What should you do with headlights when driving in rain or fog?

• A. Turn them off to avoid glare
• B. Use your headlights to improve visibility; in fog use low beams
• C. Use high beams in all conditions
• D. Use hazard lights instead of headlights

Answer: (B)

When visibility is reduced by rain or fog, you should turn on your headlights to help others see you and to better illuminate the road. In fog, use low beams rather than high beams because high beams bounce off the moisture in the air and create glare that actually makes it harder to see. Low beams direct light toward the road and improve contrast, helping you spot lane markings, signs, and other vehicles. Turning off headlights or relying on hazard lights won’t properly illuminate the road, and high beams in fog can impair visibility for you and others.
