Should you ever drive with your high beams on in foggy conditions?

Driving with high beams on in foggy conditions is not advisable because the light from the high beams can reflect off the fog, causing a glare that actually reduces your visibility. Fog consists of tiny water droplets suspended in the air, and when high beams are used, the intense light strikes these droplets and scatters, creating a bright wall of light that obscures the driver's view of the road and any potential hazards.

In contrast, using low beams is recommended in foggy conditions. Low beams provide sufficient illumination without the problematic glare caused by high beams. They allow drivers to see the road more clearly and help maintain better safety when navigating through fog. This principle also applies to other adverse weather conditions such as rain and snow, where visibility is already compromised.
