Louisiana Permit Practice Test — Written Test, 40 Questions

Free 10-question Louisiana permit practice test, then full 40-question tests like the real exam (32 to pass), each question cited to the Class D & E Driver's Guide.

The exam

The Louisiana Department of Public Safety knowledge test is 40 questions, and 32 correct is a pass. Everything on it comes out of Class D & E Driver's Guide. Officially it is the knowledge test; most people call it the written test, or the permit test.

Louisiana does not state the score that passes its knowledge test directly: 32 of 40 follows from what it does state (the Louisiana Office of Motor Vehicles' Permits page, expresslane.la.gov: “also pass a 40 question test with a minimum score of 80%.” The 32 is 80% of it, the rate the Driver's Guide also states on printed p.8).

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 Louisiana 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 Class D & E Driver's Guide or Louisiana’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 Louisiana test

Who must hold a Louisiana driver's license to drive on public roads?

Any Louisiana resident who drives on them. Living here and driving here go together: the state needs to know every resident behind the wheel has proven they can drive. Class D & E Driver's Guide, p.1: “You must have a Louisiana driver’s license if you are a resident of Louisiana and want to drive a motor vehicle on public streets and highways.”

Which license class covers an ordinary car that weighs under 10,001 pounds?

Class E. Most family cars, vans and pickups weigh far less than 10,001 pounds. That is why Class E is the license most new drivers get. Class D & E Driver's Guide, p.2: “CLASS “E” - Permits the operation of any single motor vehicle under 10,001 pounds, recreational vehicles and certain farm use vehicles not defined as commercial vehicle.”

What is the minimum age for a Louisiana Class D license?

17 years old. Class D lets you drive heavier work trucks. The state wants a bit more age and road time before you take one on. Class D & E Driver's Guide, p.4: “Class D - Minimum seventeen (17) years of age.”

Whose signature is needed on a license for an applicant who is 17 or younger?

The custodial parent or legal guardian. A parent who signs agrees to the teen driving and takes part in the choice. The state will not license a minor without that say-so. Class D & E Driver's Guide, p.3: “The signature of the custodial parent or legal guardian is required for the issuance of any license (including first time applications, duplicates and changing restrictions).”

What are the three stages of Louisiana's graduated licensing program?

Learner's permit, intermediate, then full license. New drivers crash the most. Moving up in steps lets them gain skill in safer settings before they drive with no limits. Class D & E Driver's Guide, p.6: “under a Graduated Licensing Program which has three stages of licensure:”

What is the minimum age for a Louisiana learner's permit?

15 years old. At 15 a teen can start learning with a grown-up beside them. This gives a full year of practice before driving alone. Class D & E Driver's Guide, p.7: “1. Must be a minimum of fifteen (15) years of age.”

What test must you pass to move up to an intermediate license?

The road skills driving test. Before a teen drives alone, an examiner has to see them handle real traffic safely, not just answer questions. Class D & E Driver's Guide, p.7: “3. Must pass the road skills driving test with at least 80% accuracy.”

Which applicant may get a full license without going through stages 1 and 2?

One who is 17 or older at first application. Older first-time drivers skip the teen steps because the extra crash risk is mostly in younger, newer drivers. Class D & E Driver's Guide, p.7: “2. Must be at least seventeen (17) years of age prior to application for first license.”

What kind of insurance must cover any vehicle used on Louisiana highways?

Liability insurance. If you hurt someone or wreck their car, liability insurance pays them. Without it, the victim may be left with the bills. Class D & E Driver's Guide, p.7: “Any vehicle used upon the highways of Louisiana must be insured by liability insurance or other allowable substitute.”

When does the OMV screen your vision?

When you apply for or renew a license. Eyesight can change over the years. Checking at each new license and renewal catches problems before they cause a crash. Class D & E Driver's Guide, p.8: “Your eyes will be screened when you apply for or renew your driver’s license or learner’s permit.”

What must your vehicle have for an OMV road skills test?

A valid inspection sticker. The examiner rides in your car. A car that is not safe or legal could hurt you both before the test even starts. Class D & E Driver's Guide, p.9: “The vehicle must be in safe driving condition, pass a safety inspection, and have a valid inspection sticker, current license plate and registration document.”

How long after your nearest birthday does a Louisiana license expire?

6 years. Renewing on a set schedule lets the state recheck your eyes and keep your record and photo current. Class D & E Driver's Guide, p.10: “Your driver’s license will expire six years from your nearest birthday.”

What can happen if you drive in violation of a restriction on your license?

Your driving privileges may be suspended. A restriction, like needing glasses, is there because you are not safe without it. Ignoring it puts others at risk. Class D & E Driver's Guide, p.11: “A violation of a restriction is a violation of the law and may result in the suspension of your driving privileges.”

You are in a crash where someone is hurt. What can cost you your license?

Leaving without stopping to help. A hurt person may need help in the first minutes. A driver who flees can leave them to die. Class D & E Driver's Guide, p.12: “Failure to stop and render assistance at a collision in which you were involved that results in the injury or death of a person.”

What can happen if you give false facts on a license application?

You can lose your privilege to drive. The state decides who may drive based on what you tell it. A lie on the form can put an unsafe driver on the road. Class D & E Driver's Guide, p.12: “Making a false statement or concealing a material fact on an application for a driver’s license.”

Which of these is an example of simple littering?

Trash flying out of a pickup bed. You can break the litter law without meaning to. Trash that blows out of your truck bed still counts. Class D & E Driver's Guide, p.13: “Simple littering is unintentional littering, such as trash flying out the back of a pickup truck.”

What fine can a first offense of simple littering bring?

$150. A real fine, even for the first time, reminds drivers that a tossed cup costs the state money to pick up. Class D & E Driver's Guide, p.14: “penalties for simple littering range from a first offense of a $150 fine or eight hours of community service to a $900 fine or 20 hours of community service for a second offense.”

What are the three main parts of the Highway Transportation System?

People, vehicles and roads. Every crash involves at least one of these. Knowing all three helps you think about what can go wrong. Class D & E Driver's Guide, p.17: “The Highway Transportation System consists of three major components:”

Which way does an even-numbered interstate highway run?

East and west. Knowing the number pattern helps you tell which way an interstate goes without a map. Class D & E Driver's Guide, p.20: “EVEN numbered highways go East and West.”

How much rain can make your tires lose traction?

Even a light drizzle. A light rain mixes with oil on the road and makes it slick. Many drivers do not slow down for it. Class D & E Driver's Guide, p.20: “Rain, even a drizzle, can cause a vehicle’s tires to lose traction.”

Who else, besides signs and signals, gives traffic directions you must obey?

