1. A curb sign reads 2 Hour Parking, 8 AM to 6 PM, Monday to Saturday. When may you stay longer than two hours?
Show answer
Answer A: Outside those hours and on Sundays
A time limit applies only during the days and hours printed on the sign; outside them the ordinary parking rules apply.
-
2. A streetcar is coming along tracks in the middle of the street as you wait to turn across them. What should you do?
Show answer
Answer A: Let the streetcar pass before you cross the tracks
Rail vehicles cannot steer around you and need a long distance to stop, so drivers yield to a streetcar or light rail train.
-
3. From which lane should a permitted U-turn be started?
Show answer
Answer A: The lane nearest the center line, the same one used for a left turn
A U-turn is begun from the far left lane for your direction, the same position used for a left turn, so you do not cut across traffic beside you.
-
4. You park facing downhill on a one-way street where the curb is on your left. Which way do the front wheels go?
Show answer
Answer A: Left, toward the curb on that side
Standard practice follows the curb rather than the side of the road: facing downhill the wheels point into the curb so a rolling vehicle is stopped by it. States differ on whether this is legally required.
-
5. How does heavy cargo on a roof rack change the way a vehicle handles?
Show answer
Answer D: It raises the center of gravity, so the vehicle tips more in turns and needs gentler steering
Weight carried high makes the vehicle lean more and roll over more easily, and extra weight lengthens stopping distance. Drive slower and steer smoothly with a loaded roof.
-
6. The circular sign shape is reserved for which warning?
Show answer
Answer C: Advance warning of a highway-rail grade crossing
A round yellow sign with a black X and the letters RR is the grade crossing advance warning sign, and the circular outline is used for no other message.
-
7. 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.
-
8. Is dictating a message by voice a safe alternative to typing one?
Show answer
Answer C: No, it still takes attention from driving
Composing and checking a spoken message loads the mind and usually pulls the eyes to the screen anyway, so research finds it no safer than other phone use.
-
9. 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.
-
10. How long must a DC learner permit be held before the holder can apply for a provisional license?
Show answer
Answer B: At least 6 months
A DC applicant must hold a valid learner permit for at least 6 months before applying for a provisional license.
-
11. 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.
-
12. 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.
-
13. You are approaching a refuse collection truck working along your street. What should you expect?
Show answer
Answer D: Workers stepping into the road around the truck
Collection crews move constantly between the truck and the curb, often from where you cannot see them, so slow right down and pass only when the whole area is clear.
-
14. You have just passed a vehicle on a two-lane road. When may you return to your lane?
Show answer
Answer B: When you can see the whole vehicle in your inside mirror
Seeing the entire vehicle you passed in your rearview mirror shows there is room to pull back in without cutting it off.
-
15. A steady downward green arrow is displayed over a lane. What does it indicate?
Show answer
Answer C: The lane is open to traffic in your direction
A steady downward green arrow means the lane it points to is open to traffic traveling in your direction.
-
16. Freeway traffic ahead of you has come to a stop. Besides braking early, how can you warn the drivers behind you?
Show answer
Answer B: By switching on the hazard lights for a few seconds
A short burst of hazard lights is a recognized way to tell following traffic that the queue ahead has stopped, and it carries much further back than brake lights. Some states restrict hazard lights on a moving vehicle, so use them only for the moment you are slowing.
-
17. The signal ahead turns yellow while you are approaching it. What does the yellow light mean?
Show answer
Answer C: The red is coming; stop if you can do so safely
A steady yellow warns that the red is next. Stop if you can do so safely; enter the intersection only when stopping would be dangerous.
-
18. You are calling 911 to report a crash. Which information matters most?
Show answer
Answer C: The exact location, how many people are hurt and any hazard such as fire
Dispatchers need to know where to send help, how much help to send, and what dangers the crews will meet on arrival.
-
19. Well before an intersection, an overhead sign shows a diagram of the lanes with an arrow above each one. What is its purpose?
Show answer
Answer C: To let drivers pick the correct lane in good time
Advance intersection lane control signs display the lane assignment far enough back that drivers can move over calmly instead of at the last moment.
-
20. 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.
-
21. You carry reflective warning triangles in your car. How should they be used after a breakdown?
Show answer
Answer B: Set out behind the vehicle, far enough back to warn traffic before it arrives
A warning device works only if drivers see it in time to react, so it is placed well back along the road they are traveling.
-
22. You have parked a manual transmission car facing downhill. Which gear should you leave it in?
Show answer
Answer D: Reverse, along with the parking brake set firmly
Facing downhill the car would roll forward, so reverse gear opposes that movement while the parking brake and turned wheels back it up.
-
23. What does electronic stability control do that ordinary brakes cannot?
Show answer
Answer C: It brakes single wheels to bring the vehicle back on your intended path
The system compares where you have steered with where the vehicle is actually going, then brakes individual wheels to pull it back into line.
-
24. What is a microsleep?
Show answer
Answer D: A few seconds of sleep, sometimes with the eyes open
A microsleep is an involuntary lapse of a few seconds during which the driver is asleep and the vehicle travels blind, often without the driver knowing.
-
25. On dry pavement in good weather, what is the smallest following gap you should keep?
Show answer
Answer A: About three seconds behind the vehicle ahead
Three seconds is the accepted minimum on dry roads in good visibility, and the gap should be longer in poor conditions.
