Tennessee Permit Practice Test — Written Test, 30 Questions

Free 10-question Tennessee permit practice test, then full 30-question tests like the real exam, in 4 parts, each question cited to the Tennessee manual.

The exam

The Tennessee Department of Safety and Homeland Security knowledge test is 30 questions and 24 right is a pass. Everything on it comes out of Tennessee Comprehensive Driver License Manual. Officially it is the knowledge test; most people call it the written test, or the permit test.

Tennessee does not state the score that passes its knowledge test directly: 24 of 30 follows from what it does state (the Tennessee Department of Safety and Homeland Security's own knowledge-test page, tn.gov: “The test consists of 30 questions.” The 24 is 80% of it, the rate the same page states).

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 Tennessee 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 Tennessee Comprehensive Driver License Manual, with the page it is on. When the manual does not say, the answer says so rather than guess. Or tick Nationwide and compare every state on one question.

Questions from the Tennessee test

What should you look for when you check around the outside of your vehicle before driving?

Small children, pets and other obstructions. A toddler or a dog sitting behind the car is too low to see from the driver's seat. Tennessee Comprehensive Driver License Manual, p.27: “Check around the outside of the vehicle. Look for small children, pets and any other sort of obstruction.”

How high should the seat head restraint be set?

Level with the back of your head. A head restraint set too low lets your head snap back over it when you are hit from behind. Tennessee Comprehensive Driver License Manual, p.27: “Properly adjust seat head restraints to a level even with the back of the head.”

When should you adjust your mirrors?

After the seat is adjusted, before driving. Moving the seat moves your eyes, so mirrors set first will point at the wrong spot. Tennessee Comprehensive Driver License Manual, p.27: “Adjust mirrors after the seat is adjusted correctly.”

When should you make sure your passengers are buckled up?

Before you start driving. An unbuckled passenger becomes a flying object in a crash and can hurt everyone else in the car. Tennessee Comprehensive Driver License Manual, p.28: “Make sure all passengers are using safety belts or child restraints before driving.”

Before starting a car with an automatic transmission, what gear should it be in?

PARK (P). Start a car that is in gear and it can lurch into whatever is in front of it. Tennessee Comprehensive Driver License Manual, p.28: “Place foot on brake pedal and ensure gearshift selector is in the PARK position for automatic transmissions or in NEUTRAL for manual/standard transmissions.”

When are the lower gears (L, 2 or 1) of an automatic transmission used?

On steep downgrades or icy roads. Low gear lets the engine hold the car back, so the brakes do not overheat on a long hill. Tennessee Comprehensive Driver License Manual, p.28: “These gears are generally not used except for special or emergency situations, such as:”

How many hands should you keep on the steering wheel while driving?

Both hands, at all times. With one hand on the wheel, a sudden swerve or a blown tire can pull the car out of your control. Tennessee Comprehensive Driver License Manual, p.28: “To begin driving the vehicle, use a relaxed grip on the steering wheel and always drive with BOTH hands on the wheel.”

Which is a common mistake new drivers make when backing up?

Moving too fast. In reverse, small wheel moves swing the car a lot, so too much speed or steering puts you into a pole. Tennessee Comprehensive Driver License Manual, p.29: “Common mistakes committed by new drivers when backing are (a) moving too fast, (b) providing too much steering input and (c) turning the steering wheel in the wrong direction.”

Why is carbon monoxide from a car engine so dangerous?

It can kill, and you cannot see or smell it. You get no warning: you just feel sleepy or sick, and you may not notice in time. Tennessee Comprehensive Driver License Manual, p.29: “Carbon monoxide gas from a car engine can kill (it has not taste, no smell or visibility).”

Under Tennessee's hands-free law, may a driver hold a phone in their hand?

No, not with any part of the body. A phone in your hand, even at your ear, takes a hand off the wheel and your mind off the road. Tennessee Comprehensive Driver License Manual, p.30: “hold a cellphone or mobile device with any part of their body,”

Who must wear a safety belt any time the vehicle is in motion?

All drivers and all front-seat passengers. A short trip to the store is when many crashes happen, so the belt goes on every time the car moves. Tennessee Comprehensive Driver License Manual, p.31: “Safety belts are required for ALL drivers and all passengers in the FRONT seat, any time the vehicle is in motion.”

A child under 1 year old must ride in what kind of car seat?

A rear-facing car seat. A baby's neck is too weak to hold its head in a crash. Facing the rear, the seat back takes the hit. Tennessee Comprehensive Driver License Manual, p.31: “A child under one year old, or any child weighing less than 20 pounds, must be in a child passenger restraint system (car seat) that is facing the rear of the car.”

What do safety belts virtually eliminate in a crash?

Being ejected from the vehicle. Thrown from the car, you hit the pavement or land in the path of another vehicle. Tennessee Comprehensive Driver License Manual, p.31: “Safety belts virtually eliminate ejection.”

About how long does it take to undo a safety belt?

Less than 1 second. Fearing being trapped is no reason to skip the belt. Unbuckling is faster than opening the door. Tennessee Comprehensive Driver License Manual, p.32: “It takes less than a second to undo a safety belt.”

A child is ready to use the adult lap and shoulder belt when they can do what?

Sit back, knees bent over the edge. If the knees cannot bend at the edge, the child slouches and the belt rides up onto the stomach. Tennessee Comprehensive Driver License Manual, p.33: “Basically, a child is big enough to use the vehicle lap and shoulder belt when (1) they can sit with their back against the vehicle seat back and (2) their knees bend over the edge of the vehicle seat.”

What is the age limit below which no child may ride in the bed of a pickup truck anywhere in Tennessee?

Under 6 years old. Nothing holds a child in a truck bed. A bump or a sudden stop can toss them onto the road. Tennessee Comprehensive Driver License Manual, p.33: “It is illegal in Tennessee to allow any child under the age of 6 to ride in the bed of a pickup truck.”

What gives the best protection currently available in a car?

Air bags combined with safety belts. An unbelted person slides forward into the air bag as it bursts out, which is when it hurts the most. Tennessee Comprehensive Driver License Manual, p.33: “Air bags combined with safety belts are the best protection currently available in a car, SUV, or truck.”

What is the age limit below which leaving a child alone in a vehicle in a public place can be an offense?

Younger than 7. A small child alone in a car can overheat, knock it into gear, or be taken along with the car. Tennessee Comprehensive Driver License Manual, p.33: “It is an offense for a person responsible for a child younger than 7 years of age to knowingly leave that child in a motor vehicle located on public property or while on the premises of any shopping center, trailer park, or any apartment house complex, or any other premises that is generally frequented by the public at large without being supervised in the motor vehicle by a person who is at least 13 years of age, if:”

A crossing guard waves you to stop while your light is green. What must you do?

Stop, because the guard's direction comes first. A signal cannot see a crash or a child in the road, but the person directing traffic can. Going on the light can put you into what they are stopping you for. Tennessee Comprehensive Driver License Manual, p.35: “Drivers must obey directions from these individuals, even if the directions are different than what the traffic lights and signs indicate.”

What kind of sign uses an orange background?

Construction and maintenance signs. Orange tells you workers or machines may be close to your lane. Spotting it early gives you time to slow before you reach them. Tennessee Comprehensive Driver License Manual, p.35: “ORANGE is used as a background color for construction and maintenance signs and shall not be used for any other purpose.”

