#1. The minimum revocation period for second conviction of driving under the influence is:

If you are convicted of certain criminal traffic violations in DC, including driving while intoxicated or driving under the influence, your minimum revocation period is 6 months for the first offense, 2 year for the second offense, and 3 years for the third or subsequent offense.


#2. When being passed by another vehicle, you must:

If you are driving the vehicle being overtaken, give way to the right in favor of the overtaking vehicle. Do not increase your speed until the passing is completed.


#3. An all-way supplemental plaque is used together with which sign?

Sometimes an All-way plaque is added to a stop sign at an intersection. This means all traffic approaching the intersection must stop.


#4. What does this sign mean?

Side road. A side road enters the highway from the direction shown. Adjust your speed so you can see any vehicles entering or exiting from the side road.

Note: Some versions of the manual have incorrectly shown the added lane sign together with this text for a side road sign.


#5. Unmarked crosswalks are crosswalks not marked by painted lines. They exist:

There is basically a crosswalk at every intersection, even if it is not marked by painted lines.

In the illustration, the area from where sidewalk A ends and sidewalk B begins is a legal crosswalk, even though there are no painted lines. For this reason, it is called an unmarked crosswalk.


#6. When a traffic signal is showing a flashing red light, you must:

A flashing red signal light means stop.

You must come to a complete stop, yield to all other traffic and to pedestrians. Proceed when the way is clear.


#7. While driving, you can listen to music through earphones in both ears:

A person may not wear earplugs, a headset, or earphones attached to a radio, tape player, CD player or other audio device while driving a motor vehicle.

Use of earphones or earplugs for cellular phones are acceptable.

Hearing aid devices are also acceptable.


#8. A three-second or four-second rule is used for:

The best way to assure proper following distance is to use the three-to-four second rule. In many situations you may need more following distance to be safe.

Remember, a four-second following distance does not mean that you are able to stop within four seconds.


#9. What does this sign mean?

Road curves gradually to the left. Be prepared for the change in direction.


#10. What is most important when you adjust to a safe speed?

Posted speed limits do not tell you at what speed to drive. They only tell you what the maximum legal speed is under ideal conditions. By law, you must go slower if conditions make the posted speed limit unsafe. Your speed should depend on things like traffic, road condition, weather, visibility, and the presence of bicyclists or pedestrians.


#11. What does this sign mean?

This is a regulatory No Parking sign. It means that parking is not allowed at any time.

Remember that a red circle with a slash means no. The sign shows you what is not allowed.

You must be able to read and explain all highway signs. The knowledge test consists of several local and highway signs and the DMV examiner will check to see if attention to the signs is paid during the driving test.


#12. Suppose you are driving on a four-lane highway. From which lane should you turn right?

The correct lane for the right turn is the lane furthermost to the right, unless posted otherwise.


#13. If you encounter an aggressive driver on the road:

How to protect yourself from aggressive drivers:

  • Get out of the way and let an aggressive driver pass.
  • Do not challenge an aggressive driver.
  • Avoid eye contact.
  • Always be a courteous driver.

#14. Always turn your front wheels toward the curb when you are parked on a grade and facing:

Headed downhill, turn your front wheels into the curb or toward the side of the road. Set the parking brake.


#15. If you encounter a flooded roadway, you should:

Do not drive through flooded areas. If you see a flooded roadway ahead, turn around and find another route to get to your destination.

Even if the water appears shallow enough to cross, do not attempt to cross a flooded road. Water can hide dips, or worse, floodwaters can damage roadways by washing away the underlying road surface.


#16. If the rear of your vehicle starts to skid left, you should:

Do not panic and do not brake. Take your foot off the gas pedal. Steer in the direction of the skid. If your rear wheels start going to the left, turn your front wheels to the left. Once your car regains traction, straighten out your wheels.


#17. Drivers lingering on the sides of a tractor-trailer:

Always pass a tractor-trailer completely and always on the left side. If you linger when passing any vehicle, your position makes it impossible for the trucker to take evasive action if an obstacle appears in the road ahead.


#18. When an emergency vehicle using sirens or emergency lights approaches, you must:

When you hear or see authorized emergency vehicles, such as police cars, ambulances, and fire engines, you must yield the right-of-way and immediately drive to the curb and stop. You must remain stopped until the emergency vehicle has passed. Never stop in an intersection or roundabout.


#19. A road sign with yellow background indicates:

Yellow is used for general warning and advisory of what to expect ahead.


#20. You approach a stopped school bus on your side of a divided highway. The bus is displaying alternating flashing red lights. In this situation, you must:

When a school vehicle is stopping or has stopped on the roadway, and is operating the alternating flashing red lights, all vehicles must stop at least 20 feet from the front or rear of the school vehicle. No one can proceed until the alternating flashing red lights have been turned off.

Drivers on the other side of a divided highway are not required to stop.


#21. When driving on an interstate or other limited access highway it is generally illegal to:

Stopping on the traveled portion of a highway is prohibited. Stopping on the shoulder is permitted only when your car breaks down or in other emergencies.


#22. On a highway with two-way traffic, you may cross a broken yellow center line:

Keep to the right of a yellow center line. If a broken yellow line is on your side, you may pass if it is safe to do so.


#23. When is it allowed to drive around or under a lowered gate at a railroad crossing?

If the gates are down, stay in place and do not cross the tracks until the gates are raised and the lights stop flashing.


#24. When should you use your high-beam headlights?

Use your high beam headlights whenever possible in open country or dark city streets whenever needed to see persons or vehicles ahead.

Dim your lights when necessary. Do not use high beams in fog, heavy rain, or snow.


#25. If you are driving in fog and conditions are so bad that you can barely see the road ahead:

If the fog is so thick you cannot see well, pull completely off the highway, or stop at a rest area, service station or other parking space. Do not continue driving until you can see well.

Don’t use the practice tests instead of the manual, even if friends and some less committed websites suggest such a strategy. The best way to learn is to put the rules of the road in a context and not simply try to memorize questions and answers.
