Commercial auto insurance in California covers vehicles used for business, from a single van to a full fleet. It pays for liability when your driver causes an accident and can add coverage for physical damage to your vehicles. Personal auto policies often exclude business use, so a commercial policy is usually the safer fit.

What does commercial auto insurance cover?

A commercial auto policy typically includes liability coverage for injuries and property damage you cause with a business vehicle, and can add collision, comprehensive, medical payments and uninsured motorist coverage. Defense costs and settlements are handled according to the policy terms, limits and any endorsements that apply to your operations.

Liability for injuries and damage your drivers cause
Collision and comprehensive coverage for your vehicles
Uninsured and underinsured motorist protection
Medical payments for occupants, where included
Optional coverage for rental or substitute vehicles

Coverage is built around how you use each vehicle, so describe your operations carefully.

Drive Safely, Operate Confidently. Your vehicles are essential to daily operations and revenue. The right commercial auto insurance prevents an accident from becoming a major financial setback and protects the cash flow you rely on.

When do I need commercial auto instead of personal auto?

You generally need commercial auto when a vehicle is owned by the business, carries tools or goods, transports customers, or is used for work beyond ordinary commuting. Personal auto policies commonly limit or exclude business use, so a claim could be denied if the policy does not match how the vehicle is really used.

Rules differ by carrier and by type of use, so confirm your situation with a licensed agent before you rely on a personal policy.

Covering Your Vehicles and Operations. We protect vehicles, cover injury liabilities, and defend against lawsuits. Strong coverage keeps your operations running, preserves revenue, and protects the financial foundation you’ve built.

Does commercial auto cover employees who drive their own cars?

Not by default. Coverage for vehicles you do not own, such as an employee’s car used on an errand, is called hired and non-owned auto liability. It is often added to a commercial policy or to general liability, and it protects the business if an employee causes an accident while working.

If staff sometimes drive for work, mention it when you request quotes so the right endorsement is included.

What is not covered by a commercial auto policy?

Commercial auto does not typically cover cargo you are hauling, tools and equipment inside the vehicle, injuries to your own employees, or intentional acts. Those exposures usually need motor truck cargo, inland marine or equipment coverage, and workers’ compensation, which is why programs are built from several policies.

A review of your exposures can show where a gap sits between the auto policy and your other coverage.

Frequently asked questions

Do I need commercial auto for just one work van?

Usually yes, if the van is used for business or owned by the company. A single vehicle can cause a serious loss, and a personal policy may not respond to work use.

Can I add and remove vehicles during the year?

Yes. Policies can generally be updated as your fleet changes. Tell your broker when you buy, sell or retitle a vehicle so coverage stays accurate.

Are my drivers’ records important?

Yes. Carriers review driving records when they price and approve a policy, and some require drivers to meet standards. Clean records and written driver policies can help your options.

Does commercial auto cover rented vehicles?

Sometimes. Hired auto coverage can extend liability to rented vehicles, but physical damage rules vary. Check the policy and the rental agreement before you rent for work.
