1. Where should a rear-facing infant seat never be placed?
Show answer
Answer C: In a front seat with an active passenger air bag
A deploying front air bag strikes the back of a rear-facing seat with enormous force. Rear-facing seats belong in the back seat.
-
2. Besides a chemical test, what else supports an impaired driving charge?
Show answer
Answer B: The officer's observations of the driving and the driver
Weaving, slow responses, speech and balance observed by the officer are evidence in their own right, which is why a driver can be charged on behavior alone.
-
3. You are traveling beside a solid white lane line. What does it tell you?
Show answer
Answer B: Crossing it is discouraged or prohibited, so stay in your lane
A solid white line separates lanes going the same direction where lane changing is discouraged or prohibited, such as where a through lane meets a mandatory turn lane.
-
4. You have just had bad news and you feel very upset. What should you do?
Show answer
Answer B: Wait until you have calmed down, or else let somebody else drive
Strong emotion takes attention away from the road as surely as alcohol or fatigue, so it is a reason not to drive yet.
-
5. On a two-way street, where and how should you park at the curb?
Show answer
Answer C: On the right side, facing the way traffic moves
On a two-way street you must park on the right, headed in the direction of travel; parking facing traffic is prohibited.
-
6. A yellow diamond showing a truck is posted beside a quarry entrance. What is it warning about?
Show answer
Answer A: Trucks turning onto the highway from that entrance
A truck crossing or trucks entering sign is used where heavy vehicles pull onto the road from a site, and they accelerate slowly once they are on it.
-
7. You are about to make a three-point turn on a narrow two-way street. What is the first step?
Show answer
Answer B: Pull close to the right edge, signal left and check traffic both ways
A three-point turn starts from a stop at the right edge with a left signal, and you only move once you have checked that both directions are clear.
-
8. Someone stops drinking heavily at two in the morning and drives to work at eight. What is true?
Show answer
Answer A: They may still be impaired and over the limit
The body removes alcohol at a slow, fixed rate, so a heavy night can leave a driver impaired well into the next morning no matter how they feel.
-
9. Your passengers are being noisy and you are losing concentration. What should you do?
Show answer
Answer B: Ask them to settle down, or pull over safely until they do
The driver is responsible for the conditions inside the vehicle, and stopping is always better than driving distracted.
-
10. The crossing gates begin to lower while your vehicle is still on the railroad tracks. What should you do?
Show answer
Answer B: Keep going forward and push through the gate if it should block your way
Gates are made to break away, and driving forward off the tracks is far safer than staying between them or backing up.
-
11. You approach a one-lane bridge and there is a yield sign facing your side of it. What does that mean?
Show answer
Answer B: Oncoming traffic crosses the bridge first and you wait at the approach
At a one-lane bridge the yield sign tells one direction to give way, so you wait clear of the bridge until oncoming traffic has crossed.
-
12. You have stopped after a crash. Why should the engines of the vehicles involved be switched off?
Show answer
Answer A: To reduce the risk of a fire starting around any fuel that has spilled
Crashes often break fuel lines, and a running engine is a source of ignition, so switching off lowers the risk of fire.
-
13. You receive a phone call that you feel you must answer while driving. What is the safest way to take it?
Show answer
Answer D: Pull off the road, stop in a safe place and then answer
No call is worth a crash. Stopping in a safe location removes the distraction completely, while every other option divides your attention.
-
14. How many points does Tennessee assess for failing to yield the right-of-way?
Show answer
Answer D: 4 points
Failing to yield the right-of-way is another 4 point violation on the Tennessee schedule.
-
15. There is a driveway and a side street between you and the corner where you will turn right. When should you signal?
Show answer
Answer C: After passing the openings, so nobody pulls out in front of you
A signal switched on before an opening tells drivers waiting there that you are turning in, and they may pull out into your path.
-
16. Under what combination of circumstances might a Tennessee driver qualify for a waiver of the ignition interlock requirement after a DUI conviction?
