Hit by a Borrowed or Rental Car in California: Who Pays

The driver who hit you was in a friend's car, a parent's car, or a rental with a barcode on the window. Now you have two names, maybe two insurance companies, and nobody is rushing to claim the crash as theirs. This post explains who can be responsible when the driver did not own the car, which insurance usually pays, and what changes when the car is a rental.

Two people, two possible sources of money

When the driver and the owner are different people, your claim can point in two directions.

The driver is responsible for their own careless driving, just as in any crash. That part does not change because they borrowed the keys.

The owner can be responsible too, even if they were nowhere near the scene. California Vehicle Code § 17150 makes every owner of a motor vehicle liable for death or injury resulting from a negligent or wrongful act in the operation of that vehicle by anyone using it with the owner's permission, express or implied.

"Implied" matters. The owner does not have to have said yes out loud. A pattern of letting a roommate take the car whenever they need it can be enough. Expect the owner's insurer to look hard at this question, because "they took it without asking" is the cleanest way out of the claim.

The owner's personal liability is capped low

Here is the catch that surprises people. The owner's liability under § 17150, when it does not come from an employer-employee or agency relationship, is limited by § 17151 to:

• $15,000 for the death of or injury to one person in one accident
• $30,000 for more than one person in one accident
• $5,000 for damage to property

Those numbers are lower than the state's current minimum insurance requirements. The DMV lists the minimum liability coverage as $30,000 for injury or death to one person, $60,000 for more than one person, and $15,000 for property damage. The owner-liability cap in § 17151 still reads 15/30/5.

So owner liability is a floor, not a jackpot. It matters most when the driver has no insurance of their own and few assets. If the driver was working for the owner, for example running an errand for a business, the cap does not limit a claim based on that employment relationship, and the picture can look very different. Our post on being hit by a delivery driver covers that angle.

Insurance usually follows the car

The statutory cap on the owner is only part of the story, because the owner's insurance policy usually covers the borrower directly.

California Insurance Code § 11580.1 requires an auto liability policy to cover not only the named insured but any other person using the vehicle with the named insured's express or implied permission. In practice, a friend who borrows the car is usually an insured under the owner's policy, up to that policy's full limits, not just the § 17151 cap.

If the borrower also has their own car insurance, now there are two policies. Insurance Code § 11580.9(d) generally decides who goes first: the policy on which the vehicle is described or rated as an owned automobile is presumed primary, and the other policy is excess. In plain terms, the car owner's insurer usually pays first, and the driver's own insurer may pay on top of that once the first policy is used up.

That stacking matters when your injuries are serious. Two policies at $30,000 each are not the same as one.

The named driver exclusion

One exception to watch for. Insurance Code § 11580.1(d) lets an insurer and a policyholder agree in writing that the policy will not cover a specific person, designated by name, while they drive. If the borrower was excluded by name on the owner's policy, the insurer can refuse to cover that driver, and the exclusion also reaches negligent entrustment claims against the owner for handing them the keys. Ask the owner's insurer directly, in writing, whether any named driver exclusion is on the policy.

When the car is a rental

Rental cars run on a different rule. A federal statute, 49 U.S.C. § 30106, often called the Graves Amendment, says a company in the business of renting or leasing vehicles is not liable under state law simply because it owns the car, for harm arising from the use of the vehicle during the rental.

Two limits on that protection matter to you:

• The company's own fault. The federal shield applies only if there is no negligence or criminal wrongdoing on the part of the owner. If the crash traces back to something the rental company did, such as renting out a car with a known defect it should have fixed, the company can still be answerable for its own conduct.
• Financial responsibility laws. The statute expressly does not override state laws imposing financial responsibility or insurance standards on vehicle owners, or state laws holding rental businesses liable for failing to meet those requirements.

The practical result: your claim is usually against the renter and whatever coverage applies to them. That may be the renter's personal auto policy, a supplemental liability product they bought at the counter, coverage through the rental company, or a combination. Insurance Code § 11580.9(b) sets an order of payment for some rentals, making the rental company's coverage for the renter excess over the renter's own insurance, but only if the vehicle is a commercial vehicle or has been leased for six months or longer. For a weekend rental sedan, the order of payment is a question for the policies themselves.

Get the rental agreement number, the rental company's name, and the renter's own insurance information at the scene if you can. Those details are much harder to pin down later.

What this means in California

None of the borrowed-car rules changes your deadlines. Under CCP § 335.1, you generally have two years from the date of injury to file a personal injury lawsuit, and that includes a claim against an owner under § 17150. If a public entity is involved, for example a city-owned vehicle driven by an employee, a government claim is usually due within six months.

California's pure comparative negligence rule applies as usual. If an insurer argues you were partly at fault, your recovery is reduced by your share rather than eliminated.

And if every available policy still adds up to less than your losses, your own coverage may help. Our post on uninsured and underinsured drivers explains how that gap coverage works, and the post on policy limits demands explains how to approach an insurer when your claim is worth more than its limit.

Practical next steps

At the scene or soon after, write down the driver's name and insurance, the registered owner's name, and the plate. If it is a rental, photograph the rental agreement or ask the driver for the company and agreement number. Report the crash to your own insurer. Send written notice of the claim to every insurer you identify: the owner's, the driver's, and any rental coverage. Ask each one, in writing, for its policy limits and whether it is accepting coverage for this driver. Do not settle with one insurer until you know whether another policy sits behind it, because a release can end claims you did not mean to give up.
