[Cynthia]

Highways are free for 7 days during the National Day holiday (October 1 to October 7). Here are the relevant details: 1. Regulations: According to the "Implementation Plan for Exempting Toll Fees for Small Passenger Vehicles on Major Holidays," the toll-free period applies to four national statutory holidays: Spring Festival, Qingming Festival, Labor Day, and National Day, as well as the consecutive holidays determined by the State Council. 2. Free period: The toll-free period starts at 00:00 on the first day of the holiday and ends at 24:00 on the last day of the holiday (for ordinary roads, the time is determined by when the vehicle passes the toll booth; for highways, the time is determined by when the vehicle exits the toll lane).
