When driving in foggy conditions, what lights should you use?

Using low beam headlights in foggy conditions is essential for improving visibility without causing glare that can hinder your ability to see. High beam headlights tend to reflect off the water droplets in the fog, worsening visibility and creating a blinding effect for both the driver and oncoming vehicles. Low beams are designed to cast light down onto the road, which helps illuminate the path ahead without creating excessive reflection.

Parking lights and hazard lights are not adequate for driving in fog as they do not provide sufficient illumination for the road. Parking lights are primarily meant for stationary vehicles, while hazard lights indicate a vehicle is stopped or experiencing an issue, and they do not help in enhancing visibility in poor weather conditions. Therefore, using low beam headlights is the safest and most effective choice when navigating through fog.
