When driving in fog, what lights should you use?

• A. High beams
• B. Fog lights or dipped headlights
• C. No lights, as it's daytime
• D. Turn signals

Answer: (B)

Using fog lights or dipped headlights when driving in fog is essential for safety and visibility. Fog can significantly reduce visibility, making it difficult to see other vehicles, road signs, and to be seen by other drivers. High beams can actually cause a glare when reflecting off the water droplets in fog, making conditions worse instead of better. Fog lights are specifically designed to cast a wide, low beam that cuts through the dense moisture in the air, illuminating the road immediately in front of the vehicle without causing excessive reflection. Dipped headlights also provide a safer alternative to high beams, by allowing for better visibility without blinding other drivers. It's crucial to avoid relying solely on daytime driving as well; even during the day, fog can obscure visibility enough that using lights is necessary to ensure safety for both the driver and others on the road.