What shape is a regulatory sign, such as a speed limit sign?

A rectangle. Knowing the shape lets you tell a law from a warning even before you can read the words. Tennessee Comprehensive Driver License Manual, p.35: “For example, a regulatory sign is always a rectangle, telling you about laws and regulations or giving you instructions such as speed limits or lane uses.”

Besides school zones, where are fluorescent yellow-green signs used?

At pedestrian areas such as crosswalks. These signs mean people on foot are likely near. A walker stepping into a crosswalk has no protection from your car. Tennessee Comprehensive Driver License Manual, p.36: “FLUORESCENT YELLOW-GREEN is now in use for signage in school zones and other pedestrian traffic areas such as crosswalks.”

What must you do at this sign?

Stop fully, before the crosswalk. Rolling past the crosswalk puts your bumper where people walk. It also pokes your car into cross traffic. Tennessee Comprehensive Driver License Manual, p.36: “It tells you that you are approaching an important street or highway and that you must bring your car to a complete stop, not going beyond the crosswalk.”

What does an ALL WAY plate under a stop sign mean?

Every road into the corner must stop. With the plate, every driver stops. Without knowing that, you might wait forever for cross traffic you think has the road. Tennessee Comprehensive Driver License Manual, p.36: “It means all traffic approaching this intersection must stop.”

What must you do when you see this sign?

Slow down and be ready to stop. A train cannot stop or swerve for you. Slowing early gives you room to stop short of the tracks. Tennessee Comprehensive Driver License Manual, p.36: “You must slow down and be ready to stop.”

What does the small sign under a crossbuck tell you?

How many tracks there are. With two or more tracks, one train passing can hide a second train coming the other way. Tennessee Comprehensive Driver License Manual, p.36: “They show the number of tracks at a particular crossing.”

What does this sign mean?

A crossroad is ahead. Cars can come at you from both sides at a crossroad. Knowing it is coming lets you slow and look left and right. Tennessee Comprehensive Driver License Manual, p.36: “This sign tells you it is a crossroad.”

What does this sign tell you?

A stop sign is ahead out of view. A hill or curve can hide the stop sign until you are close. Slowing now keeps you from sliding past it. Tennessee Comprehensive Driver License Manual, p.38: “This sign indicates that there is a STOP sign just ahead that you cannot yet see.”

On a multi-lane highway with a SLOWER TRAFFIC KEEP RIGHT sign, where should you drive?

In the far right lane. Slow cars in the left lane force faster drivers to weave around them. That weaving is where crashes start. Tennessee Comprehensive Driver License Manual, p.37: “It means that you must drive in the extreme right lane unless you want to pass a slower moving car or make a left turn.”

What does this sign mean?

You may not pass here. Passing here means driving in the lane of oncoming cars where you cannot see far enough ahead. Tennessee Comprehensive Driver License Manual, p.37: “No Passing Signs: These signs tell you where passing is not permitted.”

What do warning signs alert you to?

Conditions that may call for slowing. A warning sign tells you about trouble before you can see it. Waiting to see it yourself leaves you too little time. Tennessee Comprehensive Driver License Manual, p.38: “Warning signs alert road users to conditions that might call for a reduction of speed or an action in the interest of safety and efficient traffic operations.”

Where should you look when you see a FALLEN ROCK sign?

At the road ahead. Staring up at the cliff takes your eyes off the rock lying in your lane around the curve. Tennessee Comprehensive Driver License Manual, p.38: “This sign warns of rocks that may be in the road, not of rocks which may strike you from overhead.”

What do orange work area signs warn you about?

People working on or near the road. Workers stand a few feet from moving cars. Orange signs tell you to slow before you reach them. Tennessee Comprehensive Driver License Manual, p.39: “These construction, maintenance or emergency operations signs are generally diamond or rectangular shaped, orange with black letters or symbols and warn you that people are working on or near the roadway.”

What do flaggers at most worksites hold?

A paddle reading STOP and SLOW. The paddle side you see is your order. Reading SLOW as GO can send you into the work area too fast. Tennessee Comprehensive Driver License Manual, p.39: “Flaggers, at most worksites, will be using paddles with the word stop on one side and slow on the other.”

On which vehicle would you expect to see a slow-moving vehicle emblem?

A farm tractor. These vehicles often go less than 25 mph. Coming up on one at highway speed leaves very little time to brake. Tennessee Comprehensive Driver License Manual, p.40: “You may see this emblem on slow-moving vehicles, such as farm tractors, machinery, construction equipment or horsedrawn vehicles.”

What does an object marker warn you of?

An object near the road's edge. A bridge end or post just off the edge can tear a car apart. The striped marker shows you where it is. Tennessee Comprehensive Driver License Manual, p.40: “These markers warn you of objects, not actually in the roadway, but so close to the edge of the road that need marking.”

What does a blue and red route marker show?

An interstate. Interstate markers help you follow a long route across states. Mistaking one for a local road can send you far off track. Tennessee Comprehensive Driver License Manual, p.40: “Blue and red signs, like the one on the right, indicate that the route is part of the national system of interstate and defense highways.”

What does this sign help you choose?

Your lane and exit. These signs come up fast at highway speed. Reading them early lets you move over before your exit, not at it. Tennessee Comprehensive Driver License Manual, p.40: “Such signs give information vital to selection of lane, proper exits, etc.”

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

The red lamp. Knowing the order helps when the sun glares on the lens. You can tell which lamp is lit by where it sits. Tennessee Comprehensive Driver License Manual, p.41: “Standard traffic lights are red, yellow and green, from top to bottom respectively.”

What does a green turn arrow give you?

The right-of-way to turn that way. The arrow holds oncoming cars so you can turn. A late walker may still be crossing, so look before you go. Tennessee Comprehensive Driver License Manual, p.41: “When the arrow is green, you have the right-of-way and may drive the vehicle only in the direction of the arrow, after yielding to vehicles and pedestrians already in the intersection.”

The traffic light at an intersection is out. How must you treat it?

As an all-way stop. A dark signal gives no one the right-of-way. Treating it as a green for you is how drivers collide in the middle. Tennessee Comprehensive Driver License Manual, p.41: “Tennessee state law requires that if a signal is not working, the intersection is to be treated as if it were a ll-way stop intersection.”

What does a pedestrian signal showing a walking person mean?

It is safe for walkers to cross. When you see WALK on the corner, expect people to step into the crosswalk across your path. Tennessee Comprehensive Driver License Manual, p.42: “The displays the word “WALK” or a symbol of a person walking when it is safe to cross the street or intersection.”

Where are lane control signals most often used?

Where lane direction changes by time of day. A lane that carries you to work in the morning may carry cars toward you at night. The signal tells you which way it runs now. Tennessee Comprehensive Driver License Manual, p.42: “They are most often used when the direction of the flow of traffic changes during different hours of the day.”

Which line marks the right edge of the traffic lane?

A solid white line. Knowing which edge is which keeps you on your own side of the road at night, when the lines are all you can see. Tennessee Comprehensive Driver License Manual, p.42: “A solid white line indicates the right edge of the traffic lane on a road.”

What color are the lines that separate traffic moving in opposite directions?

Yellow lines. A yellow line means cars on the other side are coming toward you. Crossing it carelessly risks a head-on crash. Tennessee Comprehensive Driver License Manual, p.42: “A. Yellow Lane Markings: Lines separating traffic moving in opposite directions are yellow.”

