When driving in fog, which headlights should you switch on?

• A. High beams
• B. Low beams
• C. Hazard lights
• D. Standby lights

Answer: (B)

In fog, glare from lights can bounce off the tiny droplets and wash out your vision. High beams shoot light farther ahead, but that extra distance just reflects back into your eyes from the fog, making it harder to see. Low beams direct light downward toward the road, reducing that glare and helping you see the lane lines, shoulders, and any hazards close in. Hazard lights are for emergencies or when you’re stopped, and they can confuse other drivers. Standby or parking lights aren’t meant for normal night driving visibility in fog. So, using low beams is the safer, more effective choice.
