If you are driving and encounter fog, what should you do?

When encountering fog while driving, reducing your speed and using low beams is the safest and most effective approach. Fog reduces visibility significantly, and driving at a slower speed allows you more time to react to any potential hazards that might be obscured. Additionally, low beam headlights are designed to provide better illumination in foggy conditions without causing glare, which is important because high beam headlights reflect off the fog and can actually worsen visibility.

Using high beams can create a wall of light that bounces back at the driver, making it harder to see the road ahead. Driving with your hazards on can signal to other drivers that you are experiencing difficulty, but it is not a substitute for proper headlights or speed management. While pulling over and waiting until conditions improve might seem like a good option, it is not always practical or safe, especially if you are on a busy road. Therefore, reducing speed and using low beams is the answer that best enhances safety in foggy conditions.
