When driving in fog conditions, it is essential to reduce speed and use low beam headlights. Fog significantly reduces visibility, making it difficult to see other vehicles and the road ahead. By lowering your speed, you give yourself more time to react to unexpected obstacles or changes in traffic. This cautious approach helps in maintaining control over the vehicle and ensures safer navigation through limited visibility.

Using low beam headlights is crucial in foggy conditions because they provide a wider, shorter beam of light that helps illuminate the road directly in front of the vehicle without reflecting off the fog, rain, or snow. High beam headlights, on the other hand, tend to reflect off the moisture in the fog, creating a glare that can further impair visibility, making it harder to see. Maintaining normal speed and staying in the center lane may lead to a false sense of security, while turning off all lights would completely eliminate necessary visibility, both of which are unsafe practices when driving in fog.
