In California, who you carry for decides your box truck paperwork. Haul other people's goods for pay and you need a Motor Carrier Permit at any size. Deliver your own products as a private carrier and the permit generally starts with a two-axle truck over 10,000 pounds GVWR. Household movers are different again: the CHP says vehicles operated under a household mover permit are outside the MCP definition. Liability is $300,000 at 10,000 pounds or less and $750,000 above. Fuel matters too, since Clean Truck Check targets non-gasoline trucks over 14,000 pounds GVWR, so a gas 16-foot and a diesel 26-foot get treated differently. Local delivery firms should also budget for workers' comp, which DMV requires you to prove or exempt.
Box trucks are straight trucks with an enclosed body, used for final-mile delivery, furniture and appliances, moving, and local LTL. Many run under 26,000 pounds, so no CDL is needed for non-placarded loads, but that does not mean no rules. City streets, tight docks, lift gates and frequent stops drive the claims. Whether you move your own goods, freight for hire, or household goods can change the filings and limits.
What it costs
Across 6 policies Protec sold in 2026, commercial auto liability for this type of truck ran about $9,400 to $16,400 per truck per year, with a middle of $11,700. That's before taxes and fees, mostly from new and small Texas carriers, so your state and record can move it. It isn't a quote.
Filings in California
Running in California? You need a Motor Carrier Permit (MCP) from the California DMV. For-hire carriers need it for any motor vehicle, regardless of type or size, according to the CHP. Private carriers generally need it for a truck of two or more axles rated over 10,000 pounds GVWR, truck tractors, and certain other vehicles. Before the permit, you get a CA number from the California Highway Patrol (CHP) by filing a Motor Carrier Profile (CHP 362).
Minimum liability (combined single limit): $300,000 for non-hazardous property in vehicles of 10,000 pounds GVWR or less, and $750,000 for vehicles of 10,001 pounds or more. Hazmat requires $1,000,000 to $5,000,000.
Filings: your insurance company provides the Certificate of Insurance (MC 65 M). You also prove workers' compensation or sign an exemption statement, even if you employ only family. DMV may suspend the MCP if liability or workers' comp lapses.
If you cross state lines, the federal rules apply. A for-hire carrier of general freight in interstate commerce with vehicles of 10,001 pounds GVWR or more needs at least $750,000 under 49 CFR 387.9. The policy carries the MCS-90 endorsement, and your insurance company, not you, files the BMC-91 or BMC-91X with FMCSA. Hazmat limits run higher.
The limit is the same $750,000 for most heavier trucks, but the BMC-91 goes to FMCSA and does not replace the MC 65 M filing with DMV.
