What is a common hazard when driving in foggy conditions?

Driving in foggy conditions presents a significant challenge for visibility, which directly correlates to an increased risk of collisions. Fog can reduce visibility to a mere few feet in extreme cases, making it difficult for drivers to see other vehicles, pedestrians, and road signs. The limited ability to see ahead can lead to slower reaction times and the potential for dangerous situations, such as rear-end accidents or failing to yield at intersections. Therefore, heightened caution should be exercised in fog, and reducing speed and increasing following distances becomes critical to mitigate these risks. Recognizing that fog creates a persistent hazard necessitates adjustments in driving behavior to maintain safety on the road.