What do white lane markings between lanes tell you?

Traffic moves the same way. White lines mean the cars beside you go your way. That tells you the road is one-way or divided. Tennessee Comprehensive Driver License Manual, p.43: “White Lane Markings - Multiple lanes of traffic that flow in the same direction are separated by white lane markings.”

Besides intersections, where may a crosswalk be?

In the middle of a block. A mid-block crosswalk can catch you off guard. A walker there expects you to stop just as at a corner. Tennessee Comprehensive Driver License Manual, p.43: “Crosswalks define the area where pedestrians may cross the roadway and may be located at intersections or in the middle of a block.”

What pavement marking shows an HOV lane?

A diamond in the lane. The diamond tells you the lane has rules about who may use it. Driving alone in it at the wrong time can get you a ticket. Tennessee Comprehensive Driver License Manual, p.43: “High Occupancy Vehicle (HOV) Lanes are designated on highways by a diamond-shaped marking in the center of the lane.”

Which way do you go around a traffic circle or town square in Tennessee?

To the right. Every driver coming into a circle expects cars to flow one way. Going the other way puts you head-on with them. Tennessee Comprehensive Driver License Manual, p.45: “This means we drive on the right side of the road, and turn right when going around traffic circles, roundabouts or town squares.”

Your headlights must be on from how long after sunset until the same time before sunrise?

30 minutes. Dusk and dawn are dim enough that a dark car blends into the road. Lights on in that half hour let others see you coming. Tennessee Comprehensive Driver License Manual, p.45: “Required Night Use: Your car headlights must be turned on 30 minutes after sunset until 30 minutes before sunrise.”

Your car is stopped on the shoulder in thick fog. What does the law require?

Your parking lights must be on. In fog, a dark car sitting on the shoulder is almost invisible. A driver can drift onto the shoulder and hit it from behind. Tennessee Comprehensive Driver License Manual, p.45: “The law requires a vehicle stopped or parked on a road or shoulder to have parking lights on when limited visibility conditions exist.”

What colors may steady-burning lights on the front of a car in Tennessee be?

White or amber. Drivers read light colors fast. A red or blue light on the front of a car can be mistaken for a police car or a stop signal. Tennessee Comprehensive Driver License Manual, p.45: “Effective January 1, 2018, no vehicle operated in Tennessee shall be equipped with any steady-burning lights that display to the front of the vehicle in any color other than white or amber or in any combination of colors other than white and amber.”

How must a vehicle carry litter or a load that could blow onto the highway?

Enclosed or fully covered by a tarp. Trash or gravel blowing out of a truck bed can hit the windshield behind it. The driver may swerve into another lane. Tennessee Comprehensive Driver License Manual, p.46: “Tennessee law requires any motor vehicle transporting litter or any material, likely to fall or be blown off onto the highway, to be in an enclosed space or fully covered by a tarpaulin.”

When is it illegal to drive slower than the posted minimum speed?

Under normal driving conditions. Cars coming up fast behind a slow car have to brake hard or swerve. That is how rear-end crashes start. Tennessee Comprehensive Driver License Manual, p.46: “It is against the law to drive slower than the posted minimum speed under normal driving conditions.”

What do oncoming Tennessee drivers commonly do when they meet a funeral procession?

Pull to the side of the road. Families in a funeral line notice who slows and pulls over. It is a small kindness that Tennessee drivers expect of each other. Tennessee Comprehensive Driver License Manual, p.46: “In Tennessee, it is a common and accepted practice for oncoming traffic to pull to the side of the roadway as a sign of respect when meeting a funeral precession.”

Under the Basic Speed Rule, what limits the speed you may drive?

The conditions you are driving in. A 65 mph limit is set for a dry road in daylight. On a dark two-lane road in rain, that speed leaves no time to stop. Tennessee Comprehensive Driver License Manual, p.46: “The BSR does not set an exact speed limit; instead, it teaches that the speed you may drive is limited by current conditions.”

Unless a sign says otherwise, what is the speed limit on Tennessee's state and federal highways?

55 mph. Most open roads are not posted at every mile. The 55 mph default tells you the limit when no sign is in sight. Tennessee Comprehensive Driver License Manual, p.47: “Unless otherwise posted, the speed limit on primary and secondary state and federal highways is 55 m.p.h.”

What is the maximum speed set by Tennessee law for interstate highways?

70 mph. Even on the fastest roads there is a ceiling. Above 70 mph, stopping distances grow longer than most drivers expect. Tennessee Comprehensive Driver License Manual, p.47: “The maximum speed set by Tennessee law for interstate highways is 70 m.p.h.”

How can you recognize a highway work zone?

Orange signs and traffic devices. Workers stand a few feet from moving cars. Spotting the zone early gives you time to slow down before you reach them. Tennessee Comprehensive Driver License Manual, p.47: “Highway work zones are easily recognized by the presence of orange (or yellow-green) signs and other orange traffic control devices, flashing lights on equipment and workers dressed in highly visible clothing (orange or yellow-green).”

By law, how many separate ways of applying the brakes must every automobile have?

2 methods. If one brake system fails, the other is your only way to stop. The law makes sure every car has a backup. Tennessee Comprehensive Driver License Manual, p.48: “By law, all automobiles must have two separate methods of applying brakes.”

How should you press the brake in a car with anti-lock brakes (ABS)?

With firm, steady pressure. ABS pumps the brakes for you, many times a second. Pumping the pedal yourself turns the system off and can lock the wheels. Tennessee Comprehensive Driver License Manual, p.48: “When slowing or stopping, apply firm, steady pressure to the brake pedal.”

What does 'covering the brake' mean?

Holding your foot just over the brake. Near parked cars or a school, a child can step out at any moment. A foot already over the brake saves precious time. Tennessee Comprehensive Driver License Manual, p.48: “In situations listed above, “covering the brake” means the driver’s foot needs to hover over the brake or between the brake and gas pedals for quicker response time.”

Under Tennessee law, how closely may you follow another vehicle?

No closer than is reasonable and prudent. There is no single safe gap for every road. On wet roads or at high speed, you need more room to stop. Tennessee Comprehensive Driver License Manual, p.48: “Tennessee law states: “The driver of a motor vehicle shall not follow another vehicle more closely than is reasonable and prudent, having due regard for the speed of such vehicles and the traffic upon and the condition of the highway.”

How do you check your following distance with the two-second rule?

Count seconds after the car ahead passes a fixed point. Guessing a gap in feet is hard at speed. Counting seconds works the same at any speed and needs no tools. Tennessee Comprehensive Driver License Manual, p.48: “As the car ahead of you passes a stationary point on the road (a sign post, driveway, utility pole, etc.), count the seconds it takes you to reach the same spot.”

What does a sudden stop usually show about a driver?

They were not paying attention. Good drivers see a stop coming well ahead. A panic stop usually means something was missed, and the car behind may not stop. Tennessee Comprehensive Driver License Manual, p.49: “Stopping suddenly is dangerous and usually indicates that a driver was not paying attention, was speeding or was not allowing a safe following distance.”

How does Tennessee Code define a stop?

Complete cessation of movement. A car still creeping forward can still hit someone. Only a full stop counts under the law. Tennessee Comprehensive Driver License Manual, p.49: “Tennessee Code defines “stop” as “complete cessation of movement.”

When stopped behind another car, how much gap should you leave?

