#1. When driving past this sign:

You are going the wrong way. Turn around immediately.

Remember, the wrong way sign is a supplement to the do not enter sign. It is placed along the exit ramp or the one-way roadway farther from the crossroad. It tells you that you have already entered a one-way road and are driving in the wrong direction.


#2. Know signs by their shapes. The octagon (eight-sided) shape is used for:

This shape indicates stop. Stop and give the right-of-way to pedestrians and all cross traffic before moving forward.


#3. When passing a tractor-trailer, you should avoid:

Do not linger alongside a truck when passing. Always pass a large vehicle 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.

This question asked what you should not do.


#4. Which car or cars are best positioned for a right turn on this one-way street?

A right turn should be from the right lane into the right lane of the roadway entered.


#5. When it is safe to do so, a broken yellow center line may be crossed:

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.


#6. Which is background color on a warning sign like this?

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


#7. When your car has an enabled front passenger air bag, a rear-facing infant seat must:

Infants should never ride in the front seat of a vehicle with a passenger-side air bag. Remember, all children 12 and under should ride in a rear seat.


#8. What is true about tailgating (following another vehicle too closely)?

Most rear-end collisions are caused by following too closely.


#9. You may park and leave your car in front of a barricade that has been placed for the purpose of closing the street:

Parking is not allowed in front of any barricade or sign that has been placed for the purpose of closing the street.


#10. Which of the following must you obey over the other three?

You must follow orders of police officers, the direction of firefighters in emergency situations, the direction of flaggers in work zones, and any authorized school crossing guard.

Remember, school-crossing guards, have the authority to stop, control and guide vehicular traffic.


#11. The driver in front of you signals (left arm extended downward, with palm of hand to the rear):

Slowing or stop – left arm extended downward, with palm of hand to the rear.


#12. If the pavement is wet as you approach this sign, it is dangerous to:

Slippery when wet.

This section of highway is more slippery than other roads when wet. Reduce your speed.


#13. What is the first thing you should do when your car starts to skid?

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


#14. Which is one factor that greatly affects your stopping distance?

Your actual stopping distance will depend upon many factors, including:

  • Your perception and reaction time.
  • Type and condition of the pavement.
  • Percentage of grade of roadway.
  • Kind and condition of tire treads.
  • Vehicle design and condition of shock absorbers.
  • Type and condition of brakes.
  • Direction and speed of the wind.

Note: a posted speed limit does not affect the stopping distance, only your actual speed does. Speed limits do not tell you at what speed you should drive. They only say you cannot go faster than the speed shown.


#15. You are driving on a road with few streetlights on a clear night. If you cannot see well with your low-beam headlights, which of these actions would help?

Use high beams in open country when there are no oncoming vehicles.

Dim your lights when necessary.


#16. When you approach a traffic signal displaying a steady yellow light, you must:

A steady yellow light means caution, the signal is changing from green to red. Its purpose is to provide time for approaching traffic to stop safely and to clear other vehicles from the intersection before the light turns red.

You must stop if you can do so safely. The law says: Vehicular traffic shall stop before entering the nearest crosswalk of the intersection, unless so close to the intersection that a stop cannot safely be made.


#17. If you drive in a manner that indicates a willful disregard for the safety of people or property, you are guilty of:

A person is guilty of reckless driving if he drives a motor vehicle with a willful disregard for the safety of people or property, or in a manner that indicates a willful disregard for the safety of people or property.


#18. When merging onto a limited access highway:

Whenever you merge with traffic, be sure to signal well in advance and try to enter at the same speed that traffic is moving.

Always check your blind spots before starting to move into another lane.


#19. An arrow panel displaying either of the following messages means:

Caution. An arrow panel displaying either of the following messages indicates there is a work area ahead adjacent to the travel lane and to drive with extra caution.

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.


#20. What does this sign mean?

Divided highway ahead (divided highway begins).

The highway ahead is divided into two one-way roadways. Keep to the right.


#21. Why is it wise to slow down a little at night?

It is wise to slow down a little at night.

At night, you do not see as far, as soon, or as much and everything has a different appearance. Keep your speed low enough to be able to stop within the distance you can see ahead.


#22. When you approach a railroad crossing without warning signals, stop signs or crossing gates:

You must yield to train traffic. Trains cannot stop quickly. Trains are always moving much faster than they appear from a distance so drivers should never try to beat one.


#23. As you approach the top of a hill, you should:

You must slow down when coming to an intersection, railroad grade crossing, curve, or the crest of a hill. If you cannot see over the top of a hill, slow down to an appropriate speed until you crest the hill and regain sight of the roadway.


#24. When two vehicles from different directions arrive at the same time at a four-way stop, which one must yield?

At four-way stops, the first vehicle to stop should move forward first. If two vehicles reach the intersection at the same time, the driver on the left yields to the driver on the right.


#25. If you reach 10 or 11 points on your driving record, your driver's license will be automatically:

If you accumulate 10 or 11 points, your DC license will be suspended, and you will lose your driving privileges for a period of 90 days.
