Weigh Stations laws in California
California Vehicle Code section 2813 requires commercial-vehicle drivers to stop where CHP conducts inspections and signs require a stop. Caltrans explains that commercial vehicles include vehicles used to transport people for compensation or primarily to transport property, while personal passenger vehicles, housecars and vanpool vehicles are excluded. A statutory pickup has a manufacturer GVWR below 11,500 pounds, unladen weight below 8,001 pounds and an open box bed no longer than 9 feet; utility bodies do not qualify. Caltrans reports that California scales post “No Pickups” signs, so qualifying pickups need not stop under those signs. Trucks outside that definition, including utility-body or flatbed conversions, must stop when required. Rental moving trucks are included; a rental pickup depends on its configuration. Camper-shell cases can require individual CHP confirmation.