Enough to see its back tires. If the car ahead rolls back or stalls, the gap lets you steer around it. Without it you are boxed in. Tennessee Comprehensive Driver License Manual, p.50: “A basic rule of thumb is that you should be able to see the license plate and/or the other vehicle’s back tire where it meets the pavement.”

Which marking is painted on the road before a railroad crossing?

A large X with the letters RR. The marks on the road warn you even when the sign is hidden. Seeing them early gives you time to slow down. Tennessee Comprehensive Driver License Manual, p.50: “Railroad crossings have pavement markings that include a large crossbuck (“X”), the letters “RR”, a no-passing zone stripe and a stop line.”

Must an empty school bus stop at a railroad crossing?

Yes, even with no passengers aboard. A bus ahead may stop at the tracks with no signal flashing. If you are not ready, you will rear-end it. Tennessee Comprehensive Driver License Manual, p.51: “Church or school buses, regardless of whether such buses are carrying any passengers at the time of crossing;”

A school bus is stopped at an intersection to load children. Which drivers must stop?

Drivers from all directions. Children leaving a bus may cross in any direction. A car turning in from the side street can hit them as easily as one from behind. Tennessee Comprehensive Driver License Manual, p.51: “When a school bus is stopped at an intersection to load and unload children, drivers from ALL directions are required to stop until the bus resumes motion (as shown by the red vehicles in the diagram at right).”

How will a police vehicle signal you to stop?

Flashing blue or blue and red lights. Knowing the signal tells you a stop is real. You can pull over calmly instead of guessing. Tennessee Comprehensive Driver License Manual, p.52: “Police vehicles attempting to stop drivers will do so by means of a visual, flashing blue or flashing blue and red lights, and/or an audible signal.”

Under the left-right-left rule, which way do you look first at an intersection?

To the left. Cars from the left reach your path first, since they are in the near lane. That is the danger to check first. Tennessee Comprehensive Driver License Manual, p.52: “Look first to the left to make sure cross traffic is yielding the right-of-way.”

What does the law say about the right-of-way?

It says only who must yield it. Drivers who think they own the road push ahead into crashes. You must still do everything you can to avoid one. Tennessee Comprehensive Driver License Manual, p.53: “It only says who must yield the right-of-way.”

Under Tennessee law, who counts as a pedestrian?

A person on foot or in a wheelchair. A person in a power chair crossing the street has the same rights as someone walking. Treat them the same. Tennessee Comprehensive Driver License Manual, p.53: “Pedestrian means any person afoot or using a motorized or non-motorized wheelchair.”

When turning left, which oncoming traffic must you wait for?

Cars going straight or turning right. Left turns cut across the path of cars coming at you. Misjudging their speed is a classic cause of serious crashes. Tennessee Comprehensive Driver License Manual, p.53: “When turning left, you must wait for oncoming traffic going straight ahead or turning right.”

At a T intersection, who must yield?

Drivers on the road that ends. Cars on the through road do not expect to stop. The driver on the dead-end road is the one who must wait. Tennessee Comprehensive Driver License Manual, p.54: “At “T” intersections where one road dead-ends into another main crossing roadway, the vehicles on the road ending must yield to oncoming traffic from both directions on the main road;”

An ambulance with its siren on is coming. What must you do?

Pull to the right edge and stop. An ambulance needs a clear lane fast. Cars pulling right and stopping open that lane for it. Tennessee Comprehensive Driver License Manual, p.54: “Tennessee law requires that when an emergency vehicle is approaching, all traffic meeting or being overtaken must yield the right-of-way and immediately drive to a position parallel to, and as close as possible to the right hand edge or curb of the roadway stop.”

A city bus has signaled and is pulling out from a bus stop. What must you do?

Yield and let it pull out. A city bus cannot wait forever for a gap. Letting it pull out keeps the bus on time and you out of its path. Tennessee Comprehensive Driver License Manual, p.54: “You must yield the right-of-way to any transit vehicle (metro bus) that has signaled and is pulling back onto the roadway from a bus stop.”

If you turn without signaling, what do other drivers expect you to do?

Keep going in your lane. Other drivers plan their moves around yours. A turn with no signal catches them by surprise. Tennessee Comprehensive Driver License Manual, p.55: “Unless you signal, other drivers expect you to keep traveling the path of the roadway, using the lane in which your vehicle is positioned.”

How far before a turn must you turn on your signal?

At least 50 feet. Drivers behind need a few seconds of warning to slow down. A late signal is almost no signal at all. Tennessee Comprehensive Driver License Manual, p.56: “At least 50 feet before the turn, you must turn on your turn signal lights.”

What is the first rule of turning?

Closest lane to the closest legal lane. Swinging across lanes in a turn cuts in front of other cars. Going lane to nearest lane keeps you out of their way. Tennessee Comprehensive Driver License Manual, p.55: “The first rule of turning is to turn from the closest lane in the direction you are traveling to the closest legal lane in the direction you want to go.”

You and an oncoming driver both want to turn left. How do you pass each other?

Each turns to the left of the other. Passing left side to left side keeps the two turning cars from meeting nose to nose in the middle. Tennessee Comprehensive Driver License Manual, p.56: “When you meet another driver at an intersection and both of you want to turn left, each will turn to the left of the other.”

When may a car in the second lane make the same turn as a car in the first turn lane?

When a lane use sign or marking permits it. Two lanes turning at once can sideswipe each other. The sign or arrow tells you the second lane is built to turn too. Tennessee Comprehensive Driver License Manual, p.58: “A vehicle in the second lane can make the same turn as a vehicle in the first lane only when a lane use control sign or marking permits it.”

Well ahead of a right turn, where should you position your car?

As close as practical to the right curb. If you turn from the middle of the lane, a bike or car can slip in on your right and you turn across it. Tennessee Comprehensive Driver License Manual, p.58: “Get as close as is practical to the right curb or road edge without interfering with pedestrians, bicyclists or parked vehicles.”

Why might a large truck leave an open space on its right just before a turn?

It must make a wide turn. That gap on a truck's right looks like room to pass, but the trailer is about to sweep through it. Tennessee Comprehensive Driver License Manual, p.58: “Large trucks and buses MUST make wide turns.”

Where is a left turn on a red light allowed in Tennessee?

From a one-way street onto another one-way street. Turning left on red onto a two-way street sends you across lanes of moving cars. Tennessee Comprehensive Driver License Manual, p.58: “A left turn at a red light or stop signal is permitted at all intersections where a one-way street intersects with another one-way street and the traffic is moving in the same direction into which the left turn would be made.”

What is a roundabout?

An intersection where traffic circles a central island. Knowing it is an intersection reminds you to slow down and yield, not to drive through it like an open road. Tennessee Comprehensive Driver License Manual, p.58: “A roundabout is an intersection control device with traffic circulating around a central island.”

Where is a U-turn not allowed?

At an intersection run by a traffic light or officer. Drivers moving on a green or an officer's wave do not expect a car swinging around in front of them. Tennessee Comprehensive Driver License Manual, p.59: “At any intersection where a traffic light or police officer is controlling the traffic flow.”

On a road with no center line, how much room must you give oncoming drivers?

At least half of the road. On a gravel or parking-lot road with no lines, a car that hugs the middle meets the next car head-on. Tennessee Comprehensive Driver License Manual, p.59: “When driving on a road without any center line markings, and where vehicles are coming from each direction, drivers must give others going in the opposite direction at least half the road.”

