What should you do when driving in foggy conditions?

Using low beam headlights in foggy conditions is the best practice because high beams can actually make visibility worse. The light from high beams reflects off the fog, rain, or snow, creating a glare that can obscure your vision and make it harder to see. Low beam headlights provide a more adequate amount of light that is directed towards the road and helps illuminate the area immediately in front of your vehicle without causing excessive glare.

Driving at the speed limit in fog is not advisable, as visibility can be severely limited. The speed limit is set for ideal driving conditions, and fog requires a slower speed for safety. Additionally, pulling over and waiting for the fog to clear might not always be feasible depending on the situation, as it can create hazards for other drivers. Therefore, using low beam headlights provides the most effective means of improving visibility and ensuring a safe driving experience in foggy conditions.
