What should you do when driving in fog?

When driving in fog, using low beam headlights is the recommended practice. Low beam headlights are designed to provide adequate illumination of the road while minimizing the amount of light that is reflected back by the fog, which can create glare and hinder visibility. They help to illuminate the road directly in front of your vehicle, allowing you to see clearly without creating excessive blinding reflections that can occur with high beams.

In contrast, high beam headlights can worsen visibility in foggy conditions. The light from high beams is directed forward and can be scattered by the moisture in the fog, creating a white wall of light that makes it more difficult to see the road. Likewise, driving with hazard lights on could confuse other drivers and is not intended for use while driving in poor visibility conditions. Increasing your speed in fog is dangerous and ill-advised, as reduced visibility requires a more cautious approach. Using low beam headlights allows for safer navigation through fog by improving your chance of spotting road markings and obstacles while helping other drivers see you.
