1. Traffic ahead of you has stopped in your lane while the next lane is still moving. What is the first thing to do?
Show answer
Answer C: Slow down first and check the next lane before moving over
Braking is the action that keeps you from hitting the stopped traffic, and the lane change is only safe once you have looked.
-
2. A sign at the start of an exit ramp shows a speed much lower than the highway limit. What does it apply to?
Show answer
Answer C: The curve of the ramp itself, once you have left the highway
The ramp speed is set by the sharpness of the ramp curve, so you slow to it inside the deceleration lane rather than out on the highway.
-
3. You are driving on a two-lane road approaching the crest of a hill. Where should you position your vehicle?
Show answer
Answer D: Toward the right side of your lane, in case an oncoming vehicle is over the center line
You cannot see what is beyond a crest, and oncoming drivers sometimes drift across the center. Keeping right and slowing gives you a margin.
-
4. Your low beams light about 250 feet of road, but at your speed you would need more than that to stop. What is that called?
Show answer
Answer D: Overdriving your headlights
When your stopping distance is longer than the stretch of road your headlights show, you cannot react to anything you finally see. Slow down until you can.
-
5. You have stopped on the shoulder of a busy freeway with a flat tire that you cannot change safely. Where should you and your passengers wait?
Show answer
Answer A: Well away from the traffic side, behind a barrier or up the bank if there is one
People struck on the shoulder are a common cause of roadside deaths, so wait away from the traffic side and behind any barrier.
-
6. Beside an accessible parking space there is an area painted with diagonal stripes. What is it for?
Show answer
Answer C: It is an access aisle for wheelchairs and lifts, and no vehicle may park or stop in it
The striped access aisle gives the room a ramp or lift needs to deploy, so blocking it makes the adjacent accessible space unusable.
-
7. You reach a stretch of road covered by moving flood water of unknown depth. What is the correct decision?
Show answer
Answer D: Turn around and take another route
About a foot of moving water is enough to carry away most cars, and the roadbed under the water may already be washed out, so the only safe choice is to turn around.
-
8. Where does the restriction that starts at this sign come to an end?
Show answer
Answer D: Where the centerline markings show that overtaking is allowed again
The sign marks the start of the restricted section, and the centerline markings along the road show how far it runs and where overtaking becomes lawful again.
-
9. Two solid white lines are painted between your lane and the lane beside it. What do they mean?
Show answer
Answer D: Crossing from one lane to the other is prohibited
Double solid white lines separate lanes of traffic going the same way and may not be crossed.
-
10. 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.
-
11. A blue motorist service sign showing a fuel symbol and an arrow means that
Show answer
Answer D: fuel is available in the direction shown, and the sign imposes no obligation
Service signs are informational: they tell the driver what is available and in which direction, but they create no requirement.
-
12. What happens to your field of vision as your speed increases?
Show answer
Answer C: It narrows, so you notice less at the sides of the road
The faster you travel, the more your useful field of view narrows toward the center, so a hazard coming from the side is seen late or missed altogether.
-
13. What is the purpose of carrying a first aid kit in your vehicle?
Show answer
Answer D: It lets you treat cuts and bleeding while the help is on its way
A kit is for simple first aid such as controlling bleeding until trained help arrives, not a substitute for calling for that help.
-
14. How should a driver respond to this sign?
Show answer
Answer C: Slow down before reaching the rough spot and cross it at a steady, low speed
Losing speed before a sharp rise in the pavement keeps the vehicle settled, while braking or accelerating on top of it unsettles the suspension and costs grip.
-
15. What is the benefit of looking far down the road rather than just ahead of the hood?
Show answer
Answer A: You steer with smaller corrections and you see trouble in plenty of time
A distant view steadies your steering and gives you time to plan, because you meet hazards after you have already seen them.
-
16. A sign with a blue background and a white legend and border tells road users about
Show answer
Answer A: services such as fuel, food, lodging, hospitals and rest areas
Blue is the background of the general service series, which points travelers toward the services available along or near the route.
-
17. What should a driver do first after passing this sign?
Show answer
Answer A: Move into the right-hand lane and stay there
Traffic returns to two-way operation, so the driver keeps to the right of the centerline and stops treating the left side as available.
-
18. You are parked legally, but a police officer tells you to move the vehicle. What should you do?
Show answer
Answer B: Move it as directed, because an officer overrides the signs
Directions from a police officer or a firefighter take precedence over signs and markings, whether they are directing traffic or clearing a street.
-
19. An arrow panel at a work zone displays a flashing arrow pointing to the left. What does it require?
Show answer
Answer C: Move out of the closed lane into the lane on the left
A flashing or sequential arrow on an arrow panel directs traffic out of a closed lane and into the lane the arrow points to.
-
20. 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.
