ICBC British Columbia Written Exam Practice Test 2025

What action should you take when driving in foggy conditions?

1. Use high beam headlights and accelerate

2. Use low beam headlights and reduce speed

3. Turn off headlights and drive cautiously

4. Use hazard lights and drive at normal speed

The correct answer is: Use low beam headlights and reduce speed

When driving in foggy conditions, it is essential to use low beam headlights and reduce speed. Low beam headlights are designed to illuminate the road directly in front of your vehicle without causing glare that can reflect off the fog, which would impair your visibility even further. By using low beams, you can see more clearly, and other drivers can see you more easily as well. Reducing speed is crucial because fog can create deceptive visibility conditions. What might seem like a safe distance or a clear path can quickly change, so driving at a slower speed gives you ample time to react to obstacles or changes in the road. This combination of using the appropriate lights and driving at a cautious speed helps ensure your safety and the safety of others on the road under limited visibility conditions. In contrast, using high beam headlights in fog will create a blinding effect, making it harder to see. Turning off headlights is dangerous as it can make your vehicle less visible to others. Utilizing hazard lights while driving at normal speed does not adequately address the reduced visibility and can also confuse other drivers about your intentions.