Police, highway workers and crossing guards. A crossing guard can see the children you cannot. If drivers ignored the guard, kids would be hit. Class D & E Driver's Guide, p.22: “Traffic control also can be provided by law enforcement, highway personnel or school crossing guards.”

Which signs use the eight-sided shape?

Stop signs only. No other sign shares this shape, so you know to stop even if snow covers the word. Class D & E Driver's Guide, p.23: “The octagon shape sign is used exclusively for stop signs.”

What does the color red mean on a traffic sign?

Stop or do not. Red is saved for the signs that can stop a crash, like the one that keeps you off a ramp the wrong way. Class D & E Driver's Guide, p.24: “Means “Stop” or “Do Not” anytime you see this color”

What does this sign mean?

A cross road is ahead. Cars may come from the left or the right at the next crossing, so be ready to slow down. Class D & E Driver's Guide, p.25: “Cross Road Ahead”

Where must you stop at this sign?

Behind the stop line or crosswalk. Stopping behind the line keeps your car out of the crosswalk and out of the way of cross traffic. Class D & E Driver's Guide, p.27: “You must stop behind the stop line or crosswalk, if one is present.”

A school zone speed limit sign says WHEN FLASHING. When must you obey it?

Only while the lights flash. The lights flash when children are coming or going, which is when a slow car matters most. Class D & E Driver's Guide, p.27: “The speed limit is required only when flashing; otherwise obey the roadways speed limit.”

What do lane use control signs tell you?

Where you can go or turn from a lane. If you are in a lane that must turn, these signs tell you before you reach the corner. Class D & E Driver's Guide, p.27: “These black and white signs tell you where you can go, where you can turn and often use an arrow symbol.”

What does a PASS WITH CARE sign tell you?

The no passing zone has ended. The road ahead is now open enough to see, but you still must check that the other lane is clear. Class D & E Driver's Guide, p.28: “Pass with Care – This sign tells you that you are at the end of a no passing zone.”

What does this kind of sign help you find?

Services such as hospitals. On a long trip you may need help fast, like a hospital, and these signs point the way. Class D & E Driver's Guide, p.30: “They show the location of various services such as rest areas, gas stations, hotels or hospitals.”

What is the main job of guide signs?

To direct you to places and roads. Guide signs do not give orders. They help you find your way so you are not lost or turning late. Class D & E Driver's Guide, p.29: “They give information on intersecting roads, help direct you to cities and towns, and show points of interest along the highway.”

What do incident signs warn you about?

Unplanned closures or detours. A crash or a spill can close a road with no notice, and these signs give you time to react. Class D & E Driver's Guide, p.30: “Incident Signs - These signs are temporary and let you know when you should be prepared to stop or when roadways are closed or detoured due to a road user incident, natural disaster, hazardous material spill, or other unplanned incident.”

Near orange work zone signs, what may you need to do?

Slow down, stop or change lanes. Road crews work a few feet from moving cars, so you must be ready to change what you are doing. Class D & E Driver's Guide, p.31: “You may need to slow down, stop, or change lanes.”

The stripes on a barricade slope downward to the left. Which way should you go?

Bear to the left. The stripes point you the safe way around the work, like an arrow made of paint. Class D & E Driver's Guide, p.32: “Stripes sloping downward to the left mean the driver should bear to the left.”

On a vertical traffic light, which light is on top?

Red light. If glare hides the colors, the position of the lit lamp still tells you what it means. Class D & E Driver's Guide, p.33: “Traffic lights are usually at intersections and are red, yellow and green from top to bottom, when on the same signal.”

You are stopped and your light turns green. What must you do before going?

Let crossing traffic clear first. A car running the late red may still be crossing, and pulling out at once puts you in its path. Class D & E Driver's Guide, p.33: “If you are stopped at the intersection and the light turns green, you must allow crossing traffic to clear the intersection before you go ahead.”

What does a flashing yellow light mean?

Slow down and go with caution. The light is not stopping anyone, so other cars may come in from the side at any time. Class D & E Driver's Guide, p.33: “Flashing YELLOW Traffic Light – This warning means slow down, look for any traffic entering the intersection and proceed with caution.”

What does a green arrow mean?

Turn that way if it is clear. The arrow gives you the turn, but a walker or a late car may still be in the way. Class D & E Driver's Guide, p.33: “GREEN Arrow – This means you can turn in the direction of the arrow, if the intersection is clear of other roadway users.”

What do yellow center lines separate?

Traffic going opposite directions. If you are left of a yellow line, you are in the lane where cars come at you. Class D & E Driver's Guide, p.34: “Yellow center lines are used to separate traffic in opposite directions.”

What do white lane lines separate?

Lanes going the same way. A white line tells you the car in the next lane is going your way, not coming at you. Class D & E Driver's Guide, p.35: “White lines separate lanes of traffic moving in the same direction.”

You see red raised reflectors in the road ahead of you. What do they tell you?

You are going the wrong way. If you see red reflectors facing you, you are headed into oncoming traffic and must get out safely. Class D & E Driver's Guide, p.35: “Red Raised Pavement Marking or reflectors indicate going against the direction of travel.”

You are in a turn-only lane but want to go straight. What should you do?

Make the turn and go around the block. A sudden lane change or stop surprises the drivers around you, and that is how crashes start. Class D & E Driver's Guide, p.37: “You must go ahead and make the turn.”

Why are roundabouts used?

They cut congestion and conflicts. Cars in a circle all go one way at low speed, so the worst side and head-on crashes go away. Class D & E Driver's Guide, p.37: “Roundabouts reduce traffic congestion and conflicts that are often the cause of crashes at traditional intersections.”

Under Louisiana's safety belt law, who in a car must be buckled up?

All passengers in the front and back seats. A rider in the back seat is hurt just as badly as one in front when nobody is buckled. Class D & E Driver's Guide, p.39: “Louisiana has a mandatory safety belt use law which requires all passengers in both the front and back seats in cars, vans and pickup trucks to be properly buckled.”

Where should the lap part of your safety belt fit?

Snugly across your hips. Your hip bones are strong and can take more of the force of a crash than your belly can. Class D & E Driver's Guide, p.39: “Your safety belt should fit snugly across your hips.”

What is one reason the manual gives for wearing a safety belt?

It keeps you inside the car. People thrown out of a car in a crash hit the road, a tree or another car, and most do not live. Class D & E Driver's Guide, p.39: “Buckling up helps keep you secure and inside your vehicle.”

What does Louisiana's Child Passenger Restraint law require?

Children ride in a restraint fit for age or size. A seat made for a much bigger or smaller child will not hold a child well in a crash. Class D & E Driver's Guide, p.40: “requires that all children must be properly restrained and secured in an age- or size-appropriate passenger restraint system which meets the applicable federal motor vehicle safety standards in effect.”

What does the manual say about holding a child on your lap while riding?

