Dump Truck Insurance in California: MCP, CA Number and Coverage

Short answer: if you haul dirt, rock, sand or debris for pay in California, you need a USDOT number, a CA number from the CHP and a Motor Carrier Permit (MCP) from the DMV. Your insurer files proof of coverage with the DMV on an MC 65 M. For property other than hazmat in a truck rated 10,001 lbs GVWR or more, the DMV minimum is $750,000 combined single limit. Most contractors will also ask for general liability and specific wording on your certificate.
Dump truck owners usually find out what they're missing at the worst time: the job is lined up, the general contractor asks for a certificate, and the policy doesn't have the filing or the endorsements the contract calls for. Here's how the pieces fit together, from the permit to the paperwork a contractor will ask for.
Who needs a California Motor Carrier Permit?
The California DMV requires an MCP if you do any of the following:
- Get paid to transport property, in a vehicle of any size.
- Operate a commercial vehicle with a GVWR of 10,001 lbs or more.
- Transport hazardous materials.
- Run a vehicle combination longer than 40 feet when coupled.
A loaded dump truck hauling for a contractor checks at least two of those boxes, so an MCP is almost always part of the picture. The DMV also asks for proof of workers' compensation coverage, or a signed exemption statement if you have no employees. California DMV: Motor Carrier Permits.
How do I get a CA number from the CHP?
The California Highway Patrol issues the CA number, and the DMV won't issue your MCP without it. The order matters:
- USDOT number first. CHP guidance for new intrastate carriers says California requires a USDOT number before you can get a CA number, even if you never leave the state.
- CA number next. You submit a Motor Carrier Profile (CHP 362) that includes your USDOT number.
- MCP last. You apply to the DMV, and your insurer files the MC 65 M.
CHP also expects new carriers to keep vehicle maintenance records and hours-of-service or time records. CHP: new carrier guidance for intrastate property carriers.
What is the MC 65 M insurance filing?
The MC 65 M is a Certificate of Insurance that your insurance company files directly with the DMV. It's how the state knows you carry the required liability limit. You don't file it yourself, and not every commercial auto policy includes it, so confirm the filing before you bind.
Keep it active. The DMV's MCP handbook says your permit is suspended when your certificate of insurance lapses or is terminated and no replacement is on file. A suspended MCP means you can't legally haul for hire until it's reinstated.
How much liability does a dump truck need in California?
The DMV sets minimums from $300,000 to $5,000,000 depending on the vehicle and what's hauled. The handbook doesn't list a separate category for dump trucks or construction hauling. They fall under the general property rows:
| What you haul (California MCP) | DMV minimum liability |
|---|---|
| Property other than hazmat, vehicle 10,001 lbs GVWR or more (most dump trucks) | $750,000 |
| Property other than hazmat, vehicle 10,000 lbs GVWR or less (for-hire only) | $300,000 |
| Hazardous materials, petroleum in bulk or cargo tanks | $1,000,000 to $5,000,000 |
That's the legal floor. General contractors, public works jobs and material yards often set their own limits in the subcontract, and those are frequently higher than the state minimum. Read the insurance section of the contract before you choose a limit, not after.
What coverages does a dump truck operator actually need?
- Primary auto liability: the coverage the DMV (and FMCSA, if you cross state lines) requires. It pays for injuries and damage you cause to others.
- Physical damage: covers your own truck and trailer for collision, fire and theft. If the truck is financed, your lender will require it.
- General liability: covers claims that aren't about driving, such as damage at the job site while you're dumping or spreading a load. Contractors often require it before you're allowed on site.
- Workers' compensation: required if you have employees, and part of what the DMV checks for the MCP.
- Motor truck cargo: less common for aggregates, since dirt, gravel and base rock rarely carry much claim value. Some customers still ask for it, so check your contract.
Intrastate vs interstate: which rules apply?
If every load starts and ends in California, you're an intrastate carrier and the MCP, CA number and MC 65 M are what matter. If you haul across state lines for hire, federal rules apply on top of that:
- FMCSA requires at least $750,000 in liability for for-hire property carriers in vehicles of 10,001 lbs GVWR or more.
- If you need interstate operating authority, your insurer files a BMC-91 or BMC-91X with FMCSA and your policy carries the MCS-90 endorsement.
- A BOC-3 process agent filing is also required for authority. That's done by a process agent company, not your insurer.
Plenty of operators need both. One policy can handle the state and federal filings if it's set up for both from the start. FMCSA: insurance requirements.
What do contractors ask for on a certificate of insurance?
Before you haul, the general contractor or property owner will usually ask for a certificate of insurance (COI) that shows your coverage. It often comes with specific requests:
- Additional insured: adds the contractor to your policy for claims that come from your work. This requires an endorsement on the policy. Listing them on the certificate alone doesn't do it.
- Waiver of subrogation: your insurer agrees not to go after the contractor to recover money it pays on a claim. This also usually needs an endorsement.
- Primary and non-contributory: your policy pays first, before the contractor's own insurance.
- Specific limits and job names: the exact limits in the contract, and sometimes the project name or address.
Send us the insurance page of the contract and we'll tell you which endorsements you have and which need to be added. Most standard certificates go out the same business day.
What should I have ready before I call?
- USDOT number, CA number and MCP status (or where you are in the process)
- Driver's license for every driver, with years of experience
- VINs, years and values of trucks and trailers
- What you haul, where, and how far from your yard
- Any contracts with insurance requirements, plus prior insurance or loss history
Frequently asked questions
Do I need an MCP if I only haul my own dirt and equipment?
Possibly. The DMV requires an MCP for commercial vehicles of 10,001 lbs GVWR or more even when you are not paid to haul, so a private carrier running a heavy dump truck usually needs one. Tell us how you use the truck and we can help you confirm.
How much liability insurance does a dump truck need in California?
For property other than hazardous materials in a vehicle rated 10,001 lbs GVWR or more, the DMV minimum is $750,000 combined single limit. Contractors often ask for more, so check your contract.
Who files the MC 65 M?
Your insurance company files the MC 65 M directly with the California DMV. Make sure the policy you choose includes the filing before you bind it.
Does a dump truck need cargo insurance?
Not usually for aggregates like dirt, sand and gravel, and the DMV does not require it. Some customers still ask for it in their contracts, so read the insurance section before you decide.
What happens to my MCP if my insurance cancels?
The DMV suspends the permit when your certificate of insurance lapses or is terminated without a replacement on file. Keep payments current and call us before any change so a new filing goes in first.
