What precautions should you take when driving in fog?

When driving in fog, reducing speed and using low-beam headlights is crucial for safety. Fog can significantly diminish visibility, making it difficult to see other vehicles, traffic signals, and road signs. By reducing speed, drivers have more time to react to unexpected obstacles or changes in traffic conditions.

Using low-beam headlights is important because high-beam headlights can reflect off the moisture in the fog, creating glare that further impairs visibility. Low-beam headlights are designed to illuminate the road directly in front of the vehicle while minimizing reflections and glare, making them the safer choice in foggy conditions.

In contrast, driving without headlights can lead to total darkness on the road, increasing the likelihood of accidents. Following another vehicle closely is also unsafe; it reduces the ability to respond to sudden stops or changes in motion, and the limited visibility in fog necessitates a greater following distance for safety.