Never; you cannot hold them in a crash. In a crash a small child suddenly weighs far more than you can hold, and they fly out of your arms. Class D & E Driver's Guide, p.41: “NEVER HOLD A CHILD ON YOUR LAP OR BUCKLE YOURSELF AND A CHILD INTO A SINGLE SAFETY BELT.”

In what kind of crash does a front air bag inflate?

A head-on or nearly head-on crash. Air bags are built for front crashes, when your body is thrown toward the wheel and dash. Class D & E Driver's Guide, p.41: “An airbag is a flexible membrane that inflates rapidly with air or another gas during a head on or nearly head on collision.”

About how fast does an air bag come out when it deploys?

150 to 200 mph. That speed is why hands, arms and faces too close to the wheel can be badly hurt. Class D & E Driver's Guide, p.41: “The reason is that the air bag, when it deploys, comes out at speeds of 150 to 200 miles per hour.”

How far from a steering wheel with an air bag should you sit, at least?

10 inches. The bag needs room to fill up before it reaches you. Too close, and it hits you while still bursting out. Class D & E Driver's Guide, p.41: “Sit at least 10 inches away from the steering wheel equipped with an air bag - otherwise the bag can explode into you, causing serious harm.”

What do headrests protect you from?

Whiplash. When you are hit from behind, your head snaps back. A headrest set at the right height stops it. Class D & E Driver's Guide, p.42: “Headrests protect vehicle occupants from whiplash.”

What does Electronic Stability Control do?

Steps in to head off a loss of control. When a car is about to slide out of control, this system steps in to help keep it headed where you are steering. Class D & E Driver's Guide, p.43: “Electronic Stability Control, which intervenes to avert an impending loss of control”

When should you fix a defect that may affect how safely your car runs?

As soon as possible. A small problem like a bad brake light or worn tire can cause a crash if you wait to fix it. Class D & E Driver's Guide, p.44: “Any defect which may affect the safe operation of the vehicle should be corrected as soon as possible.”

What should you always do with your vehicle before you drive it?

A pre-trip inspection. A quick walk around and look over can find a flat tire or a leak before it causes trouble on the road. Class D & E Driver's Guide, p.44: “You should always conduct a “pre-trip” inspection of your vehicle before driving.”

How often does the manual suggest checking your license plate for readability?

Every month. Police and other drivers must be able to read your plate, even at night in their headlights. Class D & E Driver's Guide, p.44: “Check condition of license plate for readability and reflective properties, and damage or scratches, which would affect the appearance of the plate.”

What should you do before you get into your vehicle?

Walk around it and look for objects. A toy, a pet or a small child can be hidden right behind or under a car where you cannot see from the seat. Class D & E Driver's Guide, p.45: “Look in the front, under and behind, scanning for any objects in your travel path.”

Which gear should the car be in before you start the engine?

Park or neutral. If the car is in gear when it starts, it can jump forward or back into something. Class D & E Driver's Guide, p.45: “Make sure your car is in park or neutral gear.”

How should your headrest be positioned?

So it fully supports your head. A headrest set too low lets your head snap back over it if you are hit from behind. Class D & E Driver's Guide, p.46: “The headrest should be positioned so that it will fully support your head when you lean back.”

Which part of your foot should press the gas pedal?

The ball of your foot and toes. Using the front of your foot gives you fine control, so the car speeds up smoothly instead of lurching. Class D & E Driver's Guide, p.46: “Use the ball of your foot and toes, not the whole foot when accelerating.”

What are the three basic skills of driving the manual names?

Physical, social and mental. Handling the car is only part of it. You also have to deal well with other drivers and think ahead. Class D & E Driver's Guide, p.46: “There are three basic skills of the driving task.”

Which habit does the manual say helps your fuel economy?

Avoiding excessive idling. An idling car burns gas while going nowhere, and every hard start wastes even more. Class D & E Driver's Guide, p.47: “Avoid excessive idling”

Where is the correct tire pressure for your car usually found?

On a sticker by the driver's door. Each car has its own right pressure, so look it up for your car instead of guessing. Class D & E Driver's Guide, p.48: “The correct tire pressure for your vehicle is usually found on a sticker located on the driver side door jam.”

What happens when a car oversteers?

The rear tires lose grip first. When the back end slides out, the car turns more than you meant and feels like it is trying to spin. Class D & E Driver's Guide, p.48: “It is a phenomenon whereby the rear tires lose its traction before the front wheel during cornering.”

When should you use hand-to-hand, or push/pull, steering?

For normal driving above 10-15 mph. Pushing and pulling the wheel keeps your hands from crossing at normal speeds, so turns stay smooth. Class D & E Driver's Guide, p.49: “Use hand-to-hand steering, commonly called push/pull steering, when turning the wheel during normal driving activity going forward above 10-15 mph.”

What is the apex of a corner?

The furthest point inside the turn. Knowing the parts of a turn helps you plan when to slow down, when to steer and when to speed up again. Class D & E Driver's Guide, p.50: “The apex is the point where the car reaches the furthest point on the inside of the turn.”

What should you do when a light mist begins to fall?

Slow down and leave more space ahead. Even a little water mixes with oil on the road and makes it slick, so you need more room to stop. Class D & E Driver's Guide, p.51: “Slow down on slick roads, and increase your following distance even when mist begins to fall.”

What does the manual say about leaving a pet or child in a parked car in summer?

Do not leave them waiting in a car. A closed car gets very hot in the summer sun, and a child or pet left inside cannot get out. Class D & E Driver's Guide, p.51: “Do not leave pets or children waiting in a car.”

Why should you watch for patches of wet leaves in the fall?

They can be slippery. A patch of wet leaves can be as slick as ice and make your tires slide when you brake or turn. Class D & E Driver's Guide, p.52: “Once leaves become wet, they can present slippery and dangerous driving conditions.”

On a slick winter road, what should you do if your wheels start to lock up?

Ease off the brake. Locked wheels slide and cannot steer. Letting up on the brake lets them roll and grip again. Class D & E Driver's Guide, p.52: “Stop gently to avoid skidding.”

Before you start the engine, what should you make sure of?

Every passenger, including pets, is secured. In a crash, a loose child or dog is thrown around the car and can hurt everyone inside. Class D & E Driver's Guide, p.54: “Don’t start the engine without securing each passenger in the car, including children and pets.”

In the SIPDE method of defensive driving, what does the S stand for?

Sweep, Search, and Scan. Eyes that stay fixed on one spot miss the danger coming from the side or behind. Class D & E Driver's Guide, p.55: “S -Sweep, Search, and Scan (keep your eyes moving at all times to effectively see imminent danger)”

Which habit does the manual tie to the defensive-driving trait of anticipation?

