Question 1

What should a driver do when driving in heavy fog?

Accepted Answer

Use low-beam headlights, since high beams reflect off fog and reduce visibility — High beams reflect off the water droplets in fog and create glare that shines back at the driver, so low beams actually see farther in fog.

Question 2

What is hydroplaning?

Accepted Answer

A tire losing contact with the road and riding on a layer of water — Hydroplaning happens when water builds up faster than a tire’s tread can channel it away, lifting the tire off the pavement.

Question 3

If a vehicle begins to hydroplane, what is a recommended response?

Accepted Answer

Ease off the accelerator and avoid sudden braking or steering — Sudden inputs can make a hydroplaning vehicle harder to control; easing off the gas lets the tires regain contact with the road.

Question 4

Why is the first rainfall after a long dry spell considered especially hazardous?

Accepted Answer

Oil and dust on the road mix with new rain, creating an especially slick surface — Accumulated road grime combines with the first rain to form a slippery film that hasn’t yet been washed away, making traction worse than in a steady rain.

Question 5

What is a recommended driving adjustment on snow or ice?

Accepted Answer

Reduce speed and increase following distance well beyond normal — Reduced traction on snow and ice means both stopping distance and the risk of skidding increase, so slowing down and leaving extra room is essential.
