What is an important consideration when driving in fog?

When driving in fog, using low beam headlights is crucial because they help improve visibility without causing glare. High beam headlights can reflect off the fog, rain, or snow, creating a blinding effect that can significantly hinder your ability to see other vehicles or obstacles. Low beams, however, provide sufficient illumination for the road ahead while minimizing reflection off the fog, allowing for a safer driving experience.

Driving at maximum speed is never advisable in foggy conditions due to the reduced visibility that can obscure hazards and limit your reaction time. Turning off all lights is also not safe, as it leaves you completely invisible to other drivers, significantly increasing the risk of an accident. Thus, using low beam headlights is the most effective strategy to navigate through fog safely.
