The maximum lawful speed in a DC alley is 15 mph, below the 20 mph default that applies to streets.
-
2. 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.
-
3. You are stopped at an intersection where bushes block your view of cross traffic. What should you do?
Show answer
Answer A: Edge forward slowly until you can see, then proceed when clear
Creeping forward a little at a time lets you gain a view without committing to the crossing. Never enter an intersection you cannot see into.
-
4. Where should your hands normally rest on the steering wheel?
Show answer
Answer C: On opposite sides of the wheel, near the 9 and 3 positions
Hands placed opposite each other near the middle of the wheel give smooth, balanced control and keep the arms clear of a deploying air bag.
-
5. When should you turn on your signal before a turn or a lane change?
Show answer
Answer C: Well before the maneuver, so other drivers have time to react
A signal is a warning to others, so it has to be given far enough ahead of the maneuver that drivers and pedestrians can adjust.
-
6. A sign showing a walking figure carries a plaque below it with an arrow slanting down to the right. What does the plaque add?
Show answer
Answer B: The crossing is at that very spot
A downward-slanting arrow plaque marks the crossing itself, whereas an AHEAD or distance plaque would place it further along the road.
-
7. An ambulance has just gone by and traffic starts to move again. Why should you wait a moment before pulling back out?
Show answer
Answer B: Another emergency vehicle may be following the first one
Emergency calls often bring several vehicles, so check that nothing else is coming before you rejoin the traffic lane.
-
8. A barricade carries a sign reading ROAD CLOSED TO THROUGH TRAFFIC. What does it permit?
Show answer
Answer B: Local access for people whose destination is on that road
This closure keeps out drivers who are only passing through while still allowing residents and deliveries to reach addresses within the closed section.
-
9. You have just returned to your own lane after passing. Why should you not slow down straight away?
Show answer
Answer A: The vehicle you passed is close behind and needs room to stop
Returning and then braking leaves the driver you just overtook with almost no following distance, which is how a pass turns into a rear-end collision.
-
10. A school sign paired with a plaque showing a diagonal downward-pointing arrow is installed
Show answer
Answer D: at the school crossing itself, or as close to it as possible
The diagonal downward arrow points at the crossing, so this assembly is placed at the crossing location rather than in advance of it.
-
11. You are in a marked passing zone but a steady stream of oncoming traffic is coming toward you. What does the broken center line allow?
Show answer
Answer C: A pass only when the road is clear, so you have to stay behind
A passing zone marks where the sight distance is adequate, but it never gives permission to enter a lane that another vehicle is occupying.
-
12. What belongs in a basic emergency kit carried in a car?
Show answer
Answer D: A flashlight, a first aid kit, jumper cables and some warning devices
A useful kit lets you see, be seen, treat an injury and restart the vehicle; carrying loose gasoline is a fire risk.
-
13. Which of these makes you unpredictable to other drivers?
Show answer
Answer B: Changing lanes suddenly without signaling, to save a moment
An unsignalled, sudden lane change gives nobody time to react and is a common cause of sideswipe collisions.
-
14. You reach an intersection showing a steady red light, and a stop line is painted across your lane. Where must you bring the vehicle to a complete stop?
Show answer
Answer C: Before the stop line
A steady red requires a complete stop before the marked stop line. Where there is no stop line you stop before the crosswalk, and where there is neither, before entering the intersection.
-
15. You are waiting inside the intersection to turn left when your light turns red. What should you do?
Show answer
Answer A: Complete the turn as soon as the way is clear
Once you have legally entered the intersection you should clear it as soon as the oncoming traffic has stopped, rather than sit in the path of cross traffic.
-
16. You are driving through a long curve on a road with two lanes in your direction. What is correct?
Show answer
Answer A: Stay within your own lane all the way through, adjusting speed before you enter
Wandering out of your lane in a curve puts you into the path of a vehicle you cannot see, and the slowing belongs before the curve rather than in it.
-
17. Your navigation device tells you to turn where a road sign says the turn is closed. What should you do?
Show answer
Answer B: Follow the signs and what you can see
A device works from stored data that can be out of date, while signs and the road in front of you show the situation now, so the road wins every time.
-
18. Who must wear a helmet when riding a bicycle in the District of Columbia?
Show answer
Answer D: Any operator or passenger under 16 years of age
DC makes a bicycle helmet mandatory for any operator or passenger under 16, and strongly recommends one for everybody else.
-
19. What makes up the total distance needed to bring a vehicle to a stop?
Show answer
Answer A: The distance covered while you perceive the hazard, the distance covered while you react, and the braking distance
Total stopping distance combines the ground covered while you notice the hazard, the ground covered while you move your foot to the brake, and the ground covered while the brakes slow the vehicle.
-
20. The route marker used for an Interstate highway is a shield with
Show answer
Answer A: white numerals on a blue field under a red band carrying the word INTERSTATE
The Interstate route marker is a cutout shield with a white border, the word INTERSTATE in white on red across the top and the route number in white on blue.
-
21. Under the DC seat belt law, who has preference for seating positions fitted with belts?
Show answer
Answer D: Passengers aged 16 and under
DC requires the driver to ensure that children aged 16 and under get the belted seating positions ahead of older passengers.
-
22. A driver ahead brakes for no reason you can see, again and again. What should you do?
Show answer
Answer B: Increase your following distance and be ready for yet another stop
Unexplained braking tells you the driver is unsure or distracted, so the safe answer is more room, not less.
-
23. What driving hours apply to a DC provisional license holder during July and August?
Show answer
Answer D: Driving is allowed until 11:59 p.m. every night
During the July and August summer period the provisional limit is 11:59 p.m. every night.
-
24. You are about to descend a long steep grade. How should you control your speed?
Show answer
Answer D: Select a lower gear before starting down and use the brakes in firm, brief applications
Engine braking in a lower gear carries most of the load down the grade, while continuous brake pressure overheats the brakes and reduces their effectiveness.
-
25. You are driving down a parking aisle and reach the main lane that runs along the front of the store. What is the usual rule?
Show answer
Answer C: The main through lane has the right of way over the vehicles leaving the aisles
In a parking lot the wide lane that runs across the ends of the aisles works like a through road, and drivers leaving an aisle yield to it.
