1. You are behind a slow vehicle on a two-lane road and a marked passing lane begins a mile ahead. What is the sensible choice?
Show answer
Answer D: Wait for the passing lane rather than using the opposing lane
A passing lane lets you overtake without ever entering the lane used by oncoming traffic, which is far safer than a pass a minute earlier.
-
2. Why should the washer reservoir hold proper washer fluid rather than plain water in winter?
Show answer
Answer D: Water freezes and it leaves you with no way at all to clean the glass
Washer fluid contains antifreeze, so it still works in the cold, whereas water freezes in the reservoir and the lines.
-
3. What distance must a DC driver leave when overtaking and passing a bicycle?
Show answer
Answer D: At least three feet
DC requires a driver to leave a safe distance, and in no case less than three feet, when overtaking and passing a bicycle.
-
4. A yield sign is posted where an entrance ramp meets the highway. What must you do?
Show answer
Answer C: Give way to the traffic already on the highway and merge into a gap
The yield sign confirms that the merging driver is the one who must fit into the traffic stream rather than the other way round.
-
5. 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.
-
6. An ambulance with lights and siren is coming toward you on an undivided two-lane road. What must you do?
Show answer
Answer A: Pull to the right edge and stop until it passes
On an undivided road, drivers in both directions clear the way, pulling to the right edge and stopping.
-
7. Warning signs such as stop ahead, yield ahead and signal ahead are installed mainly where
Show answer
Answer B: the traffic control device cannot be seen from far enough away
These advance warning signs are used when a crest, curve or obstruction keeps the stop sign, yield sign or signal from coming into view in time for a driver to react.
-
8. The gates at a railroad crossing are down, and you can see that the road beyond them is clear. What is the correct action?
Show answer
Answer A: Wait until the gates rise completely and the lights go out
Lowered gates mean rail traffic is expected, and driving around them removes the only protection the crossing provides.
-
9. A flagger in a work zone turns a paddle so that the red octagonal face reading STOP is toward you. What must you do?
Show answer
Answer A: Stop completely and wait for the flagger to signal you forward
The STOP face of a flagger paddle requires a complete stop, and you may move again only when the flagger directs you to.
-
10. What must a DC driver do when an authorized emergency vehicle approaches using audible and visual signals?
Show answer
Answer C: Drive to the right-hand edge or curb, clear of any intersection, and stop until it passes
DC regulations require the driver to yield, drive parallel and as close as possible to the right-hand edge or curb, clear of any intersection, and stop until the emergency vehicle has passed.
-
11. You are traveling beside a tractor-trailer and cannot see the truck driver's face in any of the truck's mirrors. What does that tell you?
Show answer
Answer A: The truck driver probably cannot see your vehicle
Large trucks have deep blind spots on all four sides, so if the driver's face is not visible in a mirror the driver has no view of you. Move ahead or drop back until you are out of that area.
-
12. The inside of your windshield keeps fogging up on a cold, damp day. What clears it best?
Show answer
Answer B: The defroster with the air conditioning on, which dries the air
Fog on the inside is moisture from the cabin air. The air conditioner dries that air, and the defroster warms the glass, so together they clear it and keep it clear.
-
13. A driver is following you far too closely and you have a turn coming up. How should you slow down for it?
Show answer
Answer B: Signal early and slow gradually well before the turn
Early signals and gentle braking give a tailgater the time and distance they have failed to leave for themselves.
-
14. In plain words, what is understeer?
Show answer
Answer B: The vehicle keeps going straight even though the wheels are turned
Understeer means the front tires have run out of grip, so the vehicle takes a wider line than the one you steered.
-
15. How does a full load of passengers and luggage affect your braking?
Show answer
Answer B: It lengthens the stopping distance, so you should brake earlier
More weight means more energy to get rid of, so a loaded vehicle takes longer to stop and needs earlier, gentler braking.
-
16. Why should your thumbs rest along the rim rather than hook inside the spokes?
Show answer
Answer D: A jolt can spin the wheel and injure hooked thumbs
A pothole or a dropped wheel can snap the wheel round violently, and thumbs hooked through the spokes are trapped when it happens.
-
17. Where should you be looking as you back into a parallel parking space?
Show answer
Answer B: Over your shoulder through the rear window, glancing all around
Mirrors and cameras leave blind areas, so turn and look through the rear window while checking the front of your car and both sides as it swings.
-
18. An orange background with a black legend on a sign indicates
Show answer
Answer B: a temporary traffic control or work zone situation
Orange is reserved for temporary traffic control signing, so an orange sign means conditions have been altered for work or another temporary operation.
-
19. A driver reaching a stop sign is required to do what?
Show answer
Answer D: Come to a complete stop and then proceed only when it is safe
A stop sign requires a full stop before the stop line, crosswalk or intersection, after which the driver may go on once the way is clear.
-
20. You are turning left from a one-way street onto a two-way street. How should the turn be made?
Show answer
Answer B: Start in the far left lane and finish just to the right of the center line
Left turns begin from the lane nearest the left edge of the street you are leaving and must finish on the right-hand side of the center line of a two-way street.
-
21. How many points does DC assess against a learner permit holder caught driving unaccompanied?
Show answer
Answer A: 5 points
Driving unaccompanied on a learner permit costs 5 points on the DC record, the same as speeding 21 mph or more over the limit.
-
22. A bus stopped at the corner hides the crosswalk you are about to turn across. What should you do?
Show answer
Answer C: Turn slowly, ready to stop for anyone stepping out in front of it
People often step into the road from in front of a stopped bus, so approach the hidden crosswalk slowly and be ready to stop.
-
23. You and the driver facing you both have stop signs at a two-way stop. You are going straight and that driver is turning left. Who has the right of way?
Show answer
Answer B: You do, and the turning driver must wait
Between two opposing drivers who both stopped, the one going straight goes first and the left-turning driver yields.
-
24. Why should you set the parking brake even when an automatic transmission is in Park?
Show answer
Answer B: Because it takes the strain off the transmission and holds the vehicle
The parking pawl is a small part carrying the whole vehicle; the parking brake shares that load and holds the vehicle if the pawl fails.
-
25. A farm implement ahead of you on a two-lane road is wider than its own lane. What should you do?
Show answer
Answer D: Hang back until you can see past it and pass only with a clear road
Wide equipment hides the road ahead and may extend farther across the center line than it appears, so the pass needs more room and a much better view.
