California’s “Commercial Vehicle Enforcement Facilities” are commonly called weigh stations or truck scales. These facilities are operated by the California Highway Patrol (CHP), not by Caltrans. However, Caltrans receives many inquiries about weigh stations. This page is designed to answer some of those questions.
California Vehicle Code Section 2813 outlines who must stop at weigh stations and inspection stations:
- Every driver of a commercial vehicle shall stop and submit the vehicle to an inspection of the size, weight, equipment, and smoke emissions of the vehicle at any location where members of the California Highway Patrol are conducting tests and inspections of commercial vehicles and when signs are displayed requiring the stop. Every driver who fails or refuses to stop and submit the vehicle to an inspection when signs are displayed requiring that stop is guilty of a misdemeanor.
California Vehicle Code Section 260 defines “commercial vehicle”
- (a) A “commercial vehicle” is a motor vehicle of a type required to be registered under this code used or maintained for the transportation of persons for hire, compensation, or profit or designed, used, or maintained primarily for the transportation of property.
(b) Passenger vehicles which are not used for the transportation of persons for hire, compensation, or profit and house cars are not commercial vehicles. …
(c) Any van pool vehicle is not a commercial vehicle.
