What must you do when driving in foggy conditions?

In foggy conditions, using low beam headlights is essential. This is because low beam headlights provide a more effective illumination that reduces the amount of light that reflects off the fog or precipitation back at the driver. High beam headlights can actually make visibility worse in foggy conditions by shining light into the fog, which reflects the rays back and creates a glare, making it harder to see ahead.

Proper use of low beam headlights helps you see the road clearly and allows other drivers to see you, thus enhancing safety while driving in low visibility situations. It’s also important to adjust your speed appropriately based on visibility, but low beam headlights are a crucial first step in navigating fog safely.