Keeping a safe following distance. If you follow too close, you have no spare seconds to stop when the car ahead brakes hard. Class D & E Driver's Guide, p.55: “Defensive drivers maintain a safe following distance.”

You are very angry after an argument and need to go somewhere. What does the manual advise?

Let someone else do the driving. Strong feelings make you act on impulse and take risks you would not take when calm. Class D & E Driver's Guide, p.56: “If you are worried, nervous, angry, frustrated or depressed, let someone else drive.”

On a long drive, how often does the manual say a driver should rest?

Every 2 hours. Your focus fades over time behind the wheel, and a short stop brings it back before you drift. Class D & E Driver's Guide, p.56: “A driver should rest every two hours and not drive longer than six or eight hours a day.”

What is "highway hypnosis"?

Dulled senses and eyes fixed on the road. On a long, flat road your mind can switch off while your eyes stay open, so you miss what is around you. Class D & E Driver's Guide, p.56: “That is, your senses become dulled, your eyes become fixed on the road and you are not alert to traffic situations around you.”

When sharing the driving on a trip, how often should you switch drivers?

Every 2 hours. Sleepiness creeps up before you feel it, so trading off on a schedule keeps a fresh driver at the wheel. Class D & E Driver's Guide, p.57: “Switch drivers every two hours, even if you don’t feel tired.”

Which of these is a warning sign of drowsy driving?

Being unable to recall the last few miles. If you cannot remember the last few miles, your brain was already partly asleep at the wheel. Class D & E Driver's Guide, p.57: “Inability to recall the last few miles traveled”

What can an over-the-counter cold or allergy medicine do to your driving?

It can make you drowsy. A pill you can buy off the shelf can still make you as sleepy as a drink. Class D & E Driver's Guide, p.58: “Over-the-counter drugs taken for headaches, colds, hay fever or other allergies or those to calm nerves can make you drowsy and affect your driving.”

Which of these is an example of aggressive driving?

Following the car ahead too closely. Each of these acts on its own puts others at risk, and together they make a driver a danger to everyone nearby. Class D & E Driver's Guide, p.59: “Aggressive driving is a traffic offense or combination of offenses such as following too closely, speeding, unsafe lane changes, failure to signal intent to change lanes and other forms of negligent or inconsiderate driving.”

An aggressive driver is yelling at you from the next lane. What should you do?

Avoid eye contact and give them room. Staring at an angry driver can feel like a dare and make things worse. Class D & E Driver's Guide, p.59: “Avoid eye contact and steer clear, giving drivers plenty of room.”

How does the manual classify road rage?

A criminal offense. Road rage is not just rude driving: it is a crime that can put you in jail or in the hospital. Class D & E Driver's Guide, p.60: “Road rage is a criminal offense.”

How far ahead should you look while driving?

20 to 30 seconds. Seeing trouble early lets you slow down smoothly instead of slamming the brakes at the last second. Class D & E Driver's Guide, p.61: “Looking 20 to 30 seconds ahead will allow time to prepare for traffic conditions.”

At 60 mph on dry pavement, about how far can it take to react to a problem and stop?

359 feet. At highway speed your car covers more than a football field before it stops, so you must see danger very early. Class D & E Driver's Guide, p.62: “At 60 mph, it can take about 4 to 5 seconds or 359 feet to react to a problem and bring the vehicle to a stop.”

You are stopped at an intersection. In what order should you look before you go?

Left, right, then left again. The first lane you cross carries traffic from the left, so you check that side twice. Class D & E Driver's Guide, p.62: “If stopped, look left, right and left again before entering the intersection.”

Before you turn right, which traffic must you check for?

Traffic from your left and oncoming left-turners. A right turn puts you into the lane of cars coming from the left, so that side must be clear. Class D & E Driver's Guide, p.63: “Before turning right, make sure that there is no traffic approaching from your left and no oncoming traffic turning left into your path.”

When should you check traffic to the rear more often?

When traffic is heavy. In heavy traffic, cars close in from behind fast, so you need to know who is back there. Class D & E Driver's Guide, p.63: “You need to check to the rear more often when traffic is heavy.”

How should you check your blind spot before changing lanes?

Look over your shoulder toward the lane. Mirrors leave gaps beside the car, and a quick look over your shoulder is the only way to see them. Class D & E Driver's Guide, p.63: “Check your “blind spots” by turning your head and looking over your shoulder in the direction you plan to move.”

How should you set your driver's side mirror?

Head on the window, barely seeing your car's side. Pointing the mirror out this far covers the space beside you that the inside mirror cannot show. Class D & E Driver's Guide, p.64: “Place your head against the driver’s side window and adjust the driver’s side mirror so you can barely see the driver’s side of your car.”

What is the average perception time for an alert driver?

About 3/4 to 1 second. Even before your foot moves, your car keeps going while your brain works out what it sees. Class D & E Driver's Guide, p.64: “The average perception time for an alert driver is ¾ second to 1 second.”

If you double your speed from 20 to 40 mph, how much longer is your braking distance?

4 times longer. Speed does not add up in a straight line: a little more speed means a much harder hit and a much longer stop. Class D & E Driver's Guide, p.65: “When you double your speed from 20 to 40 mph the impact is 4 times greater. The braking distance is also 4 times longer.”

What following distance does the manual's basic rule call for?

3 seconds. Most people judge distance poorly, but counting seconds works the same in town and on the highway. Class D & E Driver's Guide, p.65: “Since most people have trouble judging distances, the “3-second rule” makes it easier for you. You can use it at any speed.”

How many seconds of following distance should you keep on wet pavement?

4 seconds. Wet roads make tires slip, so you need more room to stop than on a dry day. Class D & E Driver's Guide, p.66: “Increase the following rule (above) to four (4) seconds during bad weather or when driving on wet pavement.”

You need to turn around on a busy street. What does the manual say is better?

Circle the entire city block. Going around the block keeps you moving with traffic instead of stopping across it. Class D & E Driver's Guide, p.66: “Try to avoid turning around on a busy street. It is better to circle an entire city block.”

When should you use a three-point turnabout?

When it is too narrow to U-turn or circle the block. It leaves you crossways in the road for the longest time, so save it for when nothing else works. Class D & E Driver's Guide, p.67: “This is the most difficult and dangerous way to perform a turnabout.”

When should you use your parking brake?

Every time you park. The part that holds a car in park can break, and the parking brake keeps the car from rolling away. Class D & E Driver's Guide, p.67: “Whether your car is a manual or automatic, the terrain is hilly or flat, you should use your parking brake every time you park.”

You park facing downhill next to a curb. Which way should you turn your front wheels?

Toward the curb. If the brakes slip, the front tire rolls into the curb and stops the car instead of rolling into traffic. Class D & E Driver's Guide, p.68: “Facing downhill, turn your wheels toward the curb and shift into reverse or park.”

