What is the best advice for drivers when heavy fog occurs?

When heavy fog occurs, the best course of action is to avoid driving until the fog has lifted. Fog significantly reduces visibility, which can make it difficult to see the road, other vehicles, and obstacles. Drivers may struggle to judge distances and speeds, increasing the risk of accidents.

Delaying travel allows conditions to improve, ensuring a safer driving experience when visibility is restored. This recommendation is supported by the fact that fog can change quickly, and what may be acceptable visibility at one moment can deteriorate further, putting drivers in precarious situations.

While other methods, such as using low beams or maintaining a safe distance from other vehicles, can be important in foggy conditions, they do not address the underlying issue of reduced visibility. Prioritizing safety by postponing travel is often the wisest decision in heavy fog scenarios.
