanes of traffic going in the same direction. You may change lanes with caution.”

Your lane has a curved arrow and the word ONLY. What must you do?

Turn the way the arrow points. Drivers behind and beside you expect the whole lane to turn, so going straight from it cuts across them. DC Driver Manual, p.113: “If you are in a lane marked with a curved arrow or a curved arrow and the word ONLY, you must turn in the direction of the arrow.”

What does a line of triangles painted across the road show?

Where to yield or stop if needed. The triangles show exactly where to wait so you do not roll into traffic already circling. DC Driver Manual, p.114: “Yield line is a line of triangles extending across the roadway that may be used with a yield sign to show the point at which you must yield or stop, if necessary.”

On a three-lane road, the center lane has a broken yellow line on both sides. What is it for?

Passing, for traffic either way. Both directions can use that lane to pass, so you check for an oncoming driver doing the same. DC Driver Manual, p.114: “If the center lane is marked by a single broken yellow line on both sides, drivers traveling in either direction may use the center lane for passing.”

What does a bicycle symbol with a double chevron arrow above it, painted in a travel lane, tell drivers?

Expect bicyclists riding in this lane. In a lane too narrow to share, a cyclist may ride in the middle of it, and the marking tells you that is expected. DC Driver Manual, p.115: “Sharrows clarify where bicyclists are encouraged to ride in the lane and remind drivers to expect bicyclists on the road.”

When may a driver drive in a bicycle lane?

When needed to turn left or right. The bike lane is the cyclist's space, and a car using it as a passing lane runs them down from behind. DC Driver Manual, p.115: “Drivers should not drive in the bicycle lane except when necessary to turn left or right.”

What marking in the center of a highway lane shows it is an HOV lane?

A diamond shape. Spotting the diamond tells you the lane has rules about riders before you pull into it. DC Driver Manual, p.115: “High Occupancy Vehicles (HOV) lanes are marked on highways by a diamond shape in the center of the lane.”

Where these come from

Every rule here is checked against DC Driver Manual, published by the District of Columbia Department of Motor Vehicles, and against the state code itself. Last checked 2026-10-05.
