Is it recommended to use low beam headlights in fog?

• A. No, high beams should be used.
• B. Only hazard lights should be used.
• C. Do not use headlights.
• D. Yes, use low beams.

Answer: (D)

Fog scatters light and creates glare, so you want illumination that helps you see the road without bouncing back into your eyes. High beams push light far ahead and can reflect off the fog, blurring vision and making it harder for others to see you. Low beams, on the other hand, direct light toward the road at a closer range, illuminating lane markings and hazards without producing excessive glare. If your vehicle has fog lights, they can be used in dense fog to provide extra illumination, but using hazard lights or turning off headlights doesn’t improve visibility. So using low beams is the safest, most effective choice in fog.
