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

When driving in fog, using low beam headlights is crucial for visibility and safety. Low beams are designed to illuminate the road directly in front of you without causing excessive glare, which can reflect off the fog and hinder your ability to see. This lighting allows you to see more clearly while also not blinding other drivers or creating a hazardous driving environment.

Fog lights can also be helpful, but they are specifically designed to illuminate the area directly in front of the vehicle and are often used in combination with low beams for enhanced visibility. High beams, on the other hand, increase glare in thick fog, rain, or snow because they can reflect off water droplets in the air, making it even harder to see. Turning signals are intended for indicating turns or lane changes and do not aid in visibility in foggy conditions. Thus, utilizing low beams is the safest and most effective approach when navigating through fog.