When pulling into an angle parking space, what must you make sure of?

Your rear will clear any parked car. If you turn in too early, the back of your car swings into the car parked next to the space. Class D & E Driver's Guide, p.68: “Make sure the rear of your car will clear any parked car.”

When you begin to parallel park, about how far from the car in front of the space should you stop?

18 inches. Starting in the right spot lines your car up to slide into the space in one smooth move. Class D & E Driver's Guide, p.69: “Signal, stop parallel to the front car (about 18 inches from it), with rear bumpers even.”

You are driving past a row of parked cars. Which clue suggests one may pull out in front of you?

Smoke coming from its tail pipe. A parked car about to pull out often shows a clue first, and spotting it gives you time to slow down. Class D & E Driver's Guide, p.69: “When driving past parked cars, watch for cars turning out in front of you.”

When parallel parked, how close to the right-hand curb must your right wheels be?

Within 18 inches. A car parked too far from the curb sticks into the lane, where passing cars can hit it. Class D & E Driver's Guide, p.70: “When parallel parked, the vehicle’s right wheels must be within 18 inches of the right-hand curb of the street.”

How close to a fire hydrant may you legally park?

No closer than 15 feet. Firefighters need to reach the hydrant fast, and a car in the way costs time in a fire. Class D & E Driver's Guide, p.70: “Within 15 feet of a fire hydrant or within 50 feet of a railroad crossing”

What does a white painted curb mean?

Only short stops are permitted. White curbs are for quick drop-offs and pickups, not for leaving your car. Class D & E Driver's Guide, p.70: “White - indicates that only short stops are permitted”

What is the striped access aisle next to an accessible parking space for?

Safe loading for people with disabilities. A person using a wheelchair or ramp needs that open space to get in and out of the car. Class D & E Driver's Guide, p.70: “The purpose the access aisle is to allow safe loading and unloading of equipment and to provide safe access for individuals with disabilities.”

You must finish passing before you come within how many feet of an oncoming vehicle?

100 feet. Cutting back in close to an oncoming car leaves no room if either driver makes a mistake. Class D & E Driver's Guide, p.71: “You must complete a passing maneuver before coming within 100 feet of any vehicle approaching from the opposite direction.”

When may you pass another vehicle on its right side?

When there are two or more lanes going your way. With two lanes going your way, there is a real lane to pass in. On a one-lane road there is no room on the right. Class D & E Driver's Guide, p.72: “You may pass to the right of another vehicle if there are two or more lanes of traffic moving in the same direction.”

On a road with several lanes each way, which lane is meant for passing slower vehicles?

The left-most lane. Keeping the left lane for passing lets faster cars get by without weaving around you on the right. Class D & E Driver's Guide, p.72: “On multi-lane roads, the left-most lane is intended to be used for passing slower vehicles.”

When are road surfaces most slippery?

Right after the rain starts to fall. The first rain lifts oil off the road and floats it on top, so the road can feel like ice. Class D & E Driver's Guide, p.74: “Road surfaces are most slippery immediately after the rain begins to fall.”

At about what speed does partial hydroplaning start?

35 mph. Above this speed the tires can't push water away fast enough, so they start to ride up on it. Class D & E Driver's Guide, p.74: “Partial hydroplaning starts at about 35 miles per hour,”

At night, how far ahead should you be able to stop?

Within the distance your headlights show. If you drive faster than your lights reach, something in the road shows up too late to stop for. Class D & E Driver's Guide, p.75: “When driving at night, you must be able to stop within the distance you can see ahead with your headlights.”

Louisiana law requires your headlights to be on between what times?

Sunset and sunrise. Parking lights are too dim for others to see you coming. Full headlights are what make you visible after dark. Class D & E Driver's Guide, p.75: “Louisiana law requires that your headlights (not just parking lights) be on between sunset and sunrise.”

What does a steady DON'T WALK signal mean?

Pedestrians must not enter the roadway. A steady DON'T WALK means traffic has the go. Stepping out puts a walker in front of moving cars. Class D & E Driver's Guide, p.76: “A steady signal means the pedestrians must not enter the roadway towards the signal.”

You are turning right on red and a pedestrian is crossing. Who has the right of way?

The pedestrian crossing in front of you. People on foot have no protection. Giving them the right of way where they are meant to cross keeps them from being hit. Class D & E Driver's Guide, p.76: “Pedestrians have the right of way when they are in a marked crosswalk, when crossing an intersection with a green traffic signal or walk signal, and over a vehicle making a right turn on red.”

To help a blind pedestrian, stop no more than how far from the crosswalk?

5 feet. A blind walker uses the sound of your engine to know where your car is. Stop close so they can hear you. Class D & E Driver's Guide, p.77: “Don't stop your car more than five feet from the crosswalk.”

You need to make a phone call while driving. What is the safe thing to do?

Pull off the road and stop first. Stopped on the side of the road, the call can't pull your eyes or mind away from traffic. Class D & E Driver's Guide, p.77: “If you must make a call, pull safely off the road and stop before making the call.”

Under Louisiana law, how may a driver use a wireless phone while driving?

Only hands free. Holding a phone ties up a hand you need for the wheel and pulls your eyes down. Class D & E Driver's Guide, p.78: “Anyone using any type of wireless communication device while operating a motor vehicle, unless they are hands free”

At an intersection, how should you treat a bicyclist?

Yield as you would to other vehicles. Bikes are small and easy to miss at a corner. Yielding to them as you would to a car keeps riders from being hit. Class D & E Driver's Guide, p.80: “You must yield to bicyclists in intersections as you would for pedestrians and other vehicles.”

You just passed a bicyclist and need to turn right. What should you do?

Slow down and stay behind the rider. Passing a bike and then turning right across it is a common way riders get hit. Class D & E Driver's Guide, p.80: “Do not swing in front of a bicyclist to make a right turn.”

What lights must a bicycle have when ridden at night?

A white front light and a red rear light or reflector. Without lights, a dark bike is close to invisible to a driver until it is too late. Class D & E Driver's Guide, p.81: “When riding at night, bicycles must have a white front light and a red rear light or reflector visible from the rear.”

What causes over two-thirds of car-motorcycle crashes?

A driver turning in front of the rider. Drivers often look right past a motorcycle when they turn. Look twice before turning across one. Class D & E Driver's Guide, p.81: “Research shows that over two-thirds of the car/motorcycle collisions are the results of the other driver turning in front of a motorcyclist.”

A loaded tractor trailer going 55 mph on a dry road needs at least how far to stop?

