Driving in fog can significantly reduce visibility and create hazardous conditions. The best practice in such situations is to keep your headlights on low beam and increase your following distance.

Using low beam headlights improves visibility by reducing the amount of light that reflects off the fog, which can happen with high beam headlights. High beams can cause glare, making it even more difficult to see. By maintaining a low beam setting, drivers can see the road and any potential obstacles more clearly.

Increasing your following distance is crucial because visibility is compromised, and your stopping distance will be longer in foggy conditions. A greater following distance provides additional time to react to sudden stops or changes in traffic, improving safety for both you and the vehicles around you. This approach promotes a cautious mindset and enhances overall road safety when facing challenging weather conditions like fog.
