1. Fresh snow covers the road and earlier vehicles have left clear tracks. What line is usually best?
Show answer
Answer B: The existing tracks, where more of the tire can reach the surface
Running in the cleared tracks puts more rubber on the road surface than ploughing through loose snow, provided the tracks have not turned to polished ice.
-
2. You are waiting to turn left across two oncoming lanes when a driver in the near lane stops and waves you through. What should you do?
Show answer
Answer D: Turn only after checking the far lane yourself
The waving driver cannot give away the right of way of the traffic in the second lane, which may not be stopping at all.
-
3. The left-turn signal facing you shows a flashing yellow arrow. What does it mean?
Show answer
Answer C: You may turn left after yielding to oncoming traffic and to pedestrians
A flashing yellow arrow permits a left turn but gives no protection, so you must yield to oncoming vehicles and to people in the crosswalk.
-
4. You arrive at an intersection where the traffic signal is completely dark because of a power failure. How should you proceed?
Show answer
Answer C: Treat the intersection as an all-way stop
When a signal shows no indication at all, drivers on every approach must stop and then take turns, exactly as at an all-way stop.
-
5. A Tennessee driver receives a points suspension notice and never requests a hearing. How long is the suspension?
Show answer
Answer D: Six to twelve months
Failing to request the administrative hearing leads to a suspension of six to twelve months, and reinstatement requires proof of insurance and payment of fees.
-
6. How many points does Tennessee assess for failing to stop at a railroad crossing when required?
Show answer
Answer D: 8 points
Failing to stop at a railroad crossing sits at the top of the schedule with 8 points, the same weight as the most serious violations listed.
-
7. You are stopped at a stop sign waiting to turn onto a highway where traffic moves at 55 mph. How should you choose your gap?
Show answer
Answer A: Wait for a much larger gap than the one you would accept on a city street
Fast traffic covers ground while you are still accelerating, so the gap that feels adequate at 25 mph is dangerously short at highway speed.
-
8. What happens when tires are driven underinflated for a long time?
Show answer
Answer D: They wear at the edges, they run hot and they are more likely to fail
An underinflated tire flexes too much, which wears the shoulders and builds up heat that can destroy the tire.
-
9. A sign reads MINIMUM SPEED 40. What does it require of a driver?
Show answer
Answer C: Not to drive below that speed when conditions allow
A minimum speed limit keeps unnecessarily slow vehicles from obstructing traffic, but it never overrides the duty to slow down for weather or congestion.
-
10. You are turning left at an intersection just beyond the crest of a hill. What is the added risk?
Show answer
Answer B: Oncoming vehicles appear with very little warning and close quickly
A crest hides approaching traffic until it is close, so the gap you thought was empty can fill in the time the turn takes.
-
11. The trapezoid sign shape is associated with
Show answer
Answer C: recreational and cultural interest area signing
The trapezoid is used for recreational and cultural interest area guide signs and for national forest route markers.
-
12. How must a Tennessee child who is four through eight years old and shorter than four feet nine inches be transported?
Show answer
Answer C: In a belt positioning booster seat in the back seat
Tennessee requires a belt positioning booster seat for children four through eight who are under four feet nine inches, and the booster must be used in the back seat when the vehicle has one.
-
13. Another vehicle is passing you on a two-lane road. What should you do with your speed?
Show answer
Answer A: Hold your speed or ease off slightly to shorten the pass
Speeding up strands the passing driver in the oncoming lane, while a steady speed or a slight lift lets the pass finish quickly and safely.
-
14. When is a child ready to use a vehicle seat belt without a booster seat?
Show answer
Answer A: When the lap belt lies across the upper thighs and the shoulder belt crosses the chest
Belt fit, not age, decides readiness. Until the child is tall enough for the lap belt to sit on the thighs and the shoulder belt on the chest, a booster is needed.
-
15. In Tennessee, what blood alcohol concentration makes a driver aged 21 or older legally intoxicated?
Show answer
Answer C: 0.08 percent
Tennessee, like the rest of the country, sets legal intoxication for adult drivers at a blood alcohol concentration of 0.08 percent.
