When driving in fog, what type of headlights should you use?

Using low beam headlights in foggy conditions is essential for maintaining visibility while ensuring safety. High beam headlights can actually create more glare and make it harder to see because the light reflects off the moisture in the fog, causing a washout effect. This blinding glare can obscure your vision and that of other drivers, increasing the risk of accidents.

Low beam headlights provide enough illumination to see the road clearly without creating excessive glare. They are designed to shine lower and broader on the road surface, allowing drivers to avoid obstacles while reducing the likelihood of reflecting light back towards their own eyes.

Daytime running lights are typically not bright enough to improve visibility in poor conditions like fog since they are designed for daylight use and do not illuminate the road as effectively as low beams. Parking lights are even less effective in fog as they are intended for stationary vehicles and do not provide adequate illumination for safe driving. Therefore, utilizing low beam headlights is the most effective and safe choice when navigating through fog.
