When driving in fog, what is the recommended practice for using headlights?

Using low beams in fog is the recommended practice because they provide better visibility without creating excessive glare. In foggy conditions, high beams can cause the light to reflect off the fog droplets, creating a blinding effect that hinders rather than helps visibility. Low beams are designed to project light downwards onto the road, minimizing reflection and helping the driver see the road and other vehicles more clearly.

Additionally, relying on turn signals is important for indicating your intentions to other drivers, but it does not directly aid in visibility through fog. Turning off all lights would be unsafe, as it would make the vehicle less visible to others and leave the driver without sufficient illumination to navigate the road. Therefore, using low beams is the safest and most effective approach when driving in foggy conditions.
