When driving in fog, which headlight setting is recommended for better visibility?

When driving in fog, the recommended headlight setting is low beam. This is because low beam headlights produce less glare and are positioned in such a way that they illuminate the road immediately in front of the vehicle without reflecting excessively off the fog, rain, or snow. High beam headlights can create a blinding effect when their light reflects off the fog, making visibility worse by creating a wall of light that obscures the road ahead.

Using no headlights is unsafe as it virtually eliminates visibility for both the driver and other road users, dramatically increasing the risk of accidents. Fog lights are specifically designed to distribute a wide, low beam of light that can penetrate fog better than regular headlights; however, they are typically used in combination with low beam headlights rather than as standalone options. Therefore, using low beam headlights is the most effective choice for enhancing visibility in foggy conditions.
