What should a driver do when approaching a foggy area?

When approaching a foggy area, it’s essential to use low-beam headlights and reduce speed for several reasons. Low-beam headlights are designed to illuminate the road immediately in front of the vehicle without reflecting off the fog, rain, or snow, which can cause glare and make visibility even worse. Using high-beam headlights, on the other hand, can reflect off the fog particles, creating a white wall effect that severely limits the driver’s ability to see.

Reducing speed is crucial in foggy conditions as visibility is often significantly impaired. By slowing down, a driver gives themselves more time to react to any hazards or changes in the road conditions ahead. Maintaining the same speed in fog can lead to dangerous situations, as the driver may not be able to see obstacles, other vehicles, or road signs clearly.

Accelerating in fog might seem like it would help the driver get out of the fog faster, but this can lead to a lack of control and increased risk of an accident, as reduced visibility does not afford the driver adequate time to react. Thus, using low-beam headlights and reducing speed are the safest and most effective strategies for navigating through foggy conditions.
