What are the main impacts of foggy weather on safe driving?

The main impact of foggy weather on safe driving is low visibility and unclear vision. In light fog areas, it is necessary to appropriately reduce driving speed and increase the distance between vehicles. When driving in foggy weather, the following specific requirements should be noted: When visibility is between 200 meters and 500 meters: Anti-glare low beam lights, width lights, and tail lights must be turned on. The speed must not exceed 80 kilometers per hour, and the distance between vehicles should be maintained at more than 150 meters. When visibility is between 100 meters and 200 meters: Fog lights, anti-glare low beam lights, width lights, and tail lights must be turned on. The speed must not exceed 60 kilometers per hour, and the distance between vehicles should be maintained at more than 100 meters. When visibility is between 50 meters and 100 meters: In addition to turning on the above lights, the speed must not exceed 40 kilometers per hour, and the distance between vehicles should be maintained at more than 50 meters. When visibility is below 50 meters, it is considered extremely dense fog, and the public security authorities may implement traffic management measures to close sections or entire stretches of highways according to regulations.
The biggest risk when driving in fog is low visibility. You simply can't see the vehicles ahead or road signs clearly, and misjudging the safe distance may lead to rear-end collisions. I often drive on highways, and when heavy fog occurs, visibility shrinks to just tens of meters—a momentary lapse in attention could result in a crash. Another issue is psychological tension, which can lead to sudden acceleration or braking, increasing the likelihood of accidents. It's advisable to reduce speed in foggy conditions, turn on front and rear fog lights (avoid using high beams), and maintain double the usual following distance. If the fog becomes too dense, find a safe place to pull over and wait for conditions to improve. Regularly checking your vehicle's lights is also crucial to ensure they properly illuminate the road in fog.
