1. A police officer is directing traffic at an intersection and waves you through a red light. What should you do?
Show answer
Answer C: Follow the officer, whose directions come before signs and signals
Directions given by a police officer or an authorized flagger override signs, signals and pavement markings.
-
2. You are overtaking in a short passing lane on a two-lane road and it is about to end. What must you do?
Show answer
Answer A: Finish the pass and move back to the right before it ends
The added lane ends and the traffic returns to a single lane in each direction, so the pass has to be complete before the pavement runs out.
-
3. A curb lane is marked BUS ONLY 7 AM TO 9 AM. What may the driver of a car do?
Show answer
Answer A: Use the lane outside those hours
A part-time bus lane is reserved only during the posted period, and outside it the lane serves general traffic like any other.
-
4. A pedestrian is crossing at a corner where no crosswalk is painted on the pavement. What is your duty?
Show answer
Answer A: Yield, because a legal crosswalk exists at the corner even without paint
Every intersection has a crosswalk whether or not it is marked, and drivers must yield to pedestrians crossing there.
-
5. You are on a two-lane road where a broken yellow line runs on your side of the center. What does that pattern allow?
Show answer
Answer C: Passing when the way ahead is clear and it is otherwise legal
A broken yellow center line marks a stretch where passing is permitted for traffic on that side when it can be completed safely.
-
6. You are about to pass a large truck on a two-lane highway. Which practice is correct?
Show answer
Answer A: Finish the pass without delay and expect wind turbulence beside the truck
Lingering beside a truck keeps you in its blind spot and exposes you to air turbulence. Pass on the left, keep moving, and move back only when you can see the whole truck in your mirror.
-
7. A person using a wheelchair is waiting to cross at a corner ahead. How should you treat that person?
Show answer
Answer B: As a pedestrian with the right of way at the crossing
A wheelchair or a mobility scooter user has the rights of a pedestrian, so yield the whole crossing and wait until the crossing is finished.
-
8. A yellow diamond showing arrows arranged in a circle warns of
Show answer
Answer B: a circular intersection such as a roundabout ahead
The circular intersection warning sign announces a roundabout or traffic circle so drivers can slow down and prepare to yield to traffic already circulating.
-
9. You are waiting to turn and the traffic ahead has stopped. Where must you not come to rest?
Show answer
Answer D: On the crosswalk, which people need in order to cross the street
Stopping on a crosswalk forces pedestrians out into the traffic lanes to get around you, so you hold back before it instead.
-
10. How should a lap and shoulder belt be positioned?
Show answer
Answer A: Lap belt low across the hips and shoulder belt across the chest and collarbone
The lap belt must bear against the strong pelvic bones rather than soft organs, and the shoulder belt must cross the rib cage and collarbone so crash forces spread over the skeleton.
-
11. How long does a new DC resident have to register a vehicle with DC DMV?
Show answer
Answer D: 60 calendar days from the date residency begins
A new resident has 60 calendar days from starting to live in DC to register the vehicle, after first converting the out-of-jurisdiction driver license.
-
12. What does DC law forbid when a bus is stopped at a bus stop located at an intersection?
Show answer
Answer D: Passing to the left of the bus and pulling in front of it to turn right
DC prohibits passing to the left of a bus and pulling in front of it to make a right turn when the bus is at a bus stop at an intersection; drivers must stay or merge behind it.
-
13. 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.
-
14. Which shape is used for the school advance warning sign and the school crossing sign?
Show answer
Answer B: An upward-pointing pentagon
The five-sided pentagon with its point up identifies school signing, so the outline alone tells a driver that children may be present.
-
15. Two solid yellow lines are painted down the center of a two-way road. What do they mean?
Show answer
Answer B: Traffic in neither direction may cross them to pass
A double solid yellow line marks a no-passing zone that applies to traffic traveling in either direction.
-
16. Why is heavy braking a poor idea while two wheels are still on a soft shoulder?
Show answer
Answer B: The two sides have different grip, so the vehicle can pull sharply
With one pair of wheels on pavement and the other on loose material, hard braking slows one side more than the other and swings the vehicle around.
-
17. What is the consequence of being caught cheating on a DC DMV knowledge test?
Show answer
Answer C: No retest for 60 days
An applicant caught cheating on the DC knowledge test cannot retest for 60 days.
-
18. What is the purpose of a wide solid white line painted straight across your lane on the approach to an intersection?
Show answer
Answer C: It shows the point where a required stop must be made
A stop line indicates the point at which the stop required by a signal or a stop sign is to be made, ahead of the crosswalk and the intersection.
-
19. In normal operation, which indication always comes between a green and a red on the same signal face?
Show answer
Answer C: A steady yellow
The yellow change interval must follow every green or green arrow, so a signal can never jump straight from green to red.
-
20. 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.
-
21. What does black ice usually look like from the driver seat?
Show answer
Answer C: A patch of pavement that simply looks wet or slightly glossy
Black ice is clear, so you see the dark road through it and read it as a wet patch. In freezing weather, treat any wet looking patch as ice.
-
22. What should a driver expect a short distance beyond this sign?
Show answer
Answer C: Another road crossing the one being traveled
Traffic may enter or cross from either side at the intersection ahead, so the driver should ease off, cover the brake and check both approaches.
-
23. 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.
-
24. A black on white regulatory sign at an intersection reads NO TURNS. What may a driver do there?
Show answer
Answer B: Only continue straight through the intersection
The NO TURNS sign bans turns in every direction at that intersection, so the only lawful movement from that approach is straight through.
-
25. A left-turn bay opens ahead of the intersection with a solid white line beside it. Where should you enter the bay?
Show answer
Answer C: At the opening before the solid line begins
The solid line marks where lane changes are no longer intended, so you move into the turn bay at its opening rather than cutting across the line later.
