When driving on an expressway in adverse weather with visibility less than 100 meters, what is the minimum distance to maintain from the vehicle ahead in the same lane?

ANSWER · A

According to the "Road Traffic Safety Law of the People's Republic of China and its implementing regulations", on expressways in low-visibility conditions such as fog, rain, snow, sand, or hail: (1) When visibility is less than 200 meters, turn on fog lights, low beams, sidelights, and front and rear position lights, keep speed under 60 km/h, and stay more than 100 meters behind the vehicle ahead in the same lane; (2) When visibility is less than 100 meters, also turn on hazard flashers, keep speed under 40 km/h, and stay more than 50 meters behind; (3) When visibility is less than 50 meters, with the same lights on, keep speed under 20 km/h and exit the expressway from the nearest exit as soon as possible. The expressway management department should display speed-limit and following-distance information on screens when these conditions apply.
