Which headlight should you use when driving in fog?

• A. High
• B. Low
• C. Parking
• D. Hazard

Answer: (B)

When visibility is reduced by fog, use low beam headlights. Fog scatters light, and high beams will bounce back toward you, creating glare that makes it even harder to see the roadway. Low beams shine the light down toward the road, improving your ability to see lane lines, edges, and hazards while keeping your vehicle more visible to others. Parking lights aren’t bright enough for safe driving, and hazard lights are for emergencies or when you’re stopped, not for normal driving in fog. If your car has fog lights, use them as appropriate, but don’t rely on them alone in place of low beams.
