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

[ParkerFitz]

The main impact of foggy weather on safe driving is reduced visibility and unclear sight. In light fog areas, it is necessary to appropriately reduce driving speed and increase the distance between vehicles. The following are specific requirements for driving in foggy conditions: When visibility is between 200 meters and 500 meters: You must turn on the anti-glare low beam, width marker lights, and tail lights, with speed not exceeding 80 km/h, and maintain a distance of more than 150 meters between vehicles. When visibility is between 100 meters and 200 meters: You must turn on the fog lights, anti-glare low beam, width marker lights, and tail lights, with speed not exceeding 60 km/h, and maintain a distance of more than 100 meters between vehicles. When visibility is between 50 meters and 100 meters: In addition to turning on the above lights, speed should not exceed 40 km/h, and maintain a distance of more than 50 meters between vehicles. When visibility is below 50 meters, it is considered extremely dense fog, and public security authorities may implement traffic management measures such as partial or full closure of highways according to regulations.