290 feet. A truck needs far more room to stop than a car. If you cut in close, it can't stop before it hits you. Class D & E Driver's Guide, p.83: “A tractor trailer loaded with freight, safe-rated tire, and properly adjusted brakes traveling at 55 miles per hour on a clear, dry roadway requires a minimum of 290 feet to come to a complete stop.”

In good weather, how much following distance should you leave behind a truck?

At least 4 to 5 seconds. Hanging back keeps road spray off your windshield and lets you see around the truck. Class D & E Driver's Guide, p.84: “In good road and weather conditions you should leave a gap of at least four to five (4-5) seconds between your vehicle and the truck in front of you, and an even longer gap when conditions are poor.”

Which papers should you be ready to show an officer at a traffic stop?

License, registration and proof of insurance. The officer needs to know who you are, that the car is registered and that it is insured. Having them ready keeps the stop short. Class D & E Driver's Guide, p.86: “Be prepared to produce your driver’s license, vehicle registration certificate, and current proof of insurance.”

The traffic light at an intersection is dark and not working. How must you treat it?

As an all-way stop sign. With the light dark, nobody knows whose turn it is. Making every driver stop keeps cars from crashing in the middle. Class D & E Driver's Guide, p.86: “When a traffic-control signal is not functioning at an intersection, the intersection shall revert to an all-way or four-way stop.”

How much more violent is a frontal crash at 35 mph than one at 30 mph?

About one-third more. Just 5 mph more makes a crash hit much harder. Small speed gains raise the harm fast. Class D & E Driver's Guide, p.86: “A frontal impact at 35 mph, for example, is one-third more violent than one at 30 mph.”

What is true of a posted minimum speed limit?

You must not drive slower than it. Very slow cars on a fast road make others brake hard or swerve, which leads to rear-end crashes. Class D & E Driver's Guide, p.87: “You must not drive slower than the posted minimum limit.”

How does Louisiana law define drag racing?

2 or more cars racing from side by side. Racers drive at top speed with their eyes on each other, not the road, and others get hurt. Class D & E Driver's Guide, p.87: “Drag racing is defined as the operation of two or more vehicles from a point side by side at accelerating speeds in a competitive attempt to outdo each other.”

When may you drive across the median of a divided highway?

Only at an approved cross-over. Cars cutting across a median pop up in front of fast traffic with no warning. Cross-overs are placed where you can be seen. Class D & E Driver's Guide, p.87: “When a highway is divided into two roadways by a median or barrier, you must not drive across the median or barrier except when an approved cross-over is provided.”

When changing lanes, which other drivers does the manual tell you to check for?

Drivers also moving into the same lane. Two cars can pick the same open gap at once, one from each side, and meet in the middle. Class D & E Driver's Guide, p.87: “Check for other drivers who may also be moving into the same lane.”

How far from a stopped school bus loading children must you stop?

At least 30 feet. Children getting on or off may cross in front of the bus. Thirty feet gives them room and lets you see them. Class D & E Driver's Guide, p.88: “You must stop at least thirty feet from a stopped school bus that is loading or unloading children.”

What does having the right of way guarantee you?

It does not guarantee your safety. Another driver may not stop when they should. Being in the right does not undo a crash. Class D & E Driver's Guide, p.89: “Having the right of way does not guarantee your safety.”

How far before a turn must you signal and get into the proper lane?

At least 100 feet. Signaling early tells drivers behind you to slow down before you do, so they do not run into you. Class D & E Driver's Guide, p.89: “The law requires that you signal and get into the proper lane at least 100 feet before making a turn.”

When preparing to turn, what comes first?

Signal, then move into the lane. The signal warns the drivers around you before your car moves, so nobody is caught off guard. Class D & E Driver's Guide, p.89: “Signal first and then move into the proper lane.”

Why keep your wheels straight while waiting to turn left?

So a rear-end hit won't push you into traffic. If your wheels point left and someone rear-ends you, your car rolls right into oncoming cars. Class D & E Driver's Guide, p.90: “Keep your wheels straight while waiting to turn.”

You may not turn around on a hill or curve unless other drivers can see your car from how far?

500 feet. A car turning around blocks the road. Drivers coming over a hill need room to see it and stop. Class D & E Driver's Guide, p.90: “Do not attempt to turn around while on a hill or in a curve where your vehicle cannot be seen by other drivers approaching from either direction within 500 feet.”

While you are in a shared center left turn lane, what should you watch for?

Cars pulling out of side streets. Cars leaving driveways and side streets may pull into the same center lane you are in. Class D & E Driver's Guide, p.91: “Watch for vehicles pulling out of entrances and side streets and do not use a shared left turn lane for anything but turning left.”

Which way does traffic travel around a roundabout's center island?

Counterclockwise. If everyone goes the same way around, cars in the circle never meet head-on. Class D & E Driver's Guide, p.91: “Vehicles travel counterclockwise around a raised center island, with entering traffic yielding the right-of-way to circulating traffic.”

When must you give a signal to other drivers?

When you turn, change lanes, slow or stop. Crashes happen when one driver does something the other does not expect. A signal removes the surprise. Class D & E Driver's Guide, p.92: “You must always give a signal to other drivers when you plan to turn, change lanes, slow down or stop.”

What does a driver's left arm held straight out the window mean?

Left turn. Hand signals work when signal lights are broken. Others must read them right away. Class D & E Driver's Guide, p.93: “Arm straight is for a left turn”

What does the right-of-way law actually do?

Says who must yield, but gives it to no one. No driver owns the road. The rules only say who must wait, so everyone still has to watch out. Class D & E Driver's Guide, p.93: “The law says who must yield the right-of-way to another roadway user; it does not give anyone the right-of-way.”

When you must stop at a railroad crossing, what is the farthest from the nearest rail you may stop?

50 feet. Stopping too far back can leave you unable to see the tracks or the signals clearly. Class D & E Driver's Guide, p.94: “Louisiana law R.S. 32:171 requires that the driver of any motor vehicle must stop within 50 feet but no less than 15 feet from the nearest rail of a railroad crossing when:”

What does the large X with two R's painted before a railroad crossing mean for passing?

It is a no passing zone. Passing near a crossing puts you in the wrong lane at the tracks, where you may not see a train or the gate. Class D & E Driver's Guide, p.95: “The pavement is marked with a large “X” and two “R’s”.”

Over whom does a train have the right of way?

Everyone, even police and ambulances. A train cannot stop or turn to miss you, so everyone else must wait for it. Class D & E Driver's Guide, p.96: “Trains have the right of way 100% of the time over emergency vehicles, cars, the police and pedestrians.”

Where is backing up never allowed?

On a controlled-access highway. On a fast highway, cars behind you will not expect a car rolling backward and cannot stop in time. Class D & E Driver's Guide, p.96: “Backing up is not permitted on the shoulder or roadway of any controlled-access highway.”

