California DMV Special Driving Conditions

Question 1

When driving in heavy fog in California, you should use:

Accepted Answer

Low-beam headlights or fog lights

Answer

Low-beam headlights or dedicated fog lights project light downward and forward without reflecting back into your eyes in foggy conditions.

Question 2

When driving in rain after a long dry spell in California, roads become especially dangerous because:

Accepted Answer

Oil and grease mix with water to create slippery conditions

Answer

After dry periods, oil and grease accumulate on road surfaces; when first wetted, this mixture creates extremely slippery conditions before rain washes it away.

Question 3

What is hydroplaning and when does it occur?

Accepted Answer

Loss of tire traction when tires ride on a layer of water rather than the road surface

Answer

Hydroplaning occurs when tires travel faster than water can be displaced, causing them to ride on a film of water and lose contact with the road.

Question 4

To prevent or recover from hydroplaning in California, you should:

Accepted Answer

Ease off the accelerator and hold the steering wheel straight

Answer

To recover from hydroplaning, gradually ease off the gas without braking and keep the steering wheel steady until the tires regain road contact.

Question 5

When driving in strong crosswind conditions in California, the greatest danger is:

Accepted Answer

Being pushed out of your lane, especially on bridges or in high-profile vehicles

Answer

Strong crosswinds can push vehicles — especially trucks, SUVs, and motorcycles — sideways, making lane control difficult, particularly on exposed bridges.
