What should you do when driving in fog?

When driving in fog, using low beam headlights and reducing speed is essential for safety. Low beam headlights are designed to provide better visibility in foggy conditions as they illuminate the area closer to the road without causing significant glare. High beams can reflect off the fog, rain, or snow, creating a blinding effect that makes it even harder to see.

Reducing speed is equally important because fog can drastically decrease visibility, making it difficult to gauge distances and react to obstacles or other vehicles. Traveling at a slower speed allows for greater reaction time if unexpected situations arise, such as a sudden stop from the vehicle ahead.

Turning off headlights completely is not advisable, as it leaves you without visibility and makes it harder for other drivers to see you. Speeding up to stay ahead in fog is also dangerous, as it increases the risk of losing control or not spotting hazards in time. Thus, choosing to use low beam headlights while reducing your speed is the most effective way to navigate fog safely.
