1. Why is being predictable an important part of driving safely?
Show answer
Answer A: Because other road users are able to plan around what you are doing
Other drivers make their decisions from what they expect you to do, so surprises are what produce collisions.
-
2. What does a booster seat do for a child?
Show answer
Answer B: It lifts the child so that the adult belt crosses hips and shoulder
A booster raises the child so the adult belt lies on the strong parts of the body instead of the neck and the abdomen.

4. You have finished a distracting task and your eyes are back on the road. What is true?
Show answer
Answer A: Your full attention takes a while to come back
Studies of drivers show attention lags behind the eyes for many seconds after a phone or a screen task, so the danger continues after the task is over.
-
5. What should you do before leaving a parked vehicle unattended?
Show answer
Answer C: Set the parking brake, place the transmission in park or in gear, switch off the engine and take the key
Securing the vehicle with the parking brake, the transmission and the ignition prevents it from rolling away and from being moved by someone else.
-
6. 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.
-
7. You are already inside an intersection when you realize you should be in the lane beside you. What should you do?
Show answer
Answer C: Stay in your lane through the intersection and change lanes afterwards
Drivers in an intersection are watching for cross traffic and turning vehicles, so an unexpected sideways move there is easily missed.

8. A yellow diamond showing a bicycle is posted on a rural road. What should a driver expect?
Show answer
Answer A: Bicyclists crossing or riding along the roadway there
The bicycle warning sign is used where a bikeway crosses the road or where riders are likely to be in the traffic lanes, so drivers should look carefully and pass wide.
-
9. Small green signs with white numerals posted at regular intervals along a highway are used to
Show answer
Answer B: show distance along the route and give a reference point for reporting a location
Reference location signs, commonly called mileposts, carry white numerals on green and let a driver describe exactly where a breakdown or crash has occurred.
-
10. When may a driver of a motor vehicle use a marked bicycle lane?
Show answer
Answer C: Only to cross it when turning or entering the road where the markings allow
A bike lane is a lane for cyclists. Motor vehicles may only cross it to enter or leave the road or to make a turn where the markings permit.
-
11. The traffic around you is moving well above the limit on a wide highway. What should you do?
Show answer
Answer D: Keep to the limit and stay to the right, letting faster traffic pass
The limit is a legal maximum, and the safe way to differ from the traffic around you is to keep right and let it go by.
-
12. A driver who wants to reverse direction arrives at this sign. What is allowed?
Show answer
Answer C: Going on and reversing direction only where the maneuver is permitted
The restriction removes that maneuver at that spot entirely, so the driver has to continue and turn the vehicle around at a place where it is not prohibited.
-
13. A driver is tailgating you. Why is it a bad idea to tap or stab the brakes to warn them?
Show answer
Answer C: Because it cuts the little space they have and can cause a crash
Brake checking removes the small margin the tailgater has left and can provoke a collision; add space in front of you instead and let them pass.
-
14. A crossing guard steps into the roadway ahead of this sign with one hand raised. What must the driver do?
Show answer
Answer B: Stop and stay stopped until the guard waves traffic on
An adult guard is controlling traffic at that crossing, so the instruction given by that person governs and the driver waits to be released.
-
15. What visual acuity in the better eye does DC DMV accept on its own, with no field of vision condition attached?

Answer D: 20/40
DC DMV accepts 20/40 in the better eye, or 20/70 in the better eye combined with a field of vision of at least 140 degrees.
-
16. A parking space is marked with the international symbol of access. Who may use it?

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.
-
17. The rear of your vehicle begins to slide sideways on a slippery surface. What is the correct correction?
Show answer
Answer C: Ease off the accelerator and steer in the direction you want the front of the vehicle to go
Looking and steering toward your intended path lines the front wheels up with the direction of travel, while sudden braking or a sharp opposite input usually makes the slide worse.
-
18. Which of these is an early warning that you are too tired to keep driving?
Show answer
Answer C: Not remembering the last few miles you drove
Memory gaps, repeated yawning, heavy eyelids and drifting are the body signaling that sleep is winning, and they mean stop rather than push on.
-
19. What is a marked loading zone for?
Show answer
Answer A: Loading and unloading only, not for general parking
A loading zone is reserved for actively loading or unloading goods or passengers; leaving a vehicle there for other reasons is a parking violation.
-
20. You realize you have driven several miles without remembering any of it. What kind of distraction is this?
Show answer
Answer C: Cognitive distraction, because your mind was not on driving
Daydreaming or being lost in thought is a cognitive distraction. Your eyes may be on the road, but your brain is not processing what they see.

22. In a work zone a flagger is directing traffic in a way that conflicts with the posted signs. Whom do you follow?

A flagger controls traffic through a work area that changes from day to day, and those instructions take precedence over the fixed signs and markings in that zone.
-
23. A white diamond symbol is painted in a highway lane. What does it identify?

The diamond symbol marks a preferential lane, most often one reserved for vehicles carrying a minimum number of occupants.

Show answer

A flashing yellow lets you enter the intersection cautiously after yielding to pedestrians and to conflicting traffic that is already there.

25. What do white lane lines painted between travel lanes indicate?
Show answer
Answer A: Traffic in the adjacent lane moves in the same direction as you
White markings separate lanes carrying traffic in the same direction and mark the right edge of the roadway.
