WA DMV Weather and Hazardous Conditions 2

Question 1

What causes hydroplaning at higher speeds on wet roads?

Accepted Answer

A layer of water builds between the tires and the road surface

Answer

Hydroplaning happens when tires ride on a film of water and lose contact with the pavement.

Question 2

If your vehicle begins to hydroplane, what should you do first?

Accepted Answer

Ease off the accelerator and avoid braking hard

Answer

Easing off the gas lets the tires slow gradually and regain contact with the road without a skid.

Question 3

When is a paved road usually most slippery during rain?

Accepted Answer

During the first 10 to 15 minutes of rainfall

Answer

Early rain mixes with oil and dust on the pavement, creating an especially slick film before it washes away.

Question 4

In heavy fog, which lights should you use while driving?

Accepted Answer

Low-beam headlights

Answer

Low beams aim at the road, while high beams reflect off fog droplets and reduce your visibility.

Question 5

If fog becomes so thick you can barely see, what is the safest action?

Accepted Answer

Pull completely off the road, stop, and turn on hazard lights

Answer

Pulling fully off the roadway and using hazard lights removes you from traffic when visibility is too poor to drive.
