1. A large X with the letters R and R beside it is painted across your lane. What does it mean?
Show answer
Answer A: A railroad crossing lies a short distance ahead
The pavement marking repeats the advance warning for a grade crossing, and it is used on paved approaches where speeds are high or where gates are installed.
-
2. A teen applying for a Tennessee learner permit currently holds a suspended license from another state. What does this do to the Tennessee application?
Show answer
Answer B: It makes the teen ineligible for the graduated program until that status is resolved
Tennessee treats a suspension or revocation in any state, along with habitual offender status, as a disqualifying factor for the graduated licensing program.
-
3. Your vehicle has a blind spot warning light in the door mirror. What should that mean for your habits?
Show answer
Answer B: You still check the blind spot yourself, because the system can miss a rider
Blind spot systems are an aid, not a substitute, and a motorcycle or a bicycle can be missed or arrive faster than the sensor expects.
-
4. Your headlights suddenly go out while you are driving at night. What should you do?
Show answer
Answer A: Try the dimmer switch and the headlight switch, turn on the hazard lights and pull off the road
Switching between high and low beams or cycling the light switch sometimes restores the lights. If not, use the hazard and parking lights to get off the road safely.
-
5. Why do young drivers carrying several friends face a higher crash risk?
Show answer
Answer D: Because young passengers are a strong source of distraction and pressure
Crash risk for new drivers rises with each extra young passenger, mainly through distraction and social pressure.
-
6. You approach an intersection where the signal is flashing yellow. What should you do?
Show answer
Answer D: Slow down and cross the intersection with caution
A flashing yellow signal warns you to slow down and cross with care; it does not require a stop, but it does not give you priority either.
-
7. A curb sign reads No Standing. What does it allow you to do?
Show answer
Answer B: Stop only long enough to pick up or drop off passengers
No Standing bars waiting for any purpose except the brief moment needed to let passengers in or out, which is stricter than No Parking.
-
8. The blue signs mounted before a freeway interchange that carry the logos of individual businesses are
Show answer
Answer C: specific service signs, which show the brands available at that exit
Specific service signs, often called logo signs, list eligible businesses for categories such as gas, food, lodging, camping, attractions and 24-hour pharmacies at the upcoming interchange.
-
9. A strong wind is blowing across an open stretch of road. Besides the gusts, what else should you watch for?
Show answer
Answer A: Branches, dust and loose objects blown into your path
High wind strips branches, litter and dust onto the roadway and can push other vehicles out of their lane, so scan much further ahead than usual.
-
10. You are stopped at a T-intersection and a driver on the through road is signaling a right turn into your road. What is the safe assumption?
Show answer
Answer B: The driver may not actually turn, so wait until the vehicle slows and starts turning
A blinking signal may have been left on by mistake or may be for the next street, so wait until the vehicle actually slows and turns.
-
11. A sign warns that the right lane ends ahead, and traffic is still flowing freely. What should you do if you are in that lane?
Show answer
Answer C: Signal, adjust your speed and move left in good time before the lane ends
When traffic is moving freely there is room to merge early and smoothly, which avoids the last-second lane change at the closure point.
-
12. Snow has covered the pavement markings on a two-lane road. How should a driver judge lane position?
Show answer
Answer B: By the tracks of other traffic and the roadside features
With the markings hidden, ruts left by earlier traffic, signs, poles and the line of the shoulder are the best clues to where the lane runs.
-
13. Why is it dangerous to make a left turn from the second lane from the center?
Show answer
Answer C: Because a driver in the lane beside you is turning into the same space
Drivers in the proper turn lane are entitled to that space, and turning across them puts two vehicles into one path through the intersection.
-
14. You see an open curb space on the opposite side of a two-way street. What should you do?
Show answer
Answer B: Drive on, turn around, and come back on that side
You must park on the right, facing the direction of travel, so reaching a space on the other side means going around rather than crossing into it.
-
15. Where is a U-turn generally the most reasonable choice?
Show answer
Answer B: At an intersection where it is permitted and you can see well both ways
A U-turn needs a legal place and a long clear view in both directions, which is why a permitted intersection with open sight lines is the usual choice.
