What does vehicle restriction mean?

[Rafael]

Vehicle restriction is a traffic control policy that prohibits vehicles with certain license plate endings from driving on specific days. The purpose of vehicle restriction is to alleviate traffic congestion caused by the rapid increase in vehicles and to reduce urban motor vehicle exhaust emissions, thereby keeping the urban air pollution index within a reasonable range. The following vehicles are exempt from restrictions: 1. Special vehicles: police cars, fire trucks, ambulances, and engineering rescue vehicles. 2. Diplomatic vehicles: vehicles with diplomatic license plates and those approved for temporary entry. 3. Official vehicles: administrative law enforcement vehicles and specialized towing vehicles with unified markings performing official duties. 4. Special-purpose vehicles: sanitation, landscaping, road maintenance vehicles, and funeral hearses. 5. Approved vehicles: company shuttle buses and school buses approved by the municipal public traffic management department.