What is the most people allowed in the front seat of a moving vehicle?

3 people. A crowded front seat gets in the way of the driver's arms and view. Class D & E Driver's Guide, p.96: “It is against the law for more than three persons to occupy the front seat of a moving vehicle.”

A funeral procession is passing through an intersection. What must you do?

Yield to the vehicles in the procession. Breaking into a procession splits up mourners who are following each other and can cause a crash. Class D & E Driver's Guide, p.97: “Funeral processions require all operators of motor vehicles to yield the right-of-way to the vehicles participating in a funeral procession.”

How close may you follow an emergency vehicle responding to a call?

No closer than 500 feet. Fire trucks and ambulances stop and turn without warning. Staying far back keeps you out of their way. Class D & E Driver's Guide, p.97: “Following emergency vehicles responding to call closer than 500 feet is unlawful.”

Which use of headphones while driving does Louisiana allow?

A headphone in 1 ear alone. With both ears covered, you may not hear a siren, a horn or a train in time. Class D & E Driver's Guide, p.97: “Wearing headphones (headset, headphone, or listening device) in one ear alone is allowed.”

Which of these is illegal under Louisiana law?

Lending your license to a friend. A license proves who is driving. Lending or changing it hides who is behind the wheel. Class D & E Driver's Guide, p.97: “It is illegal to lend your driver’s license to another person, to alter your driver’s license in any manner,”

Do traffic laws apply to people riding bicycles?

Yes, the same rules as drivers. A bike is part of traffic. When riders follow the same rules, drivers can predict what they will do. Class D & E Driver's Guide, p.97: “Traffic laws apply to persons riding bicycles.”

Which habit helps you avoid becoming the victim of a staged crash?

Leaving plenty of space ahead. Crooks may slam on the brakes in front of a close car so it hits them and they can claim money. Class D & E Driver's Guide, p.98: “Always give yourself plenty of space between you and the vehicle in front of you.”

Why should you plan your route before driving on an interstate?

Entrances and exits may be far apart. If you do not know your exit, you may pass it with no easy way back for many miles. Class D & E Driver's Guide, p.100: “Since interstate entrances and exits maybe far apart, you should plan your route in advance.”

Unless another limit is posted, what is the maximum speed on a Louisiana interstate?

70 mph. Above this speed a driver has less time to react, and crashes at high speed hurt people far worse. Class D & E Driver's Guide, p.100: “Remember that the maximum speed allowed is 70 miles per hour unless otherwise posted.”

How large a gap do you need when you merge into traffic?

4 seconds. Too small a gap leaves no safe space in front of you or behind you, so do not squeeze into one. Class D & E Driver's Guide, p.101: “When you merge into traffic, you need a gap of four seconds.”

When may you leave the right-hand lane of a two-lane interstate?

To pass, exit left, or let a car enter. Drivers who wander from lane to lane create more chances for a crash with cars they did not see. Class D & E Driver's Guide, p.101: “Stay in the right-hand lane unless overtaking and passing, making an exit to the left, or letting another vehicle enter.”

On the interstate, what is the least space cushion you should keep behind the vehicle ahead?

4 seconds. Drivers slowing for exits can brake suddenly, and a big gap gives you time to stop behind them. Class D & E Driver's Guide, p.101: “Always keep at least a four seconds space cushion between you and the vehicle ahead.”

Which of these is one of the three basic elements of space management?

Lane position. Using all three together keeps room around your car so you have time to see trouble and act. Class D & E Driver's Guide, p.102: “There are three basic elements to space management: 1. Speed control 2. Lane position 3. Communication”

When should you check that you are in the correct lane for your interstate exit?

About a mile before the exit. Getting into place early saves you from cutting across lanes at the last second. Class D & E Driver's Guide, p.102: “Approximately a mile before your exit, check to make sure you are in the correct lane to make the exit.”

What should you do when driving on a gravel or dirt road?

Reduce speed and add following distance. Tires grip loose gravel and dirt poorly, so the car slides farther before it stops. Class D & E Driver's Guide, p.103: “When driving on gravel or dirt, you must reduce your speed and increase your following distance, since it will take much longer to stop due to loss of traction.”

You see a deer cross the road ahead. What should you expect?

Another animal is nearby. Deer and other animals often travel in groups, so a second one may follow the first. Class D & E Driver's Guide, p.104: “If you see one animal, expect there is another nearby.”

A crash with a deer cannot be avoided. What should you do?

Keep control and stay on the road. Swerving off the road can roll your car or hit a tree, which may hurt you more than the animal would. Class D & E Driver's Guide, p.105: “Keep your vehicle under control and on the roadway when you hit the animal.”

A triangle emblem on the back of a farm vehicle means it is traveling slower than what speed?

25 mph. You will close in on such a vehicle very fast, so the emblem warns you to slow down early. Class D & E Driver's Guide, p.105: “A fluorescent or reflective orange and red triangle displayed on the rear of vehicles drawn by animals, farm equipment or construction equipment means the vehicle is traveling less than 25 mph.”

What can happen when you overload your vehicle?

It harms the brakes and suspension. Too much weight makes brakes work harder than they were built for, so the car takes longer to stop. Class D & E Driver's Guide, p.106: “If the vehicle is overloaded it can cause harm to your brakes making it hard for you to stop or slow down and can damage your suspension.”

Which headlights should you use when driving in fog or a heavy downpour?

Low beams. High beams bounce off rain and fog back into your eyes, while low beams light the road and help others see you. Class D & E Driver's Guide, p.106: “When driving in a heavy downpour or in fog, slow down and turn on your low beam headlights.”

At night, when should you use your high beams?

Whenever no vehicles are oncoming. Your headlights limit how far you see at night, so use the brighter beams when no one will be blinded. Class D & E Driver's Guide, p.107: “Use your high beams whenever there are no oncoming vehicles.”

What can happen if you look straight into oncoming headlights?

Brief blindness from glare. Even a second of glare blindness means a second of driving with no idea what is ahead. Class D & E Driver's Guide, p.107: “Avoid looking directly into oncoming headlights as this can cause momentary blindness from the glare.”

What type of road condition do you usually meet in moderate to heavy traffic?

Closed conditions. In heavy traffic your room to move is blocked, so you must plan your speed and path more carefully. Class D & E Driver's Guide, p.107: “You will encounter this type of conditions driving in moderate to heavy traffic.”

What does the manual call the best way to extend your vehicle's life and save fuel?

Use it as little as possible. Every trip you skip saves gas and wear, and takes one more car off a crowded road. Class D & E Driver's Guide, p.108: “The best way to extend the life of your vehicle and save on fuel is to use it as little as possible.”

On major highways, about how many miles does the average driver cover every two hours?