-
16. You are backing a trailer and want its rear to move to the left. Which way should you turn the steering wheel?
Show answer
Answer A: Move the bottom of the wheel to the left, which turns the top to the right
A trailer moves opposite to the tow vehicle's steering when backing. Holding the wheel at the bottom and moving your hand in the direction you want the trailer to go makes this easier.
-
17. You are backing straight down a driveway while looking over your right shoulder. Where should your left hand be?
Show answer
Answer C: At the top of the steering wheel, holding it with a firm grip
With one hand at the top of the wheel you can hold a straight course and make small corrections while your body is turned to look behind.
-
18. You want to pass on a two-lane road where several people are walking on the narrow shoulder ahead. What should you consider?
Show answer
Answer D: There is no escape room if the pass goes wrong, so wait for a better place
A pass depends on having somewhere to go if it goes wrong, and a shoulder occupied by pedestrians removes that option for both vehicles.
-
19. At night you are waiting to turn left and can see only the headlights of an approaching vehicle. Why should you allow a bigger margin?
Show answer
Answer D: Because lights alone make speed and distance hard to judge
With no other visual cues, two points of light give you very little information about how fast the vehicle is closing, so leave extra margin.
-
20. Why is heavy braking a poor idea while two wheels are still on a soft shoulder?
Show answer
Answer B: The two sides have different grip, so the vehicle can pull sharply
With one pair of wheels on pavement and the other on loose material, hard braking slows one side more than the other and swings the vehicle around.
-
21. How does marijuana affect a driver?
Show answer
Answer C: It slows reaction time and impairs judgment of time and distance
Marijuana impairs coordination, attention and the ability to judge speed and distance. Driving while impaired by it is illegal everywhere, even where its use is legal.
-
22. How should your speed behave while you move from one lane into the next?
Show answer
Answer C: Keep it steady or adjust it smoothly to match the traffic in the new lane
A lane change works best as a smooth movement at the speed of the lane you are joining, since sudden braking or acceleration surprises the drivers around you.
-
23. What is the most common cause of rear-end collisions?
Show answer
Answer C: Following too closely to stop in time
A driver who leaves too little space has no room to perceive, react and brake when the vehicle ahead slows, which is why space management prevents rear-end crashes.
-
24. Two vehicles meet on a steep, narrow mountain road with no room to pass. Which driver should back up?
Show answer
Answer C: The driver heading downhill, who has more control while reversing
On a narrow mountain road the vehicle facing downhill yields, because backing uphill gives better control than reversing down a grade.
-
25. In heavy fog at night on a rural two-lane road, which marking best helps a driver hold position?
Show answer
Answer C: The solid white line along the right edge
Steering by the right edge line keeps a driver clear of oncoming traffic, while watching the center line tends to pull the vehicle toward it.
-
26. Why is parking against the flow of traffic dangerous even when nobody complains?
Show answer
Answer D: Because you had to cross traffic to get there and must cross again to leave
Parking on the wrong side means driving against traffic at both ends of the stop, and your reflectors and lights face the wrong way while you are there.
-
27. Why should heavy objects in the passenger compartment be secured?
Show answer
Answer A: Because loose objects fly forward in a crash and can injure the people
Anything loose keeps traveling at the speed of the vehicle when the vehicle stops, so it strikes the occupants with great force.
-
28. Why does a long downhill grade lengthen the distance you need to stop?
Show answer
Answer C: Because gravity keeps pulling the vehicle forward as you brake
On a downgrade gravity works with the vehicle and against the brakes, so the same speed needs noticeably more distance than it would on level ground.
-
29. When should you enter a destination into a navigation device?
Show answer
Answer B: Before you start driving, or after parking in a safe place
Programming a route is a visual, manual and mental task at the same time, so it belongs to the moments before the vehicle moves rather than to any point in traffic.
-
30. You are following a tractor-trailer so closely that its rear doors fill your windshield. What is the main problem?
Show answer
Answer D: You cannot see the road ahead and the truck driver cannot see you
A truck has a deep blind spot directly behind it, and tailgating also hides everything in front of the truck from you. Drop back so you can see and be seen.
