CLP Driving in Adverse Conditions 2 — Questions and Answers
Question 1: When driving in fog, which headlight setting should you use?
- High beams
- Low beams (Correct answer)
- Parking lights only
- Four-way flashers only
Correct answer: Low beams
Low beams should be used in fog because high beams reflect off fog droplets and reduce visibility further.
Question 2: If fog becomes so thick you cannot see well enough to drive safely, what should you do?
- Continue driving very slowly with flashers on
- Pull completely off the road and use only hazard flashers (Correct answer)
- Pull to the shoulder and keep all lights on full
- Increase speed to clear the fog zone quickly
Correct answer: Pull completely off the road and use only hazard flashers
In extremely dense fog, you should pull completely off the road and use only hazard flashers to avoid attracting other drivers toward your vehicle.
Question 3: When your vehicle is stopped due to fog, which signals should you use to alert approaching drivers?
- Leave headlights on high beam
- Activate four-way hazard flashers (Correct answer)
- Sound your horn at regular intervals
- Leave only parking lights on
Correct answer: Activate four-way hazard flashers
Four-way hazard flashers alert approaching drivers to your position without the blinding or attracting effect of headlights aimed down the road.
Question 4: In conditions of reduced visibility such as fog, what adjustment should you make to your driving?
- Maintain the posted speed limit to stay with traffic flow
- Reduce speed and increase following distance (Correct answer)
- Reduce speed only when approaching curves
- Keep speed constant to maintain vehicle stability
Correct answer: Reduce speed and increase following distance
Reduced visibility requires lower speeds and greater following distance to allow adequate reaction and stopping time.
Question 5: Smoke from a wildfire or industrial source creates driving hazards most similar to which condition?
- Heavy rain
- Black ice
- Dense fog (Correct answer)
- High crosswinds
Correct answer: Dense fog
Smoke reduces visibility in ways similar to dense fog and requires the same precautions, including low beams and reduced speed.
Question 6: When approaching a foggy area on the highway, what should you do before entering it?
- Accelerate to get through the fog zone quickly
- Slow down before entering the fog (Correct answer)
- Switch to high beams before entering
- Maintain your current speed to match surrounding traffic
Correct answer: Slow down before entering the fog
You should reduce speed before entering a foggy area so you have adequate control and visibility margin once inside.