-
16. You notice a bulge on the sidewall of one of your tires. What should you do?
Show answer
Answer D: Have the tire replaced before driving far, because it could blow out
A sidewall bulge means the internal cords have broken and only the rubber is holding the air. The tire can fail suddenly at any speed.
-
17. The road ahead is broken up with potholes and rough patches. What should you do?
Show answer
Answer C: Slow down, since a hole hit at speed can wreck a tire or wheel
A lower speed cuts the impact on tires, wheels and suspension and gives you time to choose a line through the rough surface.
-
18. On a wet road, how should a driver adjust after passing this sign?
Show answer
Answer B: Start braking earlier, because a slippery surface lengthens the stopping distance
A wet surface lengthens stopping distance, so the extra warning distance should be spent braking gently and early instead of late and hard.
-
19. On a multi-lane street, a yield line is painted well back from an unsignalized crosswalk rather than right at it. Why?
Show answer
Answer D: So drivers in the other lanes can see the pedestrian
Setting the yield line back keeps a stopped vehicle from hiding a crossing pedestrian from drivers in the next lane, which is a common cause of these crashes.
-
20. You are stopped at a stop sign on a two-way stop intersection and the cross street has no stop signs at all. What does that mean for you?
Show answer
Answer A: You yield to all cross traffic no matter how long that takes
At a two-way stop only your direction is controlled, so there is no taking turns; you wait for a gap big enough to enter safely.
-
21. On a rural two-lane road you pass small blue signs, each naming one business with an arrow and a distance. What are they?
Show answer
Answer D: Tourist-oriented directional signs for traveler businesses
Tourist-oriented directional signs carry a white legend on blue and are used on rural conventional roads to guide travelers to eligible businesses.
-
22. A sign reads REDUCED SPEED LIMIT AHEAD. What does it tell you?
Show answer
Answer D: A lower limit begins further along the road
The sign gives advance notice so a driver can slow gradually, and the new figure takes effect at the speed limit sign that follows.
-
23. How may a two-way left-turn lane never be used?
Show answer
Answer B: As a through travel lane or a passing lane
The lane exists only for turning movements, so traveling or passing along it puts you head-on with vehicles turning from the opposite direction.
-
24. Where do you find how much weight your vehicle may carry?
Show answer
Answer C: On the placard in the driver door opening
The certification placard in the driver door opening gives the load limit and the recommended cold tire pressures for the vehicle as built.
-
25. Loose gravel has been swept into the middle of your lane on a downhill bend. Which controls are affected most?
Show answer
Answer D: Steering and braking, since the loose stones roll under the tires
Gravel rolls between rubber and pavement, so the tires can neither turn the vehicle nor slow it as they would on a clean surface.
-
26. What injury does a correctly set head restraint help prevent?
Show answer
Answer A: A neck injury of the kind caused when your vehicle is struck from behind
In a rear impact the body is pushed forward and the head restraint stops the head from whipping backward.
-
27. You are about to pass another vehicle at night with your high beams on. What should you do?
Show answer
Answer C: Switch to low beams as you come up behind it and while you are alongside
High beams shining into the mirrors of the vehicle ahead blind the very driver whose reaction you depend on during the pass.
-
28. A small yellow plaque showing a speed number below a curve warning sign gives
Show answer
Answer C: the speed recommended for the condition being warned about
The advisory speed plaque belongs to the warning series and states the speed judged safe for the condition ahead under good circumstances, not a regulatory limit.
-
29. Which family of signs normally uses a rectangle that is wider than it is tall?
Show answer
Answer B: Guide signs, which name routes and destinations
Guide signs are laid out as horizontal rectangles because they have to carry route numbers, place names and distances side by side.
-
30. A line beside your lane is painted about twice the normal width. What does the extra width convey?
Show answer
Answer B: Greater emphasis on the restriction it carries
Width is part of the marking code: a wide line carries more emphasis than a normal one, which is why it is used at gores and channelizing lines.