100 to 110 miles. Knowing a realistic pace helps you plan stops and avoid rushing to keep a schedule. Class D & E Driver's Guide, p.108: “The average number of miles driven on major highways is 100 to 110 miles every two hours with 10 to 15 minute breaks every 2 to 3 hours and 1 hour stops for meals.”

Which of these is one of the three main types of distraction?

Cognitive. Each type pulls a different part of you off driving: your eyes, your hands or your mind. Class D & E Driver's Guide, p.110: “Three main types of distraction:”

Under Louisiana law, drivers of what age or younger may not use a wireless device for calls or texts while driving?

17 years old. Teens are the highest-risk group for texting crashes, so the law takes the phone out of their hands. Class D & E Driver's Guide, p.111: “Louisiana laws state no person who is seventeen years of age or younger shall operate a motor vehicle on any public road or highway in this state while using any wireless telecommunications device to engage in a call or write, send or read a text-based communication.”

Your phone slides onto the floor while you drive. What should you do?

Leave it until you stop. Reaching down takes your eyes, hands and mind off the road at once. Class D & E Driver's Guide, p.111: “Do not try to retrieve items that fall on the floor or elsewhere in the car.”

Speeding, tailgating and failure to signal fall under which collision factor?

Driver behavior. Most of these you cannot control, but how you drive is the one you can always change. Class D & E Driver's Guide, p.112: “4. Driver Behavior – speeding, tailgating, aggressive driving, unsafe lane changing, failure to signal, and failure to give the right of way.”

Without anti-lock brakes, why should you not brake hard and hold in an emergency?

It locks the wheels into a skid. Locked wheels slide instead of roll, and a sliding car cannot be steered. Class D & E Driver's Guide, p.113: “If you have a manual (disc) brake system, do not brake hard and hold.”

If you must leave the road to avoid a crash, what should you try to hit?

Brush or shrubs. Bushes absorb a crash slowly, while a tree or wall stops the car and the people in it all at once. Class D & E Driver's Guide, p.113: “Choose to hit something that will give way (such as brush or shrubs) rather than something hard.”

What is the best protection before a crash?

Your seat belt and harness. Many crashes happen close to home, so a belt only helps if it is on every time. Class D & E Driver's Guide, p.114: “The best protection before a crash is to always buckle your seat belt and shoulder harness before you start any trip in your vehicle no matter how short your journey will be.”

Why are SUVs and pickups more likely to roll over than cars?

Their higher center of gravity. A tall vehicle is top heavy, so a sharp turn or bump can tip it over more easily. Class D & E Driver's Guide, p.114: “Rollover crashes are more common for sport utility vehicles (SUVs), vans, pickups and small trucks than for passenger vehicles due to their higher centers of gravity, which makes them top heavy and more likely to tip over.”

The rear of your car starts to slide. What should you do?

Steer the way the rear slides. Braking in a slide locks the wheels, while steering with the slide lets the tires grip again. Class D & E Driver's Guide, p.115: “If the rear of your car starts to slide, don’t use your brakes.”

On a wet road, where does the manual suggest you drive?

In the tire tracks of cars ahead. Those tracks have less standing water, so your tires keep better contact with the road. Class D & E Driver's Guide, p.116: “Try to drive in the tire tracks left by the cars in front of you.”

With your wheels off the pavement, how should you slow down?

By gently using your brakes. Gentle braking slows you while keeping the car steady on loose ground. Class D & E Driver's Guide, p.116: “1. Slow down by gently using your brakes.”

Your car stalls on the tracks with no train in sight. When may you try to move it off?

Only if you are certain there is time. Moving the car is only worth trying when you are sure no train will arrive first. Class D & E Driver's Guide, p.116: “If danger is not immediate, and you are certain there is time, you may move your vehicle off the tracks.”

What is the most important rule when a tire blows out?

Don't panic or slam the brakes. Hard braking with a blown tire can pull the car sharply to one side and out of control. Class D & E Driver's Guide, p.117: “The most important rule is - don’t panic and don’t slam on the brakes.”

Your gas pedal sticks while driving. What should you do first?

Shift into neutral. Neutral cuts the engine's power from the wheels, so the car stops speeding up. Class D & E Driver's Guide, p.117: “If your gas pedal sticks, keep your eyes on the road:”

Your brakes fail. What should you not do?

Yank on the parking brake. A sudden pull on the parking brake can lock the rear wheels and spin the car. Class D & E Driver's Guide, p.117: “Do not put your parking brake on suddenly.”

Steam is coming from under your hood. What should you do?

Pull over and turn off the engine. Steam means the cooling system is boiling, and running the engine longer can ruin it. Class D & E Driver's Guide, p.117: “You should pull to the side of the road and turn off the engine.”

Smoke comes from under the hood. After pulling off the road, what should you turn off?

The engine and all switches. Shutting off power stops fuel and electricity from feeding the fire. Class D & E Driver's Guide, p.117: “2. Turn off the engine and all electrical switches.”

When jump-starting a car, what do you connect the dead battery's positive post to?

The live battery's positive post. Matching positive to positive keeps current from flowing the wrong way and damaging the batteries. Class D & E Driver's Guide, p.118: “3. Connect the positive post of the dead battery to the positive post of the live battery.”

At the first sign of car trouble while driving, what should you do?

Ease off the gas. Braking hard on a busy road can get you hit from behind before you reach the shoulder. Class D & E Driver's Guide, p.118: “At the first sign of car trouble, gently and smoothly take your foot off the accelerator.”

Why is carbon monoxide so dangerous in a car?

It has no odor. You cannot smell the danger, so you have to watch for how you feel instead. Class D & E Driver's Guide, p.119: “Because carbon monoxide does not have an odor, you can be affected without knowing it.”

You see a flooded road ahead. What should you do?

Turn around, use another route. Water can hide a washed-out road, and even shallow moving water can sweep a car away. Class D & E Driver's Guide, p.119: “If you see a flooded roadway ahead, turn around and find another route to get to your destination.”

If your car goes into water, about how long will it float on the surface?

30 to 60 seconds. Those first seconds are your best chance to escape before water pressure holds the doors shut. Class D & E Driver's Guide, p.119: “If your vehicle enters water, it will only float on the surface for 30 to 60 seconds so make every attempt to get out of the vehicle immediately.”

After a crash you are not sure whether anyone needs an ambulance. What should you do?

Assume one is needed and call. Some injuries do not show at first, and waiting can cost a hurt person precious time. Class D & E Driver's Guide, p.120: “If in doubt, assume that an ambulance is needed.”

An injured person at a crash is bleeding. What should you do?

Place a clean cloth over it. Pressure from a clean cloth slows the blood loss until trained help arrives. Class D & E Driver's Guide, p.120: “To stop bleeding, place a clean cloth over the wound.”
