Commercial truck insurance in California, built around your MCP

California runs its own permit for trucks on its roads, separate from FMCSA operating authority. The DMV issues the Motor Carrier Permit (MCP), and you need one if you haul property for pay in any vehicle, run a commercial vehicle of 10,001 pounds GVWR or more (private or for-hire), haul hazardous materials, or run a truck and trailer over 40 feet or one that takes a commercial license. The permit is not issued until your insurer files proof of liability coverage.

Two differences from federal rules matter most. California’s $750,000 floor applies to private carriers hauling their own goods, not only to for-hire carriers, and bulk petroleum needs $1.2 million instead of $1 million. Household movers are the exception to the whole program: they operate under a permit from the Bureau of Household Goods and Services, not an MCP (Vehicle Code 34601).

Does California require uninsured motorist coverage on a truck policy?

Yes, unless you turn it down in writing. Under Insurance Code 11580.2, an auto liability policy issued in California must include uninsured motorist coverage for bodily injury. The named insured can delete it or lower it by written agreement, and that agreement carries into renewals and replacement policies with the same insurer. The rule does not apply to excess or umbrella policies.

Usually more than the minimum, and the load decides the rest:

• Port containers: the DMV treats freight containers, loaded or empty, as interstate commerce, so a carrier that only hauls containers is not subject to the MCP even if every mile is in California. That puts you under FMCSA rules, and if you pull containers under the UIIA, the interchange contract asks for $1 million in auto liability and $1 million in general liability, plus trailer interchange and cargo coverage when a provider requires them. Drayage fleets at the Los Angeles and Long Beach ports should see our Los Angeles commercial truck insurance page.
• Produce and reefer: Caltrans’ 2023 California Freight Mobility Plan describes California as the nation’s leading agricultural exporter and says most of its produce travels by truck for all or part of the trip, with fruit, vegetables, and meat moving in refrigerated trailers. Motor truck cargo coverage protects the load, with reefer breakdown and spoilage options.
• Box trucks and local delivery: a two-axle box truck over 10,000 pounds GVWR needs an MCP and $750,000 even when you haul only your own goods; a lighter truck hauling for pay needs $300,000. Our box truck insurance page covers the rest of the policy.
• Fuel and hazmat: bulk petroleum inside California needs $1.2 million, and bulk hazardous substances need $5 million under both state and federal rules.
• General freight: the MCP liability rule covers injuries and damage to other people’s property, not the goods you carry, and FMCSA requires no cargo coverage for general freight. Brokers and shippers can still require it by contract.

Most operations add physical damage for their own tractors and trailers, general liability, and non-trucking liability for owner-operators leased to a carrier. Our commercial truck insurance page lists every line we place.

Your insurer files proof of coverage with the DMV; buying the policy is not enough. For an MCP, that proof is the MC 65 M certificate, and it has to cover every vehicle you run under the permit.

How do you keep your MCP from being suspended?

• Notice: an MC 65 M cannot be canceled on less than 30 days’ written notice to the DMV, counted from the day the DMV receives it. Interstate policies need 35 days’ notice under 49 CFR 387.7.
• Lapse means suspension: if coverage ends without a new MC 65 M on file, the permit is suspended on the cancellation date, for an indefinite period, and you cannot run until a new certificate is filed. A reinstatement fee applies unless you show there was no actual gap.
• Primary and excess: you can stack primary and excess policies to reach the limit, but if the primary is canceled the permit is suspended. Two separate primary policies cannot be combined.
• Closing down: file a voluntary withdrawal (MC 716 M) before you cancel the insurance, or you may owe delinquency fees if you return.
• Customers check: under Vehicle Code 34620, no one may hire a motor carrier of property that lacks a valid MCP, and a carrier that subcontracts a load must first get a certification and a copy of the other carrier’s permit.
