What does a driver need to do when driving in fog?

When driving in fog, using low beam headlights and reducing speed is essential for safety. Low beam headlights are designed to illuminate the road directly in front of the vehicle without causing glare that could reflect off the fog and impair visibility even further. High beam headlights can create a white wall effect, making it harder for the driver to see.

Reducing speed is equally important in foggy conditions because visibility is significantly limited, and stopping distances are increased. Slowing down allows drivers to react more effectively to any sudden obstacles or changes in the road conditions that may not be visible until they are very close.

In summary, using low beam headlights helps maintain clear visibility without increasing glare, and reducing speed allows for safer navigation through foggy conditions, making this approach the most appropriate and effective for safe driving in such weather.
