Legal basis:

Article 39 of the Road Traffic Safety Law of the People's Republic of China stipulates that traffic can be restricted: "The traffic management department of the public security organ may take measures such as diverting, restricting traffic and prohibiting traffic for motor vehicles, non-motor vehicles and pedestrians according to the specific conditions of roads and traffic flows. In case of large-scale mass activities and large-scale construction, etc. If it is necessary to take traffic restriction measures or make decisions directly related to public road traffic activities, it should be announced to the public in advance.
