California Commercial Auto Insurance Requirements and Limits

California commercial auto insurance requirements start with a statewide liability floor of $30,000 per person for bodily injury, $60,000 per accident for bodily injury, and $15,000 for property damage on every business-operated vehicle. Those limits doubled from the previous baseline when Senate Bill 1107 took effect on January 1, 2025.¹ Many operations must carry much more, with mandatory limits climbing to $5,000,000 for the highest-risk carriers depending on vehicle weight, passenger capacity, and cargo type.

Which Vehicles Count as Commercial

California defines a commercial vehicle by how it is used and what it is built for, not who owns it. Under Vehicle Code Section 260, a motor vehicle qualifies as commercial if it carries people for hire or profit, or if it is designed or maintained primarily for hauling property.² A plumber’s van loaded with tools, a delivery truck, and a sedan carrying paying passengers all fall within the definition.

The “designed primarily for transporting property” language catches vehicles that might feel personal. A standard pickup truck is built to haul cargo, which brings it under the commercial umbrella even if the owner uses it mostly for errands. Because of that, a surprising number of sole proprietors and small businesses need commercial coverage on vehicles they think of as their own.

Minimum Liability Limits for Every Commercial Vehicle

Every commercial vehicle on California roads must meet the state’s baseline financial responsibility standard, commonly written as 30/60/15:¹

$30,000 for bodily injury or death of one person per accident
$60,000 for total bodily injury or death of all persons per accident
$15,000 for property damage per accident

These are split limits, meaning each bucket is capped separately. If one injured person’s medical bills exceed $30,000, the per-person cap applies even if the total $60,000 hasn’t been reached. The alternative structure is a combined single limit, which pools all coverage into one amount that can be allocated across injuries and property damage however needed. Combined single limits are common on commercial policies and are required for Motor Carrier Permit holders, typically starting at $300,000.³

The 30/60/15 floor is a bare minimum. A single serious-injury accident can generate six-figure medical bills, and any damages beyond your policy limits come out of the business’s own assets. Most insurers and industry advisors treat the statutory minimum as a starting point rather than a target.

Motor Carrier Permit and Higher Limits for Freight

Most businesses that haul goods in California need a Motor Carrier Permit from the DMV before they start operating. The requirement applies broadly, and it often surprises new business owners. A permit is required if you fall into any of these categories:³

For-hire property carriers, meaning any person or business paid to transport property regardless of vehicle size, including motorcycle courier services
Any commercial or private-use vehicle with a gross vehicle weight rating of 10,001 pounds or more
Any vehicle transporting hazardous materials, regardless of quantity
Motor truck and trailer combinations exceeding 40 feet in coupled length
Any vehicle or combination requiring a commercial driver’s license

The application requires a California Highway Patrol number, proof of liability insurance, proof of workers’ compensation (or a signed exemption), and enrollment in the Employer Pull Notice program if you hire drivers with commercial licenses.³ You apply online or by mail using Form MC 706 M.

Insurance limits for permit holders run from $300,000 to $5,000,000 in combined single-limit coverage, scaled to the type of vehicle and cargo. Your insurer must file a Certificate of Insurance (Form MC 65 M) directly with the DMV. Vehicle Code Section 34620 makes it illegal for a motor carrier to operate on any public highway without a valid permit, and it also prohibits anyone from hiring a carrier that doesn’t hold one.⁴

Passenger Carriers Regulated by the CPUC

For-hire passenger carriers regulated by the California Public Utilities Commission face much higher liability minimums than the 30/60/15 baseline. Charter-party carriers, the legal category covering limousines, airport shuttles, charter buses, and similar services, must carry insurance based on the vehicle’s total seating capacity including the driver:⁵

8 persons or fewer including driver: $750,000
9 to 15 persons including driver: $1,500,000
16 or more persons including driver: $5,000,000

The CPUC requires insurance companies to file proof of coverage directly with the commission, not with the DMV, before a carrier can operate. That filing must remain active for the entire duration of the carrier’s operating authority. Even a brief lapse can trigger suspension.⁶

Rideshare Drivers and TNC Coverage

Transportation Network Companies like Uber and Lyft operate under a tiered insurance structure that shifts depending on what the driver is doing at any given moment. The CPUC divides each trip into three periods with escalating coverage requirements:⁷

Period 1, app on and waiting for a match: primary coverage of at least $50,000 per person for injury or death, $100,000 per incident, and $30,000 for property damage, plus $200,000 in excess coverage per occurrence
Period 2, match accepted and en route to pick up a passenger: $1,000,000 in primary commercial liability
Period 3, passenger in the vehicle: $1,000,000 in primary commercial liability plus $1,000,000 in uninsured and underinsured motorist coverage

Either the TNC or the individual driver can carry this insurance, or the two can share it. In practice, the major platforms maintain commercial policies that cover their drivers during Periods 2 and 3. Period 1 is where gaps most commonly appear. If a driver’s personal policy excludes rideshare use and the TNC’s Period 1 coverage only kicks in as excess, the driver can end up in an uncovered window.

