California Motor Carrier Permit: Requirements, Fees, and Filing Steps

A California Motor Carrier Permit is the state credential that lets a business operate a commercial motor vehicle on California highways, and the California DMV issues it only after you’ve obtained a USDOT number, a CHP-assigned carrier identification number, and filed proof of the required insurance.¹ Once issued, the permit lasts 12 months and carries ongoing inspection, reporting, and insurance obligations that keep it active.

Who Needs One

California Vehicle Code Section 34620 bars any motor carrier of property from operating a commercial motor vehicle on a public highway without a valid MCP and a registered carrier identification number.² That covers for-hire carriers hauling goods for compensation and private carriers moving their own property in commercial vehicles.

Section 34601 defines a commercial motor vehicle as any motortruck of two or more axles with a gross vehicle weight rating over 10,000 pounds, plus any vehicle used to transport property for compensation regardless of size. Combinations that cross that weight threshold when a trailer is attached count too. Vehicles transporting placarded hazardous materials, or anything requiring a hazmat license or hazardous waste transporter registration, generally need the permit even if the truck itself is under 10,000 pounds.³ Drivers operating vehicles that require a commercial driver’s license also need the permit.¹

Narrow Exemptions

Section 34622 exempts vehicles carrying historical or special-interest plates under Vehicle Code Sections 5004 and 5011, vehicles exempt from registration fees, and household movers operating under a household mover permit issued through the Business and Professions Code.⁴ Section 34601 also excludes pickups not towing regulated loads, two-axle rental trucks under 26,001 pounds used for non-commercial purposes, and privately owned vehicles under 26,001 pounds that are never used commercially.³ If your operation sits near one of these edges, the safer move is to apply; the penalty for operating without a permit dwarfs the filing cost.

How to Apply

Three agencies touch the application, and the order matters.

Step 1: Get a USDOT Number

Start with the Federal Motor Carrier Safety Administration. State law requires carriers to have a USDOT number before the CHP will assign a carrier identification number.⁵ You can apply through FMCSA’s Unified Registration System online, which issues USDOT numbers instantly.⁶

Step 2: Get a CA Number From the CHP

With your USDOT number, apply to the California Highway Patrol for a Carrier Identification Number, known as the CA number.⁷ This number stays with your business as the reference for all state safety and compliance filings, and the CHP uses it to track your fleet’s inspection history.

Step 3: File Form MC 706 M With the DMV

Once both numbers are in hand, complete the Application for Motor Carrier Permit (form MC 706 M), available as a PDF on the DMV website. The application asks for your business’s legal name, physical address, and federal Employer Identification Number or Social Security Number. If your fleet includes CDL drivers, you’ll likely already have an EIN, because the IRS requires one on Form 2290 for the Heavy Highway Vehicle Use Tax.⁸

Include proof of liability and property damage insurance at the levels required for your vehicle class, along with Workers’ Compensation coverage if you have employees.¹ Carriers enrolled in the Employer Pull Notice program should add their five-character Requester Code so driver monitoring records tie to the application.⁹

Mail the completed application and fees to:

Department of Motor Vehicles
Registration Operations Division
PO Box 932370 – MS H875
Sacramento, CA 94232-3700

Existing permit holders can renew online, which the DMV says is faster. The permit will not issue until every requirement is met.

Insurance You Must File

The DMV won’t issue or renew an MCP without a Certificate of Insurance on file. Minimum liability amounts track the federal baselines FMCSA sets for most carrier types:¹⁰

General freight at 10,001 pounds GVWR and above: $750,000 combined single limit for bodily injury and property damage
Oil and certain hazardous materials: $1,000,000
Explosives, poison gas, or radioactive materials: $5,000,000
Household goods carriers at 10,001 pounds and above: $750,000 plus $5,000 cargo insurance

Carriers with employees must also carry Workers’ Compensation. Any lapse in required coverage can trigger permit suspension, so most carriers set up automatic renewal and ask the insurer to file proof directly with the DMV.

Permit Fees

MCP fees depend on two things: whether you run a for-hire or private operation, and the number of power units in your fleet.¹ The current schedule is published in the DMV’s MCP Handbook. After a suspension ends, a $150 reinstatement fee applies on top of normal costs.¹¹

Vehicle Marking

Every vehicle covered by the permit has to display the carrier identification number on both sides. Section 34507.5 requires markings that contrast sharply with the vehicle’s background color and stay legible from 50 feet away in daylight.⁵ For combination vehicles, the number must appear on at least one motor vehicle in the combination. Enforcement officers spot missing or faded markings easily, and a citation can issue on that basis alone.

Keeping the Permit Active

An MCP is valid for 12 months.¹² The DMV sends renewal notices, but the duty to renew on time belongs to the carrier whether a notice arrives or not. Operating with an expired permit can bring fines, impoundment, or an out-of-service order at a roadside stop.

90-Day Inspections

Vehicle Code Section 34505.5 requires every regulated commercial vehicle to be inspected at least every 90 days as part of the carrier’s maintenance program. Inspections must cover brake adjustment, brake system components and leaks, steering and suspension, tires and wheels, and vehicle connecting devices. A vehicle that fails inspection cannot return to public roads until defects are corrected. Records must be kept at the carrier’s terminal for at least two years and produced for the CHP on request.¹³

BIT Terminal Audits

The CHP’s Basic Inspection of Terminals (BIT) program audits carrier facilities on a recurring basis. CHP Motor Carrier Specialists review vehicles, maintenance records, driver files, and hazmat handling where applicable, giving each category a satisfactory or unsatisfactory rating. An unsatisfactory finding triggers a follow-up reinspection within 120 days, and repeated noncompliance can lead to permit suspension.¹⁴

Reporting Changes

Report changes to your business name, physical address, fleet size, or other registration details within 15 days. Keep your USDOT information current, updating it at least once every two calendar years and within 15 days of any change.⁵ Missed updates can bring administrative penalties or suspension.

Penalties for Operating Without a Permit

A violation of this division of the Vehicle Code is a misdemeanor punishable by a fine of up to $2,500, up to three months in county jail, or both. Operating after suspension carries the same penalties, and each day of continued operation counts as a separate offense.¹⁵ Enforcement officers can also place a vehicle out of service on the spot, which means the truck sits until compliance is restored. Reinstating a suspended permit requires correcting the underlying violation, paying the $150 reinstatement fee, and in some cases filing a new application.¹¹

What the MCP Doesn’t Cover

A California MCP authorizes intrastate operations only. Crossing state lines adds a separate federal layer. For-hire carriers transporting federally regulated commodities in interstate commerce need operating authority (an MC number) from FMCSA on top of their USDOT number; private carriers and for-hire carriers hauling only exempt commodities do not.¹⁶ Interstate carriers also owe annual Unified Carrier Registration fees based on fleet size, due January 1 each year with a pre-registration window opening October 1 of the prior year.¹⁷ Separate federal rules on electronic logging devices, the Drug and Alcohol Clearinghouse, and annual vehicle inspections under 49 CFR Part 396 apply alongside California’s 90-day cycle; the state inspections satisfy the federal annual requirement by exceeding its frequency, but inspectors still must meet federal credentialing standards.¹⁸
