ELDT Extreme Driving Conditions 3 — Questions and Answers
Question 1: When driving in heavy fog, you should use your:
- Low-beam headlights (Correct answer)
- High-beam headlights
- Hazard lights while moving
- Interior dome light
Correct answer: Low-beam headlights
Low beams reduce glare reflecting back from fog, while high beams make visibility worse.
Question 2: What is the safest action if fog becomes so thick you cannot see the road?
- Pull completely off the road and turn on hazard lights (Correct answer)
- Speed up to get through it faster
- Stop in the driving lane
- Turn off all your lights
Correct answer: Pull completely off the road and turn on hazard lights
Pulling well off the road with hazards on keeps you out of traffic until visibility improves.
Question 3: In heavy rain, hydroplaning is most likely to occur when:
- Speed is high and tires cannot channel water away (Correct answer)
- You drive very slowly
- Tires have deep new tread
- The road is completely dry
Correct answer: Speed is high and tires cannot channel water away
At higher speeds tires ride up on a film of water, losing contact with the road.
Question 4: If your vehicle begins to hydroplane, you should:
- Release the accelerator and hold the steering wheel steady (Correct answer)
- Brake hard immediately
- Turn the wheel sharply
- Accelerate to regain control
Correct answer: Release the accelerator and hold the steering wheel steady
Easing off the gas lets the tires slow and regain contact without sudden steering or braking.
Question 5: During the first hour of rain after a dry spell, roads are especially slippery because:
- Rain mixes with oil and dust to form a slick film (Correct answer)
- The rain washes the road completely clean
- Tires grip better on wet oil
- Water evaporates instantly
Correct answer: Rain mixes with oil and dust to form a slick film
Oil and dirt rise to the surface and mix with water, making the road unusually slippery at first.
Question 6: How should you adjust your following distance in rain or fog?
- Increase it to allow more stopping time (Correct answer)
- Decrease it to stay closer
- Keep it exactly the same
- Eliminate it entirely
Correct answer: Increase it to allow more stopping time
A larger following distance gives extra time to stop safely on wet or low-visibility roads.
Question 7: When it is raining, using your windshield wipers and defroster helps by:
- Keeping the windshield clear for better visibility (Correct answer)
- Increasing your speed
- Cooling the brakes
- Improving tire traction
Correct answer: Keeping the windshield clear for better visibility
Wipers and the defroster keep the windshield clear so you can see hazards in wet weather.