What do red reflectors facing you on the lane lines mean?

You are facing traffic the wrong way. At night the reflectors may be your only warning before headlights come straight at you. Tennessee Comprehensive Driver License Manual, p.60: “Red reflectors always mean you are facing traffic the wrong way and could have a head-on collision.”

When you use a crossover on a divided four-lane highway, where do you keep?

To the right side of the crossover. A car from the other side may be turning into the same opening. Keeping right keeps you out of its path. Tennessee Comprehensive Driver License Manual, p.60: “treat the crossover/opening the same as a cross street by keeping to the right side of the crossover paved area.”

A lane has both a turn arrow and a straight arrow. What may you do from it?

Go straight or make the turn shown. Drivers beside you may also be turning or going straight, so read the arrows before you choose. Tennessee Comprehensive Driver License Manual, p.60: “You can proceed straight or make the indicated turn from these lanes as shown by the pavement markings and/or signs found at the intersection.”

How are reversible lanes usually marked?

Double-broken yellow lines. The lane you drove in this morning may carry oncoming cars this evening. Tennessee Comprehensive Driver License Manual, p.61: “These lanes are called “reversible lanes” and are usually marked by double-broken yellow lines.”

When may a regular car use a lane reserved for buses?

When turning across it within half a block. A car parked in the bus lane holds up a whole bus of riders behind it. Tennessee Comprehensive Driver License Manual, p.61: “Do NOT travel in one of these lanes unless operating the type of vehicle indicated, or unless you must turn across the reserved lane in the next half block distance.”

Where should you avoid riding along on a multi-lane road?

In the blind spot of a car ahead. The driver ahead cannot see you there and may change lanes right into your car. Tennessee Comprehensive Driver License Manual, p.61: “Do not cruise in the blind spots of any vehicles ahead of you.”

What risk do you take if you cut back into your lane too soon after passing?

Sideswiping the car you just passed. A pass begun without room ends with you squeezed between the car you are passing and oncoming traffic. Tennessee Comprehensive Driver License Manual, p.61: “If you have to cut back to your lane too soon, you risk sideswiping the vehicle you are passing.”

May you pass on the right by driving off the pavement?

No, that is never permitted. Drivers ahead do not look for a car on the shoulder and may turn or pull off right into it. Tennessee Comprehensive Driver License Manual, p.62: “Passing on the right is never permitted by driving off the pavement of the roadway.”

What does the end of a no-passing zone tell you?

There is more visibility ahead. The sign tells you the road has opened up. You still have to check for oncoming cars yourself. Tennessee Comprehensive Driver License Manual, p.63: “It means there is increased visibility ahead.”

A car is passing you on the left. Where should you keep your car?

In your lane, moving to the right. Drifting left as you are passed squeezes the passing car toward oncoming traffic. Tennessee Comprehensive Driver License Manual, p.63: “Staying in your lane, and moving to the right if being passed on the left.”

How much space must you leave between your car and a bicycle you are passing?

At least 3 feet. A gust of air from a car close by can knock a rider over. Three feet gives them room to wobble. Tennessee Comprehensive Driver License Manual, p.63: “When passing and overtaking a bicyclist proceeding in the same direction, do so slowly and leave at least a distance between you and the bicycle of not less than 3 feet.”

Why should you not stay alongside a truck you are passing?

You are in the driver's blind spot. Beside the cab, the truck driver cannot see you and may move over into your car. Tennessee Comprehensive Driver License Manual, p.64: “Complete your pass as quickly as possible.”

When may you back your car into a travel lane?

Only into a parallel parking space. Drivers coming toward a car's back end do not expect it to move at them and may not react in time. Tennessee Comprehensive Driver License Manual, p.64: “Never back a vehicle into any travel lane with the exception of backing into a parallel parking space.”

Parking beside a road outside city limits, how much road width must you leave for others?

At least 18 feet. A narrow gap forces passing cars toward the center line, into the path of oncoming traffic. Tennessee Comprehensive Driver License Manual, p.65: “No matter what, you must ensure that you leave at least 18 feet of road width for other traffic to pass your parked vehicle.”

Parking downhill next to a curb, which way should you turn your front wheels?

Toward the curb. If the car rolls, the tire bumps into the curb and stops instead of rolling into traffic. Tennessee Comprehensive Driver License Manual, p.65: “On a downhill with a curb: Turn the front wheels toward the curb (right) and set the parking brake.”

You may not park within how many feet of a fire hydrant?

15 feet. Firefighters need to reach the hydrant fast. A car in the way costs time during a fire. Tennessee Comprehensive Driver License Manual, p.65: “Within 15 feet of a fire hydrant”

What may you do at a white painted curb?

Stop just to pick up or drop off riders. White curbs keep the space open for quick drop-offs. A car left there blocks everyone else. Tennessee Comprehensive Driver License Manual, p.66: “Stop only long enough to pick up or drop off passengers.”

When you start to parallel park, how close may you be to the car beside you?

No closer than 2 feet. Pull up too close and you will clip the other car when you swing in. Tennessee Comprehensive Driver License Manual, p.66: “Your vehicle should not be any closer than two feet from the other vehicle.”

If your car breaks down on a highway, where should you park it if you can?

With all 4 wheels off the road. Any wheel left in the lane makes your car an obstacle for drivers coming fast. Tennessee Comprehensive Driver License Manual, p.66: “Park the vehicle with all four wheels off the traveled portion of the highway, if possible.”

Your parent's handicap placard is in your car, but your parent is not with you. May you park in a handicap space?

No, the holder must be riding along. Borrowing a family member's placard takes a space from someone who cannot walk far. Tennessee Comprehensive Driver License Manual, p.66: “Parking spaces marked with this symbol are only to be used by vehicles displaying a valid placard or license plate with this symbol, and only when transporting the person who was issued the placard or plate.”

As you pull into an angle parking space, what should you make sure of?

Your back end will clear the parked cars. Turn in too soon and your back fender scrapes the car beside the space. Tennessee Comprehensive Driver License Manual, p.67: “Make sure the rear of your car will clear the parked cars.”

Which of these will you not find on an interstate?

Traffic lights. Without lights and crossings, traffic does not stop. You have to match its speed to join it. Tennessee Comprehensive Driver License Manual, p.68: “There are no stop signs, no railroad crossings and no traffic lights.”

What is the acceleration lane on an interstate on-ramp for?

Speeding up to merge with traffic. Joining at a crawl forces fast cars to brake hard behind you. Matching speed lets you slip in. Tennessee Comprehensive Driver License Manual, p.68: “You must use the merging or acceleration lane to speed up and merge with fast-moving traffic already on the interstate.”

On a multi-lane interstate, which lane should you leave for faster traffic?

The far left lane. A slow car in the left lane makes faster drivers weave around on the right. Tennessee Comprehensive Driver License Manual, p.68: “On these roads, leave the extreme left lane for faster traffic.”

Traffic around you is going over the posted limit. What should you do?

Keep pace but stay at or under the limit. Other drivers speeding does not change the limit, and a ticket or crash still lands on you. Tennessee Comprehensive Driver License Manual, p.69: “Try to keep pace with traffic on the road, but don’t be lured into exceeding the posted speed to “stay with the flow of traffic.””

During which morning hours is a Tennessee HOV lane reserved?

