IL DMV IL DMV Special Driving Conditions 1 — Questions and Answers
Question 1: When driving in heavy fog in Illinois, which of the following is the safest action?
- Use high-beam headlights to see farther
- Use low-beam headlights and reduce speed (Correct answer)
- Pull off the road immediately without warning
- Drive in the center of the road
Correct answer: Use low-beam headlights and reduce speed
Low-beam headlights reduce glare in fog, and reducing speed gives more reaction time.
Question 2: When driving on an icy road in Illinois, a driver should:
- Apply brakes firmly to stop quickly
- Accelerate to maintain momentum
- Reduce speed and increase following distance (Correct answer)
- Use cruise control to maintain a steady speed
Correct answer: Reduce speed and increase following distance
Ice requires significantly reduced speed and much greater following distance to stop safely.
Question 3: If your vehicle begins to hydroplane on a wet Illinois highway, you should:
- Steer sharply to regain control
- Apply firm brake pressure
- Ease off the accelerator and hold the wheel steady (Correct answer)
- Shift to a lower gear immediately
Correct answer: Ease off the accelerator and hold the wheel steady
Easing off the gas and keeping the wheel steady lets tires regain contact with the road during hydroplaning.
Question 4: When driving through a flooded roadway in Illinois, the safest action is:
- Drive through quickly to minimize water exposure
- Test the depth with your foot before driving through
- Turn around — never drive into flood water (Correct answer)
- Follow other vehicles that have already crossed
Correct answer: Turn around — never drive into flood water
Just 12 inches of moving water can sweep away most vehicles, so turning around is always safest.
Question 5: In Illinois winter driving, before entering a highway on-ramp after fresh snowfall, a driver should:
- Accelerate quickly to match highway speed
- Test the brakes gently in a safe area first (Correct answer)
- Engage cruise control immediately
- Turn off traction control for better grip
Correct answer: Test the brakes gently in a safe area first
Gently testing your brakes in a safe area helps gauge stopping distance on slippery pavement.
Question 6: When driving in Illinois during a dust storm or blizzard with near-zero visibility, the best action is:
- Turn on hazard lights and continue at low speed
- Pull completely off the roadway, turn off lights, and wait (Correct answer)
- Follow the car ahead as closely as possible
- Drive in the center lane of the highway
Correct answer: Pull completely off the roadway, turn off lights, and wait
Pulling completely off the road and turning off lights prevents other drivers from following your lights into danger.
