1. How should a rider react to a deer or another large animal in the road?
Show answer
Answer B: Brake and prepare to stop, because large animals move unpredictably
A large animal can bolt in any direction at any moment, so the only reliable response is to slow down and be ready to stop.
-
2. How long must a DC applicant wait to retake a failed driver knowledge test?
Show answer
Answer A: Three full calendar days
DC DMV requires three full calendar days before a failed knowledge test can be retaken.
-
3. A pedestrian with a white cane draws the cane back and steps away from the curb as you approach. What does that usually mean?
Show answer
Answer B: They are signaling you to go ahead and drive on
Pulling the cane in and stepping back from the curb is the customary way a blind pedestrian tells drivers to proceed.
-
4. For an alert driver, about how long is the reaction time once a hazard has been recognized?
Show answer
Answer A: About three quarters of a second
Reaction alone takes roughly three quarters of a second for an alert driver, and perception takes about as long again, so a second and a half of travel is added before the brakes bite.
-
5. You are approaching a yield sign on a ramp that joins a busy street. What does the sign require?
Show answer
Answer A: Slow down, be ready to stop, and let the other traffic go first
A yield sign means you must slow, be prepared to stop and give way to traffic on the road you are entering; a full stop is required only when traffic makes it necessary.
-
6. You are driving on a divided highway and see a solid yellow line along the left side of your lanes. What does it tell you?
Show answer
Answer D: It marks the left edge of the roadway for your direction
On a divided highway or a one-way roadway, the left edge of the traveled way is marked with a solid yellow line.
-
7. A vehicle in front of you has already begun turning left into a driveway when the gap you were waiting for opens up. What should you do?
Show answer
Answer B: Wait and let that driver finish the turn
A vehicle that has lawfully started a maneuver keeps the right of way until it is finished.
-
8. You are turning right where a paved trail crosses the road just past the corner. What should you look for?
Show answer
Answer B: Cyclists and walkers arriving from either direction on the trail
A shared use path carries two-way traffic on foot and on bicycles, so scan both directions along the trail before crossing it.
-
9. Why should a driver crossing several lanes change only one lane at a time?
Show answer
Answer B: Each lane has its own traffic and its own blind spot to be checked
Sweeping across two or three lanes means entering lanes you never checked, so each change gets its own signal, mirror check and head check.
-
10. Why is wearing headphones over both ears a problem while driving?
Show answer
Answer D: You may not hear horns, sirens or other warning sounds
Hearing is part of your awareness of traffic. Covering both ears blocks emergency sirens, horns and the sound of an approaching vehicle you cannot yet see.
-
11. You are driving in the left lane at the posted speed limit and a line of vehicles has built up behind you. What should you do?
Show answer
Answer D: Move into a lane on your right when it is safe and let the traffic behind go by
Most states require traffic moving slower than the flow to keep right and reserve the left lane for passing, so a driver holding up a line of vehicles should move right when it is safe rather than block the lane.
-
12. A car in the lane to your left keeps drifting toward the line between you. Which portion of your lane should you move to?
Show answer
Answer A: The right portion
Moving to the far side of your lane buys distance and time if that driver keeps coming, and it may also make the motorcycle visible to a driver who had not noticed it.
-
13. Besides the certification label, what does a novelty helmet typically lack?
Show answer
Answer B: A thick, firm liner of impact absorbing foam under the shell
The energy absorbing layer is what makes a helmet work, and a novelty shell has little or none of it, so it offers almost no protection in a crash.
-
14. Which warning sign keeps its yellow background even when it is used inside a work zone?
Show answer
Answer D: The grade crossing advance warning sign
The round grade crossing advance warning sign keeps its black legend on yellow inside temporary traffic control zones because the railroad hazard it describes is not temporary.
-
15. A line of short dashes set closer together than an ordinary lane line runs beside your lane where a ramp leaves the highway. What does a dotted line of that kind convey?
Show answer
Answer A: A warning that the lane is about to change function
Dotted lines give guidance or warning about a downstream change, such as a lane that becomes an exit only lane or a lane line carried across an intersection.
-
16. You are passing a tractor-trailer on a wet freeway and its wheels throw heavy spray. What is the best technique?
Show answer
Answer B: Increase your wipers and pass steadily without hesitating
Spray blinds you for as long as you stay beside the truck, so prepare the wipers first and then spend as little time in the spray as possible.
-
17. The driver ahead of you is straddling the lane line and is not signaling. How should you respond?
Show answer
Answer B: Stay back until you can see which lane that driver will take
A vehicle astride the line could move either way, so the only safe place is behind it where both possibilities are still covered.
-
18. How should a rider approach a curve whose radius keeps tightening the further you go into it?
Show answer
Answer A: Enter more slowly than the curve first appears to need, saving lean for the exit
In a decreasing radius curve the sharpest part comes last, so a slower entry leaves both speed and lean angle in reserve for where they are needed.
-
19. You are waiting in a center two-way left-turn lane. What should you expect from oncoming traffic?
Show answer
Answer A: Oncoming drivers may enter the same lane to prepare their own left turns
Both directions share a two-way left-turn lane, so an oncoming vehicle may be waiting in it and you must never treat it as yours alone.
-
20. The vehicle ahead of you has pulled out to pass a truck. May you follow it out and pass as well?
Show answer
Answer B: No, wait until it is done and judge the road for yourself
You cannot see past the vehicle ahead of you, and if it has to abort the pass there is nowhere for either of you to go.
-
21. A dog is running toward the road from a yard ahead of you. Why is it a mistake to simply accelerate past it?
Show answer
Answer A: A dog aims at where you will be, so more speed can bring you together
A dog runs at an intercept point rather than at where you are now, which is why the recommended technique is to slow as you approach and then accelerate away once you are beside it.
-
22. What must a DC applicant complete, besides the motorcycle knowledge test, to qualify for the M endorsement?
Show answer
Answer D: A Motorcycle Demonstration Course finished within the last six months
DC DMV requires a Motorcycle Demonstration Course completed within the previous six months in addition to the knowledge test.
-
23. When should a rider use both brakes together?
Show answer
Answer D: Every time the motorcycle slows or stops
Using both brakes for every stop shortens stopping distance and builds the habit the rider will fall back on when a sudden stop is needed.
-
24. What weight does DC law give to an image recorded by an automated traffic enforcement system?
Show answer
Answer D: It is prima facie evidence of the infraction and needs no authentication
DC law makes recorded images prima facie evidence of the infraction and allows them to be submitted without authentication.
-
25. Why is a motorcycle particularly hard for other drivers to judge at night?
Show answer
Answer A: Its single headlight gives no width cues for distance and speed
Drivers judge distance from the spacing between a pair of headlights, and a single lamp gives them nothing to measure, so they routinely misjudge how close and how fast a motorcycle is.
