How does fog typically affect driving conditions?

Fog significantly reduces visibility due to the moisture present in the air, which scatters light and creates a dense, opaque barrier. This can make it difficult for drivers to see other vehicles, road signs, and any potential hazards on the road. As a result, driving in foggy conditions requires increased caution, slower speeds, and often the use of low-beam headlights, which are designed to illuminate the road without creating glare. Adapting to these reduced visibility conditions is crucial for safely navigating through fog.