Federal Minimums for Interstate Carriers

Businesses that cross state lines with commercial vehicles must also satisfy federal insurance minimums set by the Federal Motor Carrier Safety Administration. Federal rules sit on top of California’s, and you have to meet both. Under 49 CFR 387.303:⁸

Non-hazardous freight, vehicle under 10,001 lbs GVWR: $300,000
Non-hazardous freight, vehicle 10,001 lbs GVWR or more: $750,000
Hazardous materials including oil, hazardous waste, and hazardous substances: $1,000,000
Explosives, poison gas, or radioactive materials: $5,000,000

The FMCSA will not grant operating authority until the carrier’s insurer files proof of coverage, typically on Form BMC-91 or BMC-91X, directly with the agency. Carriers that fail to complete this filing within 20 days of their application’s publication in the FMCSA Register face dismissal.⁹ Interstate carriers also complete Unified Carrier Registration annually and pay a fee scaled to fleet size.¹⁰

Hired and Non-Owned Auto Coverage

California follows the respondeat superior doctrine, which means employers are liable for accidents their employees cause while performing job duties. If an employee rear-ends someone while driving to a client meeting in their personal car, the injured party can sue the business, not just the driver. The employee’s personal auto policy covers them first, but when those limits run out, the claim lands on the employer.

Hired and non-owned auto coverage fills that gap. The non-owned piece covers liability when employees drive their own vehicles for work tasks like deliveries, client visits, or errands. The hired piece covers vehicles the business rents or borrows. The coverage acts as excess insurance above the driver’s personal policy limits, paying injury and property damage claims that exceed what the employee’s own insurer will cover.

This coverage does not pay for injuries to the employee themselves, damage to the business’s own property, or accidents during personal driving unrelated to work. It also won’t cover theft from the vehicle or wear and tear on a rented car. Businesses that regularly send employees out in personal vehicles without this endorsement carry a liability risk that a commercial policy can usually resolve inexpensively.

Uninsured Motorist Coverage

California law requires every bodily injury liability policy, including commercial policies, to include uninsured motorist coverage unless the policyholder specifically rejects it in writing.¹¹ The coverage pays for injuries to you or your employees when the at-fault driver has no insurance or not enough to cover the damages.

Default coverage must at least match the state’s minimum liability limits, currently 30/60/15. You can negotiate lower uninsured motorist limits with your insurer, but they cannot go below the statutory minimums, and you can reject the coverage entirely through a signed written waiver. For businesses with employees who spend significant time on the road, waiving uninsured motorist protection saves modest premium dollars while leaving the workforce exposed to hit-and-run drivers and underinsured motorists.

Proof of Insurance and Required Filings

Every driver and vehicle owner in California must carry proof of insurance in the vehicle at all times and produce it during a traffic stop or after a collision.¹² For commercial vehicles, the process for proving coverage to the DMV differs from personal cars.

Personal auto insurers report policy data electronically to the DMV, but commercial and business insurers are exempt from that electronic reporting. Instead, businesses typically submit a completed Notification of Alternative Forms of Financial Responsibility form (REG 5085) at initial registration or when transferring a vehicle into the business.¹³ Carriers regulated by the CPUC have their insurer file directly with the commission. Motor Carrier Permit holders have their insurer file a Certificate of Insurance (Form MC 65 M) with the DMV.

In each case, the business itself doesn’t submit the proof. The insurance company does, and a lapse on the insurer’s end can create a compliance problem even when premiums are current. Keeping your insurer informed of vehicle changes, permit renewals, and address updates prevents filings from falling out of sync.

Penalties for Operating Without Insurance

Driving a commercial vehicle without valid insurance exposes a business to escalating consequences. The most immediate penalty is a traffic citation. A first offense carries a fine of $100 to $200 plus penalty assessments, and subsequent violations within three years range from $200 to $500. Courts can order the vehicle impounded and require the driver to maintain proof of insurance for at least one year after conviction.

Beyond traffic fines, the DMV will suspend a vehicle’s registration if it cannot verify that insurance is in effect.¹⁴ A suspended registration means the vehicle cannot legally be driven or parked on public roads until proof of coverage is provided and reinstatement fees are paid. For carriers holding a Motor Carrier Permit, an insurance lapse can result in permit suspension or revocation, which effectively shuts down operations.

The financial exposure runs well beyond fines. If an uninsured commercial vehicle causes an accident, the business bears the full cost of injuries and property damage out of pocket. In a state where a serious injury case can produce a judgment in the hundreds of thousands of dollars, the few hundred dollars saved by skipping premiums is one of the worst trades a business owner can make.
