Legal analysis: not free. All trucks have to pay for taking the expressway on holidays.

During the four legal holidays of Spring Festival, Tomb-Sweeping Day, May Day and National Day, only passenger cars with less than seven seats (including seven seats) can take the expressway for free, and all trucks and buses with more than eight seats (including eight seats) still have to collect tolls.

Legal Basis: Implementation Plan for Exempting Passenger Cars from Toll on Major Holidays I. Scope of Implementation (I) The time range of free passage is the four national statutory holidays, such as Spring Festival, Tomb-Sweeping Day, Labor Day and National Day, and the above-mentioned statutory holidays determined by the documents of the General Office of the State Council in that year. The free time period starts at 00: 00 on the first day of the holiday and ends at 24: 00 on the last day of the holiday (the time when the vehicle passes through the toll lane of the toll station shall prevail for ordinary highways, and the time when the vehicle leaves the exit toll lane for expressways). (2) The range of vehicles that pass free of charge is passenger vehicles with less than 7 seats (including 7 seats) driving on toll roads, including motorcycles that are allowed to drive on ordinary toll roads. (3) Toll roads that pass freely refer to toll roads (including toll bridges and tunnels) that conform to the provisions of the Highway Law of People's Republic of China (PRC) and the Regulations on the Administration of Toll Roads. Whether airport expressways around the country are free or not is decided by the people's governments of all provinces (autonomous regions and municipalities).