7 to 9 a.m.. Outside those hours a solo driver may use the lane. Inside them it means a fine. Tennessee Comprehensive Driver License Manual, p.69: “During high inbound traffic hours (7–9 a.m.) and high outbound traffic (4–6 p.m.), the HOV lane is reserved for the exclusive use of:”

Exit signs are usually placed at least how far before the exit?

1 mile. That mile is your time to move over. Waiting for the exit itself leaves no room. Tennessee Comprehensive Driver License Manual, p.69: “Exit signs are usually placed at least one mile ahead of the exit turn-off.”

Approaching an interchange you do not know, what should you go by?

The signs for the turn you want. Interchanges come in many shapes. The signs, not a guess, put you on the right ramp. Tennessee Comprehensive Driver License Manual, p.70: “When approaching any type of interchange, follow the signs telling you how to make the turn you want to make.”

On the interstate, what must you do every time you change lanes?

Signal first. At interstate speed, a car that moves over with no signal gives the driver beside it no warning at all. Tennessee Comprehensive Driver License Manual, p.71: “Change lanes without signaling.”

What is interstate hypnosis?

Drowsiness from steady, dull driving. The hum lulls you into staring ahead half-asleep, and you stop noticing what traffic is doing. Tennessee Comprehensive Driver License Manual, p.71: “This is known as interstate hypnosis.”

What is rubbernecking?

Slowing down to look at a crash. Every driver who slows to stare forces the ones behind to brake, and the jam grows for miles. Tennessee Comprehensive Driver License Manual, p.72: “Slowing down to look at crashes or virtually anything else out of the ordinary is one of the worst congestion offenders.”

An emergency vehicle is stopped on the shoulder. What does Tennessee law require?

Yield the lane closest to it. Police, tow and road crews work inches from passing traffic. An open lane gives them a buffer. Tennessee Comprehensive Driver License Manual, p.72: “Tennessee law requires that motorists yield the lane closest to any emergency, maintenance or recovery vehicle that is stopped on the shoulder of the roadway.”

Your car starts having trouble on the interstate. Where should you go?

To the right shoulder. A car stopping in a travel lane gets hit from behind. The shoulder and flashers keep you out of the way and seen. Tennessee Comprehensive Driver License Manual, p.72: “If you have vehicle trouble, move to the right shoulder or emergency stopping area as soon as you can.”

After a minor interstate crash with no serious injuries, what may you do with a drivable car?

Move it to the emergency lane. A minor wreck left in a lane blocks traffic and invites a second, worse crash. Tennessee Comprehensive Driver License Manual, p.73: “If the vehicle is still drivable and there are NO SERIOUS PERSONAL INJURIES or deaths, you may pull the vehicle(s) to the emergency lane and await the arrival of a trooper or police officer to the crash scene.”

Your headlights must let you see a person on the highway at least how far ahead?

200 feet. Weak or dirty headlights show a walker in dark clothes too late to stop. The 200-foot rule sets the least you must be able to see. Tennessee Comprehensive Driver License Manual, p.74: “The law requires headlights that will enable you to see clearly any person on the highway at least two hundred (200) feet ahead of your car.”

What is glare recovery time?

The time your eyes need to readjust after glare. For a few moments after a bright car passes you cannot see what is in front of you. Slowing down buys back that lost time. Tennessee Comprehensive Driver License Manual, p.74: “This is called glare recovery time.”

Why should you turn off your headlights when you park at night, even briefly?

They still blind drivers coming toward you. A driver coming toward your parked car with its lights on may think you are moving in their lane and swerve. Tennessee Comprehensive Driver License Manual, p.75: “They are just as likely to blind approaching drivers when your car is stationary as they are when it is moving.”

How can wet pavement compare with icy pavement?

It can be just as treacherous. A wet road can let your car slide just like ice. At normal speed you may not stop or turn where you planned. Tennessee Comprehensive Driver License Manual, p.75: “Wet pavement can be as treacherous as icy pavement, so always reduce your speed in wet weather.”

What is the best advice for driving in fog or smoke?

Do not drive in it. In thick fog a stopped car can appear only a few feet away. No skill makes up for not being able to see. Tennessee Comprehensive Driver License Manual, p.75: “The best advice for driving in fog or smoke is "DON'T".”

On a cold, wet day, where can spots of ice hide?

In shade from trees or buildings. The road can look wet and safe in the sun, then turn to ice in the shadow of a building just ahead. Tennessee Comprehensive Driver License Manual, p.75: “On cold, wet days, shade from trees or buildings can hide spots of ice.”

What is hydroplaning?

Tires riding on water instead of the road. Once your tires float on water, a small turn of the wheel or a gust of wind can send the car into a spin. Tennessee Comprehensive Driver License Manual, p.76: “In heavy rain, your tires can lose all contact with the roadway due to water or "hydroplaning".”

What is the primary purpose of Rumble Stripes on Tennessee roads?

Better wet-night view of the edge line. On a wet night the edge line can vanish under a sheet of water. The grooves drain it so you can still see where the road ends. Tennessee Comprehensive Driver License Manual, p.76: “It has a secondary effect of the vibration and noise, however, its primary function is to improve wet-night visibility of the edge line.”

What causes skids?

Driving too fast for conditions. A speed that is fine on a dry road can be too fast on ice or rain. Slowing down is what keeps tires gripping. Tennessee Comprehensive Driver License Manual, p.76: “Skids are caused by drivers traveling too fast for conditions.”

If your wheels drop off the paved roadway, what should you do first?

Lift off the gas without braking hard. Hard braking with two wheels on dirt and two on pavement can spin the car. Coasting lets it slow down straight. Tennessee Comprehensive Driver License Manual, p.76: “Lift you foot off the gas pedal but do NOT suddenly apply the brake.”

Most cars can be swept away in how much moving water?

18 to 24 inches. Water that looks only knee deep can lift a car and push it off the road. A heavy car floats like a boat. Tennessee Comprehensive Driver License Manual, p.76: “In fact, most cars can be swept away in 18 to 24 inches of moving water.”

If you spot a tornado while driving, what should you do?

Get out and lie face down in a ditch. A tornado can toss a car and turn its glass into flying blades. Lying low in a ditch keeps you under the debris. Tennessee Comprehensive Driver License Manual, p.77: “Get out of the car, find shelter in a ditch or low-lying area and lie face down to protect yourself from flying debris.”

Before driving in winter, which windows must you clear of snow, ice or frost?

All of the windows. A small hole scraped in the windshield hides a child at the corner or a car in the next lane. Tennessee Comprehensive Driver License Manual, p.77: “Clear snow, ice or frost from ALL windows before driving.”

How soon after a drink does alcohol begin to be absorbed into the bloodstream?

Within 1 to 2 minutes. Alcohol reaches your blood almost at once. You cannot drink and rush home before it takes effect. Tennessee Comprehensive Driver License Manual, p.79: “Alcohol begins to be absorbed into the bloodstream within one to two minutes after an alcoholic beverage is consumed.”

What does Blood Alcohol Concentration (BAC) measure?

The percentage of alcohol in your blood. BAC is the number police and courts use. Knowing what it measures helps you see why every drink pushes it up. Tennessee Comprehensive Driver License Manual, p.79: “Blood Alcohol Concentration (BAC) is a measurement of the percentage of alcohol in the blood.”

At what BAC are you 7 times more likely to cause a crash than when sober?

