State guide

Start and run a trucking company in California

California asks more of a new trucking company than any other state. For-hire property carriers need a Motor Carrier Permit at any vehicle weight, a CA# from the CHP, and a USDOT number even for in-state work. This hub walks through each requirement, with every fact tied to an official source.

The short answer

State authority
Required

Weight trigger 10,001 lb GVWR, among others

State filing fee
From $250

Issued by California Department of Motor Vehicles (DMV), Motor Carrier Services; safety regulation by the California Highway Patrol (CHP)

Credential Motor Carrier Permit (MCP)

What these terms cover

State filing fee: Total for a for-hire intrastate carrier with a fleet of 1 power unit: $120 base fees (Safety Fee plus Uniform Business License Tax) plus a $130 Carrier Inspection Fee (CIF). A private carrier with 1 power unit pays $165 ($35 base plus $130 CIF). Fees scale by fleet size per the MCP Handbook fee chart; the CIF is never prorated. Interstate carriers prorate base fees by California mileage (MC 706 M Section 13) but pay the full CIF.

How California differs from other states

Most states hang their trucking rules on a weight line. California starts lower: haul property for compensation and the Motor Carrier Permit applies at any weight, motorcycle couriers included. The state also wires programs together. You cannot get a CA# without a USDOT number, you cannot get the permit without the CA#, and a heavy truck cannot renew its registration while it owes the CARB emissions program a test or a fee. The sourced fields on the pages below carry each trigger and figure.

Which agency handles what

Five agencies share the load. The DMV issues the Motor Carrier Permit and runs apportioned registration. The CHP assigns the CA# and inspects carrier terminals. The CDTFA licenses carriers under the fuel tax agreement. Caltrans issues oversize and overweight permits for the state highway system. CARB runs the Clean Truck Check emissions program. Each page in this hub names the agency, the process, and the sourced fee fields for its topic.

Frequently asked questions

Do I need more than my federal paperwork to haul freight in California?

Yes. A for-hire property carrier operating inside California needs the state Motor Carrier Permit from the DMV plus a CA# from the CHP, on top of any federal registration. The intrastate authority page breaks down the agency, the application, and the sourced fee chart.

Which California agencies will I deal with as a new carrier?

The DMV for the Motor Carrier Permit and apportioned plates, the CHP for the CA# and terminal inspections, the CDTFA for the fuel tax license, Caltrans for oversize permits, and CARB for the Clean Truck Check emissions program.

Does California regulate trucks registered in other states?

Yes. The Clean Truck Check emissions program covers heavy vehicles that operate on California roads regardless of where they are registered, with reporting, an annual compliance fee, and periodic testing. The sourced program fields carry the weight rating line and the current fee.
