#1. Which of the following is the best method to improve safety when driving at night?

It is wise to slow down a little at night.

#2. Emotions affect your driving. If you feel angry, excited, or upset, you should:

If you are upset or angry, take some time to calm down before driving, or let someone else drive. You would be better off not driving at all when you are emotionally upset.


#3. When a traffic signal is showing a steady green arrow, you:

Proceed with caution only in the direction the arrow points. Remember that you must yield to all pedestrians and vehicles already in the intersection.

When the green arrow is shown in a left-turn signal, it means that opposing traffic is stopped. This is known as a protected turn.

Remember, the green arrow does not mean that all other traffic is stopped by a red light.


#4. This is:

This is an advisory speed sign.

Advisory speed signs have black letters on a yellow or orange background and often are shown under a warning sign.

Advisory speed signs are posted along portions of highways to warn you that conditions may often make it unsafe to drive faster.

Although an advisory speed sign does not have the force of law, if you exceed it and have an accident, it may be concluded that you violated the general speed restriction and are subject to a ticket.


#5. During the first step of parallel parking you should signal, and then stop:

Put on your turn signal to warn other drivers that you intend to park. Pull up until you are even with the car in front of your parking space (back bumpers should be about even). There should be about two or three feet between you and the car beside you.


#6. When must you use your headlights?

By law, you must turn on your headlights one-half hour after sunset and one-half hour before sunrise.

You must turn on your headlights at other times when you cannot see persons or vehicles on the highway clearly at 500 feet or less.

You must also turn on your headlights when the windshield wipers are on.


#7. What does this sign mean?

Winding road. The road ahead is winding with a series of curves or turns. Adjust your speed.


#8. What is true about bicycle riders in District of Columbia?

Bicycles are treated as vehicles in District of Columbia. Bicyclists have rights and duties like those of a motor vehicle.

Bicyclists must ride with the flow of traffic and as near to the right side of the road or street as is safe and practical.


#9. If you plan to turn directly beyond an intersection, you should:

When making a turn just past an intersection, signal once you are in the intersection.


#10. When an emergency vehicle using flashing lights approaches you from behind, 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.


#11. You may cross a double solid yellow line:

Two solid yellow lines between lanes of traffic means neither side can pass. You may cross a solid yellow line to turn into a driveway if it safe to do so.


#12. 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.

#13. In this situation (approaching the bicyclist from behind), you should:

If possible, you should avoid passing other vehicles, including motorcycles and bicycles, on two-lane roads.

Remember, if you are unable to safely pass, reduce your speed, follow the bicycle, and wait for a safe opportunity to pass. In this situation passing on the other half of the roadway is not allowed.

Avoid the use of your horn.


#14. How long will points stay active on your driving record?

Points will stay active on your driving record for two years. Points are automatically removed from your record after two years.


#15. When entering or crossing a city street from a driveway, you must:

When emerging from an alley, driveway, private road, or building across a sidewalk or into a street or highway, you must stop and yield to pedestrians and other vehicles.

Children age 12 and under should ride buckled up in a rear seat in a child safety seat or seat belt appropriate for their age and size.


#17. Which road signs have a green background?

Green and white signs are used for guide information, such as distance or direction.


#18. Before turning left, it is important to:

Make sure it is safe to turn. You must yield to oncoming traffic including bicycles and to pedestrians in crosswalks.


#19. When driving on slippery roads, you should:

Reduce your speed on wet roads and increase your following distance. The best policy is to keep a skid from happening.


#20. This sign added to a stop sign means:

This sign means there are four stop signs at the intersection. Traffic from all directions must stop. The first driver to stop is the first driver to go. Other drivers must wait their turn.


#21. Keeping a safe following distance using a three-second or four-second rule means:

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.


#22. What should you do when you see this sign?

Arrow panels are used both during the day and at night to give advance warning and directional information to tell drivers where it is necessary to move into another lane to the right or left.


#23. If you run off the pavement, you should:

If you run off the road, do not panic. Take your foot off the accelerator. Brake carefully or not at all. Grip the steering wheel tightly. Do not try to get back on the roadway until you have the vehicle completely under control. Speed should be 15 mph or less. Look for traffic behind you and beside you. Then turn the wheels sharply toward the roadway.


#24. You must never park within how many feet of a fire hydrant?

Never park within 10 feet of a fire hydrant.


#25. What does this sign mean?

Reverse turn. The road ahead turns sharply right, then left.