Show answer
Answer A: The conviction involved a BAC under 0.08, non-alcohol impairment, or a refusal, and there was no accident, no minor passenger and no prior DUI within 10 years
The waiver requires both a qualifying type of conviction and a clean surrounding record, including no accident, no minor passenger and no other DUI in the prior decade.
-
17. Why would this sign be installed on an approach?
Show answer
Answer B: Because the signal cannot be seen from far enough back for a driver to react in time
Advance notice of a signal is used where a crest, a curve, trees or a building keep the signal heads out of view until a driver is already too close to stop comfortably.
-
18. How should your following distance change in heavy rain?
Show answer
Answer D: It should be increased well beyond what you use on dry pavement
Wet pavement lengthens stopping distance and rain cuts visibility at the same time, so a larger gap gives you the extra seconds needed to see a problem and stop for it.
-
19. The traffic around you is moving well above the limit on a wide highway. What should you do?
Show answer
Answer D: Keep to the limit and stay to the right, letting faster traffic pass
The limit is a legal maximum, and the safe way to differ from the traffic around you is to keep right and let it go by.
-
20. A Tennessee driver whose license is still revoked for DUI is caught driving without the required ignition interlock. What is the immediate consequence?
Show answer
Answer B: Arrest for driving on a revoked license, with the vehicle subject to seizure
Driving without the required interlock while still revoked exposes the driver to arrest for driving on a revoked license and possible vehicle seizure.
-
21. A flashing red arrow is displayed for your turning lane. What does it require?
Show answer
Answer D: Stopping, then turning when the way is clear
A flashing red arrow is treated like a stop sign for that movement: come to a full stop, then turn when it is safe and no one has to be cut off.
-
22. A ball rolls into the street from between parked cars ahead of you. What should you expect and do?
Show answer
Answer A: Expect a child to follow it and be ready to stop
A ball is usually followed by a child who is watching the ball and not the traffic. Slow down and be prepared to stop immediately.
-
23. You are stopped in a shared through and right-turn lane with your right signal on, and a bicyclist rides up along your right side. What should you do?
Show answer
Answer A: Let the bicyclist clear the intersection or move ahead before you turn
A cyclist alongside your right side is in the path your turn will sweep across, so wait until that space is clear before turning.
-
24. A high truck ahead of you hides the traffic signal as you approach the intersection. What should you do?
Show answer
Answer A: Drop back so you can see the signal and the truck's brake lights
Extra following distance restores your view of the signal, so you are reacting to the light yourself rather than copying the truck driver.
-
25. What makes up the total distance needed to bring a vehicle to a stop?
Show answer
Answer A: The distance covered while you perceive the hazard, the distance covered while you react, and the braking distance
Total stopping distance combines the ground covered while you notice the hazard, the ground covered while you move your foot to the brake, and the ground covered while the brakes slow the vehicle.
-
26. You are turning left into a street that is divided by a raised median. Which side should you enter?
Show answer
Answer C: The right-hand roadway, so that you travel on the proper side
A raised median separates two directions of travel, so the turn must be completed into the roadway carrying traffic your way.
-
27. At many crossings the walk indication appears only after a button is pressed. What happens if a pedestrian does not press it?
Show answer
Answer B: The signal may cycle without showing a walk indication
An actuated pedestrian phase is called in by the pushbutton, so without it the controller may serve the vehicle movements alone.
-
28. How long must a Tennessee Level I learner permit be held before the holder can move up to an Intermediate Restricted License?
Show answer
Answer C: At least 180 days
Tennessee requires the learner permit to be held for a minimum of 180 days before the teen can advance to the next stage.
-
29. How long should a glance at a mirror or an instrument take?
Show answer
Answer A: A brief glance of about a second, returning your eyes to the road at once
Checks should be quick flicks of the eyes. At highway speed, a few seconds with your eyes off the road covers a distance long enough for a hazard to appear.
-
30. A sign showing a figure with an outstretched thumb inside a red circle with a slash means that
Show answer
Answer B: soliciting a ride is prohibited there
The no hitchhiking sign bars standing beside the road to solicit a ride, and it is common along freeway ramps and shoulders.
