2. What is hydroplaning?

Improves vehicle control in rainy conditions

Prevents skidding in wet weather

Increases traction on wet roads

Hydroplaning is the loss of traction when driving on wet surfaces, resulting in loss of braking and steering control. It occurs when a buildup of water between the tires and road surface causes the tires to lose contact with the road.

3. Is it safe to use cruise control in snowy conditions?

Not recommended

Partially true

True

False

Using cruise control in snowy conditions can lead to loss of control over the vehicle as it may not respond quickly enough to sudden changes in road conditions.

Explanation

Using cruise control in snowy conditions can lead to loss of control over the vehicle as it may not respond quickly enough to sudden changes in road conditions.

4. Approximately what percentage of our driving clues depend on vision?

85%

60%

75%

90 %

Vision plays a crucial role in driving as approximately 90% of our driving clues depend on it. This includes seeing road signs, other vehicles, pedestrians, and potential hazards.

5. What does overdriving your headlights mean?

You are using high beam headlights in a well-lit area

Your headlights are too bright for other drivers to handle

You cannot stop in the distance illuminated by your headlights

You are driving too fast for the road conditions

Overdriving your headlights means that you are unable to stop in the distance illuminated by your headlights, which can increase the risk of a collision as you may not be able to react in time to obstacles or hazards in the road ahead.

Explanation

Overdriving your headlights means that you are unable to stop in the distance illuminated by your headlights, which can increase the risk of a collision as you may not be able to react in time to obstacles or hazards in the road ahead.

6. When is a wet roadway most slippery?

During a light drizzle

When the rain first begins

On a warm sunny day

After a heavy downpour

A wet roadway is most slippery when the rain first begins because the water combines with the oils on the road surface creating a very slick surface. While a heavy downpour can also make the road slippery, the initial rain is when the road is likely to be at its most treacherous.

7. When driving at night with low beam headlights, the maximum safe speed is ______.

30

55

60

45

When driving at night with low beam headlights, the maximum safe speed is reduced to ensure proper visibility and reaction time. It is important to drive at a speed that allows you to stop within the distance illuminated by your headlights.

Explanation

When driving at night with low beam headlights, the maximum safe speed is reduced to ensure proper visibility and reaction time. It is important to drive at a speed that allows you to stop within the distance illuminated by your headlights.

8. Bridges tend to freeze before road surfaces due to certain factors. Is this statement true or false?

Depends on the weather conditions

True

Sometimes true, sometimes false

False

Bridges freeze before road surfaces because they are exposed to cold air on both the top and bottom, causing them to lose heat more quickly. This difference in exposure speeds up the cooling process and leads to faster ice formation compared to road surfaces.

9. In fog, you should use _____?

Low beam lights

Hazard lights

High beam lights

Fog lights

In foggy conditions, using low beam lights is advisable as high beam lights can reflect off the fog and impair visibility. Fog lights are specifically designed for use in foggy conditions. Hazard lights should only be used when a vehicle is stationary or in an emergency situation.

10. Dirty headlights can reduce visibility up to 90%.

Uncertain

False

True

Partially true

Dirty headlights can indeed reduce visibility significantly, up to 90% in some cases. This is why it is important to regularly clean and maintain headlights to ensure optimal visibility while driving at night or in poor weather conditions.

11. If you suffer from night blindness, what should you avoid doing?

You should wear darker sunglasses during the day

You should stop eating carrots

You should not drive at night

You should increase the brightness of your phone screen

Night blindness is a condition where it is difficult or impossible to see in low light situations. Driving at night can be dangerous for individuals with night blindness, as their vision may be impaired leading to potential accidents.

12. Virginia law requires the use of headlights whenever the windshield wipers are in use.

True

Not specified in Virginia law

False

Only required during nighttime

In Virginia, it is a law that whenever the windshield wipers are in use, headlights must also be turned on for increased visibility and safety, regardless of the time of day.

13. Will using the air conditioner help defog interior windows?

Partially true

True

Depends on the weather

False

Using the air conditioner helps to reduce the humidity inside the car, which in turn helps prevent interior windows from fogging up. The air conditioner works by cooling the air and removing moisture, making it easier to maintain clear visibility while driving.
