In heavy fog, a safe practice is to:

• A. Increase your speed to pass quickly
• B. Drive with hazard lights on at all times
• C. Reduce your speed and use low beam headlights
• D. Use high beams

Answer: (C)

In fog, the main goal is to maximize your ability to see the road while keeping glare to a minimum. Fog scatters light, so lowering your speed gives you more time to notice hazards and react. Using low beam headlights helps because they illuminate the road directly ahead without bouncing off the fog and creating a harsh glare that can wash out your vision. High beams, by contrast, reflect off the fog and make it harder to see, turning the road into a bright wall. Hazard lights aren’t appropriate for normal driving in fog because they can confuse other drivers and don’t improve your own visibility. So slowing down and using low beams is the safest approach in heavy fog.