.10 percent. A driver at .10 may still feel fine, but the chance of causing a crash has already jumped many times over. Tennessee Comprehensive Driver License Manual, p.79: “With a BAC of .10 percent, you are seven times more likely to cause a crash than if you were sober.”

Which two abilities most important to driving are affected by small amounts of alcohol?

Judgment and vision. Even a drink or two clouds what you see and how you decide, the two things driving leans on most. Tennessee Comprehensive Driver License Manual, p.80: “The two abilities most important to the driving task are judgment and vision, both of which are affected by small amounts of alcohol.”

How much does alcohol reduce your ability to see clearly at night?

By more than half. Night already hides walkers and dark cars. After drinking, you lose more than half of what little you could see. Tennessee Comprehensive Driver License Manual, p.80: “It reduces the ability to see clearly at night by more than half.”

What happens when alcohol is combined with tranquilizers or sedatives?

The effects are multiplied. A sleeping pill and one drink can hit you harder than either one twice over. The mix can put you to sleep at the wheel. Tennessee Comprehensive Driver License Manual, p.81: “For example, when alcohol is combined with another depressant, like tranquilizers or sedatives, the results are not just added together; they are multiplied.”

Besides public roads, where else does Tennessee's DUI law apply?

Shopping center parking lots. A parking lot is full of walkers and children. The DUI law follows you there, not just onto the highway. Tennessee Comprehensive Driver License Manual, p.81: “In Tennessee, it is unlawful for any person to drive or be in physical control of an automobile or other motor-driven vehicle on any public street, highway, road or alley, or while on the premises of any shopping center, trailer park, apartment house complex, or any place frequented by the public while:”

When do you give your consent to be tested for alcohol or drugs in Tennessee?

When you drive in Tennessee. You agree to the test when you choose to drive, not when you are pulled over. That is why saying no still costs you. Tennessee Comprehensive Driver License Manual, p.81: “By law, when you drive in Tennessee, you have given your consent to be tested to determine the alcohol or drug content of your blood.”

What is the minimum jail time for a first DUI conviction in Tennessee?

48 hours. Even one DUI means time behind bars, not just a ticket. The law treats it as a crime that could have killed someone. Tennessee Comprehensive Driver License Manual, p.82: “1st Conviction 48 hours (7 days if BAC is 0.20% or more)”

Your vehicle will be seized if you have two DUI convictions within how many years?

5 years. Losing the car takes away the tool of the crime. It stops a repeat drunk driver from simply driving off again. Tennessee Comprehensive Driver License Manual, p.82: “The driver’s vehicle will be seized if he/she has two DUI convictions within five years AND both events happened after January 1997.”

What may you be charged with if you drive impaired and cause a crash that kills someone?

Vehicular homicide. One choice to drive after drinking can end another person's life and send you to prison for it. Tennessee Comprehensive Driver License Manual, p.82: “If you are operating a motor vehicle under the influence of a drug or alcohol, and you are involved in a crash resulting in the death of another person(s), you may be charged with vehicular homicide.”

What does an ignition interlock device do?

Stops the car starting if BAC is too high. A car that will not start cannot be driven drunk. The device does the job a promise cannot. Tennessee Comprehensive Driver License Manual, p.82: “Only a motor vehicle equipped with a functioning ignition interlock device (which keeps a car from starting if the driver’s BAC is too high).”

For a driver aged 16 to 20, driving with what BAC leads to an underage driving while impaired conviction?

.02 percent. For a young driver there is almost no safe amount. One drink can put you over the line and cost you your license. Tennessee Comprehensive Driver License Manual, p.83: “A person who is at least 16, but is not yet 21 years old, and who is found: (1) driving with a BAC of .02 percent; (2) under the influence of alcohol; or (3) under the influence of any other intoxicant, will be convicted of underage driving while impaired.”

When should you decide that you will not drive after a night out?

Before you start drinking. After a drink or two your judgment is already slipping, so the choice is harder to make well. Make it while sober. Tennessee Comprehensive Driver License Manual, p.83: “If you are planning a night on the town, decide before you start drinking that you are not going to drive.”

Before issuing a license, what does Tennessee search through the Problem Driver Pointer System?

The National Driver Register. A driver who lost a license in another state cannot just move here and start over. The search finds the problem. Tennessee Comprehensive Driver License Manual, p.85: “The Problem Driver Pointer System (PDPS) is used by the Tennessee Department of Safety and Homeland Security to search the National Driver Register before issuance of a driver license.”

Two reckless driving violations within how long can cost you your license?

12 months. One reckless driving charge is a warning. Two in a year shows a pattern that puts everyone near you at risk. Tennessee Comprehensive Driver License Manual, p.85: “Two reckless driving violations within 12 months.”

When your license is suspended or revoked, within how many days must you turn it in?

20 days. A suspended license still in your wallet tempts you to drive, and it can fool an officer. Turning it in ends that. Tennessee Comprehensive Driver License Manual, p.85: “Whenever a driver license is suspended or revoked, it must be turned in to the Department of Safety within 20 days of the suspension or revocation.”

Within how many days must you report a new address to the Department of Safety?

10 days. Suspension notices go to the address on file. With an old address you may be driving suspended and not know it. Tennessee Comprehensive Driver License Manual, p.86: “IMPORTANT: If you have a new address, you must report it to the Department of Safety within ten (10) days of the change.”

How does the Department of Safety track traffic violations and crashes on your record?

Each is given a point value. Points add up over time. Several small tickets can cost your license as surely as one big one. Tennessee Comprehensive Driver License Manual, p.86: “Each traffic violation or crash on a driver’s record is given a point value.”

What does a restricted driver license allow?

Driving for specific listed purposes. A restricted license is not a free pass. Driving anywhere outside the listed purposes is driving without a license. Tennessee Comprehensive Driver License Manual, p.86: “The restricted license permits the driver to operate a motor vehicle for very specific purposes that are spelled out when the license is issued.”

Within how many days must you send a medical report after the department asks about a disorder that affects your driving?

30 days. Some illnesses can make a driver black out without warning. The report lets a doctor say whether it is safe. Tennessee Comprehensive Driver License Manual, p.88: “When information is received that an individual’s ability to drive is affected by a physical or mental disorder, the driver will be required to submit (within thirty (30) days of notification) a medical report from a medical doctor.”

What does liability insurance cover?

Damages you cause to others. If you hit another car, liability coverage pays for their damage so the bill does not land on you alone. Tennessee Comprehensive Driver License Manual, p.88: “Liability insurance provides coverage for damages you cause to other persons.”

You must immediately notify police of a crash involving property damage over what amount?

$50 in damage. Even a small crash can hide an injury or a dispute about who paid. A police report sets down the facts. Tennessee Comprehensive Driver License Manual, p.89: “Drivers must immediately notify the local police department if the crash occurs within a municipality, otherwise to the County Sheriff’s office or the nearest Tennessee Highway Patrol, of any crash involving death, injury or property damage over fifty dollars ($50).”

If you are involved in a crash, where must you stop?

At or as close to the scene as possible. Leaving a crash scene can turn a fender bender into a hit-and-run charge, and someone hurt may be left without help. Tennessee Comprehensive Driver License Manual, p.89: “The law requires drivers of vehicles involved in a crash to stop immediately at the scene, or as close to the scene as possible without obstructing traffic.”

How far ahead do defensive drivers try to focus their eyes?

