Trucks are limited to a few times a day at most.

Legal analysis: there is no upper limit on the number of times, but the punishment is only once. Tail number restriction system is a kind of traffic system born to alleviate the urban traffic pressure. Driving into the restricted area on the restricted day was photographed by the electronic eye many times on that day, and it was only punished once on that day, with a fine of 100 yuan. He was caught by the police that day and fined 100 yuan. If he meets the police again that day, the punishment certificate before birth will not be repeated.

Legal basis: Road Traffic Safety Law of the People's Republic of China.

Article 39 The traffic administrative department of the public security organ may, according to the specific conditions of roads and traffic flows, take measures such as diverting, restricting traffic and prohibiting traffic for motor vehicles, non-motor vehicles and pedestrians. In case of large-scale mass activities and large-scale construction, etc. If it is necessary to take measures to restrict traffic or make decisions directly related to public road traffic activities, it shall be announced to the public in advance.

Article 90 A motor vehicle driver who violates the provisions of laws and regulations on road traffic safety shall be given a warning or fined from 20 yuan to 200 yuan. If there are other provisions in this law, it shall be punished in accordance with its provisions.
