1. Once a driver has joined the route this sign begins, how is the rest of the way marked?
Show answer
Answer B: By further markers of the same kind at each turn, until the original road is rejoined
The alternate route is signed continuously, with a marker at every turn, so a driver with no local knowledge can follow it back to the original road.
-
2. 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.
-
3. As speed rises, which part of the total stopping distance grows the fastest?
Show answer
Answer B: The braking distance, which grows far faster than speed itself
Perception and reaction distances grow in step with speed, but braking distance grows roughly with the square of speed, so it dominates at higher speeds.
-
4. A driver stopped at a red signal wants to turn right and this sign is posted at the corner. What is permitted?
Show answer
Answer A: Nothing: the turn is barred whether the signal is red or green
The restriction works independently of the signal, so the usual permission to turn right after stopping at a red light does not exist where this sign is posted.
-
5. 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.
-
6. You are approaching the entry of a roundabout and a pedestrian is crossing the marked crosswalk on your approach lane. What must you do?
Show answer
Answer D: Stop before the crosswalk and let the pedestrian cross
Roundabout crosswalks sit a short distance back from the yield line, and drivers must yield there before they ever reach the circulating lanes.
-
7. A pedestrian is crossing a wide four-lane street and has reached the lanes on the far side. When may you go on?
Show answer
Answer C: Only after the person has finished crossing the roadway
Waiting until the pedestrian has finished crossing is correct in every state and removes any doubt about how much clearance your state demands.
-
8. You are at a red light where right turns on red are allowed, you cannot see clearly, and the driver behind sounds the horn. What should you do?
Show answer
Answer C: Stay stopped until you can see that the turn is safe
Turning right on red is permitted, never required, so you wait until you can see that the way is clear no matter what the driver behind does.
-
9. You see smoke coming from under the hood while driving. What should you do?
Show answer
Answer D: Signal, pull well off the road, shut off the engine and move everyone away from the vehicle
Stopping and shutting off the engine cuts the fuel supply to a possible fire, and distance protects you if it spreads. Raising the hood can feed the fire a rush of air.
-
10. What does a traction control system do?
Show answer
Answer A: It limits wheel spin when you accelerate
Traction control cuts power or brakes a spinning wheel so the tires can grip when you pull away or accelerate on a slippery surface.
-
11. You feel dizzy and get a headache while driving with the windows closed. What could be the cause and what should you do?
Show answer
Answer D: An exhaust leak letting carbon monoxide into the cabin, so open the windows and stop to get fresh air
Carbon monoxide is colorless and odorless, and headache, dizziness and drowsiness are early signs. Get fresh air at once and have the exhaust system inspected.
-
12. A wide solid white line separates the through lanes from an exit lane. What does it tell drivers?
Show answer
Answer B: The choice of lane should already have been made
A channelizing line marks where the paths separate and crossing it is discouraged or prohibited, so the lane change has to happen upstream.
-
13. You realize at the last moment that you have passed the street where you meant to turn. What should you do?
Show answer
Answer D: Keep going and turn around where it is safe and legal
A missed turn is a minor inconvenience; braking suddenly, backing up or turning across traffic to recover it causes crashes.
-
14. A parking space is marked with the international symbol of access. Who may use it?
Show answer
Answer A: Only a vehicle displaying the required placard or plate
Accessible spaces may be used only by a vehicle that displays a valid disability placard or plate, no matter how short the stop would be.
-
15. A center lane is bordered by a solid yellow line on the outside and a broken yellow line on the inside, with left-turn arrows painted in it. How may you use that lane?
Show answer
Answer A: Only to make a left turn or to prepare for one from either direction
That marking identifies a two-way left turn lane, which may only be used for left turns or to prepare for a left turn and never for travel or passing.
-
16. A driver ahead brakes for no reason you can see, again and again. What should you do?
Show answer
Answer B: Increase your following distance and be ready for yet another stop
Unexplained braking tells you the driver is unsure or distracted, so the safe answer is more room, not less.
-
17. How can you tell a tire has reached its wear limit without measuring it?
Show answer
Answer C: The wear bars across the grooves become level with the tread
Molded bars sit at the bottom of the grooves. Once the surrounding tread has worn down to them, the tire has reached the end of its safe life.
-
18. You are on a two-lane road where a broken yellow line runs on your side of the center. What does that pattern allow?
Show answer
Answer C: Passing when the way ahead is clear and it is otherwise legal
A broken yellow center line marks a stretch where passing is permitted for traffic on that side when it can be completed safely.
-
19. The queue for an exit ramp has backed up into the right lane of the highway. What should you do if you want that exit?
Show answer
Answer B: Join the back of the queue in the lane instead of cutting in later
Passing a queue and forcing in at the front stops the whole line, and using the shoulder puts you where broken-down vehicles are expected to be.
-
20. On an unlit road, about how far ahead do high beams normally let you see?
Show answer
Answer D: About 350 to 500 feet ahead of the vehicle
High beams light roughly 350 to 500 feet of road and low beams far less, which is why night speeds have to be chosen around the beam, not the limit.
-
21. A lane along the right edge is set off by a solid white line and marked with a bicycle symbol. How should a driver treat it?
Show answer
Answer B: Stay out of it except for the short distance needed to turn or cross where that is allowed
A marked bicycle lane is set aside for bicycle traffic, and motor vehicles may enter it only briefly where turning or crossing is permitted.
-
22. The cars in front of and behind your parallel parked car have left you very little room. How do you get out?
Show answer
Answer D: Ease back and forth, turning the wheels each way, until you clear
Short movements with the wheels turned first one way and then the other walk the car out of a tight space without touching anything.
-
23. What does a posted speed limit sign represent?
Show answer
Answer B: The maximum speed permitted under ideal conditions
A speed limit is an upper limit that assumes good weather, good visibility and light traffic, so the safe speed is often lower than the posted figure.
-
24. What is the function of a regulatory sign?
Show answer
Answer A: To inform road users of traffic laws or regulations that apply at that location
Regulatory signs state requirements that carry the force of law where they are posted, so disregarding one is a violation rather than a lapse of judgment.
-
25. You are driving on an open highway in a strong crosswind. What is the safest adjustment?
Show answer
Answer A: Reduce speed and keep a firm grip, expecting gusts on bridges and beside large vehicles
Gusts hit hardest in open gaps, on bridges and when passing high-sided vehicles, so a lower speed and a firm grip let you correct before you are pushed out of your lane.
