California Oversize/Overweight Permit (6-CA-a)

Information current as of 2021
In California, a developer may need to obtain a Oversize/Overweight Permit from the California Department of Transportation (Caltrans) to move a vehicle or load, that exceeds statutory limits, on a state highway or street. Caltrans has discretionary authority under Cal. Veh. Code § 35780 to issue Oversize/Overweight Permits for the movement of vehicles on state highways and streets with loads exceeding the statutory limitations on size, weight, and loading. Caltrans establishes the administrative process, standards, and conditions for issuing Transportation Permits in Caltrans Transportation Permits Manual (TPM).
