What should you avoid doing when driving in fog?

Using high beam headlights in foggy conditions is not advisable because the light can reflect off the fog droplets and create a glare that reduces your visibility. Instead, it is recommended to use low beam headlights as they provide better illumination of the road directly in front of you and help other drivers see you without causing glare. In fog, visibility can be significantly decreased, and proper headlight usage is crucial for safe driving.

While using high beams may seem like a way to enhance visibility, it can actually worsen the situation by causing the light to scatter and create a wall of brightness that obstructs your ability to see through the fog. Low beams are much more effective for navigating in foggy conditions, allowing you to see and be seen more clearly.
