What lights should you use when driving in fog?

• A. High Beams
• B. Hazard Lights
• C. Park Lights
• D. Headlights on Low Beams

Answer: (D)

In fog, you want light that helps you see the road without bouncing back into your eyes. Using headlights on low beams does this: they illuminate the road ahead just enough while staying low enough to avoid creating glare for yourself or other drivers. High beams should be avoided because the light reflects off the fog and creates a wall of glare, making it harder to see. Hazard lights are for emergencies or when you’re stopped, not for driving in fog, and can confuse following drivers. Parking lights are too dim to properly illuminate the road while you’re moving. If your vehicle has fog lights, use them along with the low beams to improve visibility, but never use high beams in fog.
