What should you do if you encounter fog while driving?

When driving in fog, it is essential to use low-beam headlights and reduce your speed for several important reasons. Low-beam headlights are optimal in foggy conditions because they illuminate the road immediately in front of the vehicle without causing glare that can reflect off the fog and into your eyes. This helps maintain visibility without exacerbating the hazardous conditions.

Reducing your speed is crucial during fog because it allows you to respond more effectively to sudden changes in visibility and road conditions. Fog can obscure landmarks and road signs, so driving at a slower pace enhances reaction time and provides greater control of the vehicle. This combination of using low-beam headlights and reducing speed aims to improve overall safety, both for yourself and for other drivers on the road.

Stopping until the fog clears can be a safe option, but it is not always practical, especially on busy roads. Using high-beam headlights can actually worsen visibility in fog, and driving without headlights is extremely dangerous and illegal, as it severely limits visibility for both you and other vehicles.