10 to 15 seconds ahead. If you only watch the bumper in front of you, a stalled car or a sudden stop up the road reaches you with no time left to react. Tennessee Comprehensive Driver License Manual, p.93: “Defensive drivers try to focus their eyes 10 to 15 seconds (about the distance of 1 city block) ahead.”

How big a gap in traffic do you need, at a minimum, to change lanes or merge?

4 seconds. Squeezing into a short gap makes the car behind brake hard for you. A wider gap lets you merge without forcing anyone to react. Tennessee Comprehensive Driver License Manual, p.94: “A minimum four-second gap is needed whenever you change lanes, enter a roadway or when your lane merges with another traffic lane.”

An angry driver is following you. Where should you go?

To a police station or public place. Driving home shows a hostile driver where you live. A police station or busy public place puts help between you and them. Tennessee Comprehensive Driver License Manual, p.95: “If a driver follows you, go to a police station or a public place where you can get help.”

What are the three options drivers have for avoiding a collision?

Stop, turn, or speed up. Many drivers freeze when a crash looks likely. Knowing the 3 moves ahead of time helps you pick one fast instead of doing nothing. Tennessee Comprehensive Driver License Manual, p.96: “In avoiding a collision, drivers have three options: 1. Stop 2. Turn 3. Speed Up”

When should you be most alert for deer on the road?

Around dusk and dawn. Deer move most in dim light, just when they are hardest to see. Knowing the time helps you slow down and scan the roadside. Tennessee Comprehensive Driver License Manual, p.97: “Be particularly alert at dusk and dawn, when these animals venture out to feed.”

How often should drivers have their eyes checked by an eye specialist?

Every 1 to 2 years. Eyesight can fade so slowly that you do not notice. A regular exam catches it before you miss a sign or a child in the road. Tennessee Comprehensive Driver License Manual, p.99: “you should have your eyes checked every year or two by an eye specialist.”

What is the least tread depth a tire can have before it is illegal and must be replaced?

2/32 of an inch. Worn tires cannot push water out of the way. On a wet road they slide instead of stopping, and the car can hydroplane. Tennessee Comprehensive Driver License Manual, p.100: “If the tread does not come at least to Lincoln’s head (2/32 inch), the tire is illegal and unsafe and you need it replaced.”

In which weather do car batteries run down more quickly?

Cold or damp weather. A battery that is weak in the fall may not start the car on the first cold morning, leaving you stuck. Tennessee Comprehensive Driver License Manual, p.100: “Car batteries tend to run down more rapidly in cold or damp weather.”

When do collisions involving several vehicles often happen?

When drivers' speeds differ from traffic. Cars moving the same way at the same speed cannot hit each other. A car much faster or slower than the rest keeps closing gaps. Tennessee Comprehensive Driver License Manual, p.101: “Collisions involving multiple vehicles often happen when drivers go faster or slower than other traffic.”

Is there a crosswalk at an intersection with no painted crosswalk lines?

Yes, every intersection has a crosswalk. A walker at a corner with no lines still has a crosswalk. Driving on because the paint is missing can hit a person you must yield to. Tennessee Comprehensive Driver License Manual, p.103: “There is a crosswalk at every intersection, even if painted lines and boundaries do not mark the crossing.”

Where must pedestrians walk when a sidewalk is available?

On the sidewalk. A person walking in the road shares the lane with cars. Drivers do not expect them there and may not see them in time. Tennessee Comprehensive Driver License Manual, p.104: “It is unlawful for pedestrians to walk in the road where there are sidewalks.”

What are the most common causes of car-bicycle collisions?

Drivers turning across a bicycle's path. Drivers watch for cars and misjudge how fast a bike is coming. Knowing the two classic turns tells you when to look twice. Tennessee Comprehensive Driver License Manual, p.105: “The most common causes of collisions are drivers turning left in front of an oncoming bicycle or turning right, across the path of the bicycle.”

From how far ahead must a bicycle's front lamp be visible at night under Tennessee law?

500 feet. A rider without a light is nearly invisible to a driver at night. The lamp gives you time to see the bike and slow down. Tennessee Comprehensive Driver License Manual, p.106: “Tennessee law requires that a bicycle used at night must be equipped with a lamp on the front that emits a white light visible from a distance of at least 500 feet to the front and either a red reflector or lamp emitting a red light that is visible from distance of 500 feet to the rear when directly in front of lawful upper beams of head lamps on a motor vehicle.”

Who causes about two-thirds of car-motorcycle collisions?

The car driver turning in front of it. Drivers look for cars and miss a narrow motorcycle. A left turn across its path is how most of these crashes start. Tennessee Comprehensive Driver License Manual, p.107: “Research shows that two-thirds of car-motorcycle collisions are caused, not by the motorcyclist, but by the driver who turned in front of the motorcycle.”

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

Up to 200 feet. A car close behind a truck vanishes from its mirrors. If the truck slows or backs up, its driver does not know you are there. Tennessee Comprehensive Driver License Manual, p.109: “A truck’s blind spots are immediate in front, on either side of the car and up to 200 feet in the rear.”

You have just passed a truck and its driver blinks the headlights. What does it mean?

You are clear to pull back in front. The truck driver can see the gap better than you can. The flash tells you there is room, but still check for its front in your mirror. Tennessee Comprehensive Driver License Manual, p.109: “If the truck or bus driver blink their vehicle headlights after you pass, it’s a signal that you are cleared to pull back in front of their vehicle.”

Near a commercial vehicle weigh station, which lane should you avoid?

The right lane. Trucks leaving a weigh station start slowly and need the right lane to get up to speed. A car there blocks their way back in. Tennessee Comprehensive Driver License Manual, p.109: “When you are near a Commercial Vehicle Weigh Station, avoid driving in the right lane so slow-moving trucks can easily merge back onto the roadway.”

How far away from a school bus should children stay?

10 feet. A bus driver cannot see a small child right next to or behind the bus. Ten feet of space puts the child where the driver can see. Tennessee Comprehensive Driver License Manual, p.111: “Children should stay ten feet away from the school bus and NEVER go behind the bus.”

In most cases, how fast does farm machinery travel on the road?

Less than 25 mph. Coming over a hill at 55 mph, you close on a tractor going 25 mph very fast. Expect it so you can slow in time. Tennessee Comprehensive Driver License Manual, p.111: “In most cases, these vehicles will be traveling at less than 25 M.P.H.”

A work zone has no reduced speed limit posted. What limit applies?

The normal posted limit. No lower sign does not mean no limit. The normal limit still applies, and workers may be only a few feet away. Tennessee Comprehensive Driver License Manual, p.112: “The reduced speed limits are clearly posted within the work zone and if there are no reduced speed limit postings, drivers should obey the normal posted speed limit.”

About how far does a train traveling at 55 mph need to stop?

About a full mile. By the time a train crew sees your car on the tracks, it is far too late to stop. Only you can avoid the crash. Tennessee Comprehensive Driver License Manual, p.113: “A train traveling at 55 miles per hour takes a full mile to stop.”

Who must wear a safety belt in a 15-passenger van in Tennessee?

Every person in the van. These vans roll over more easily than cars. An unbelted rider is thrown around or out of the van in a rollover. Tennessee Comprehensive Driver License Manual, p.114: “All occupants in 15-passenger vans must wear safety belts at all times.”

How should weight be loaded in an RV for the best handling?

Low and even on both sides. Heavy items stored high or on one side make an RV sway and lean in turns. Loose ones can slide and change how it brakes.
