What should I do when driving a motor vehicle in low visibility weather such as heavy fog or extraordinarily heavy fog?

When driving a motor vehicle in foggy or extremely foggy weather with low visibility, you should drive to the roadside safety zone or parking lot first, and then drive on the road after the visibility improves. The following is extended information:

1. Driving requirements in foggy days: According to the driving requirements, when the visibility is 200 to 500 meters, the speed of driving low beam, width indicator and taillight shall not exceed 80; Visibility is between 100 and 200m. Except driving low beam, width indicator and tail light, the vehicle speed shall not exceed 60m. Maintain at least 100 meter. When the visibility is between 50 ~ 100 meters, except for turning on the above lights, the speed shall not exceed 40 meters, and the distance between vehicles shall be kept at least 50 meters. 2. Lighting regulations: Turn on front and rear fog lights, tail lights, width lights and low beam lights to improve visibility. This will not only let you see the situation in front, but also let your car be seen by the drivers coming from behind. If the high beam is used, the light will be reflected by the fog, thus forming a white blind spot in front of the driver, which is very dangerous.
