Using low beam headlights in foggy conditions is effective because they help illuminate the road without causing excessive glare. In fog, high beam headlights can reflect off the water droplets in the air, resulting in a blinding effect for the driver and reducing visibility. Low beams, on the other hand, provide a more controlled and effective light source that cuts through the fog and allows you to see the road and any potential obstacles more clearly.

Fog lights, while they can be useful in very dense fog conditions, are designed specifically to illuminate the road immediately in front of the vehicle. However, they are most effective when used in conjunction with low beam headlights, rather than on their own. Not using any headlights at all would significantly impair visibility, leading to a greater risk of accidents. Therefore, low beam headlights are the best choice for safely navigating through fog.
