When driving in fog, using low beam headlights and reducing speed is recommended because it helps improve visibility and reduces the risk of accidents. Low beam headlights are specifically designed to illuminate the road directly in front of your vehicle without causing excessive glare that can reflect off the fog, rain, or snow, which can impair visibility even further. Reducing speed is essential in foggy conditions due to the limited visibility, allowing for more time to react to potential hazards or obstacles on the road.

Driving faster or using high beam headlights can be counterproductive because high beams can create a wall of light that reflects off the fog, reducing visibility. Additionally, maintaining adequate speed is crucial, as visibility may change rapidly in foggy conditions, making it difficult to stop in time if an unexpected situation arises. Therefore, using low beam headlights and reducing speed together create a safer driving environment in fog.
