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

Using low beam headlights in foggy conditions is essential for maintaining visibility while avoiding the reflection that can occur with high beams. High beam headlights cast light further ahead, but in fog, this light can bounce off the moisture in the air, creating a glare that significantly reduces visibility. Low beams, on the other hand, are aimed downward and illuminate the road immediately in front of the vehicle, which helps drivers see without causing excessive reflection that could impair their own sight or that of other drivers.

Fog lights can provide additional illumination in very thick fog, but they are typically used in conjunction with low beam headlights rather than exclusively. Driving without headlights in fog is unsafe as it can lead to accidents due to lack of visibility. Therefore, using low beam headlights is the safest and most effective option for navigating through foggy conditions.
