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

When driving in fog, using low beam headlights is essential for improving visibility. High beam headlights can reflect off the fog and create glare, making it even more difficult to see. This is because the light from high beams travels farther, but when it hits the water droplets in fog, it bounces back toward the driver, causing a blinding effect.

Low beam headlights, on the other hand, provide a more focused beam that illuminates the road directly in front of you without scattering light back into your eyes. They are designed to cut through fog, rain, or snow more effectively, allowing for better visibility of both the road and any obstacles.

Fog lights can also be used in conjunction with low beam headlights, as they are specifically designed to illuminate the area immediately in front of the vehicle and reduce the effects of fog glare. However, they should not be used alone if visibility is severely reduced; low beams should accompany their use for optimal safety.
