RTA Driving in Adverse Conditions 3

Question 1

What is hydroplaning, and when is it most likely to occur?

Accepted Answer

Loss of tire contact with the road due to water; most likely at high speeds in rain

Answer

Hydroplaning happens when water builds up faster than tires can disperse it, causing the vehicle to ride on a water film at higher speeds.

Question 2

During a whiteout blizzard, if you must pull over, you should:

Accepted Answer

Pull completely off the road and keep your lights on so others can see you

Answer

Pulling fully off the road and keeping lights on prevents other vehicles from colliding with your stopped car.

Question 3

Which action is LEAST effective when driving on snow-covered roads?

Accepted Answer

Applying cruise control to maintain a steady speed

Answer

Cruise control can cause a vehicle to accelerate to regain speed after a slip, worsening loss of traction on snow.

Question 4

When visibility drops below a safe level due to blowing dust or sand, the first thing you should do is:

Accepted Answer

Reduce speed, turn on headlights, and pull off the road if needed

Answer

Slowing down, using headlights, and exiting the roadway if necessary are the safest responses to a dust storm.

Question 5

What effect does tire pressure have on driving in cold weather?

Accepted Answer

Tire pressure decreases in cold temperatures, affecting traction and handling

Answer

For every 10°F drop in temperature, tire pressure drops about 1 PSI, which can reduce traction and fuel efficiency.
