Accident in a Borrowed Car: Whose Insurance Pays

A standard auto policy insures the vehicle listed on it and covers the named insured, their household members, and any other person using the vehicle with permission. When a friend borrows your car and causes a crash, your policy is the primary coverage: it pays the injured person's claim up to your liability limit, and your insurer defends the friend. The friend's own policy, if they have one, is excess, paying only what your policy does not. This is the rule in most states and under most policies.

The consequences run both ways. If you lend your car, your policy and your premium bear the crash. If you borrow one, the owner's policy is the first line and your own is behind it. The injured person, who did not choose any of this, has claims against both policies and pursues them in order.

A few policies and a few states vary the rule: some policies make the driver's coverage primary for certain situations, some states have statutes placing the owner's coverage first expressly, and commercial and rental arrangements have their own structures. The policy language and the state's law decide the order, and an attorney checks both in a borrowed-car claim.

Coverage under the owner's policy depends on permission. Express permission, the owner handed over the keys, is clear. Implied permission, a roommate who regularly uses the car, a family member with a standing arrangement, is usually found from the course of conduct. The disputes arise when the owner denies permission, when the driver was a friend of a permitted driver rather than the owner, or when the driver used the car for something or somewhere beyond what was allowed. Insurers investigate permission closely because it is their way out.

Named-driver exclusions are the other exit. An owner who excluded a household member, a teenage child or a spouse with a bad record, to lower the premium, has a policy that does not cover that person's driving at all, and many states enforce the exclusion against injured third parties. A crash caused by an excluded driver in a borrowed car may be uncovered by the owner's policy entirely, leaving the driver's own policy, if any, and the injured person's UM coverage.

A driver who took the car without permission is not a permissive user, and the owner's policy does not cover them; the crash is treated like one involving a stolen vehicle, and the injured person's UM coverage responds. Owners sometimes deny permission after a crash to protect their policy, and the driver's account, the relationship and the history of use are the evidence.

Suppose you were struck at an intersection by a driver who ran a stop sign in a car belonging to her brother, which she had borrowed for the afternoon with his permission. You suffered a fractured ankle requiring surgery, with $43,000 in medical bills and ten weeks off work. The brother's policy carried $50,000 per person; the sister had her own policy on her own car with $100,000.

The brother's insurer accepted that its policy was primary and that the sister was a permissive user, after confirming with the brother that he had lent the car. It paid the $50,000 limit. The sister's own insurer, as the excess carrier, was then presented with the balance of the claim, and after disputing the ankle's lasting limitation, paid a negotiated amount within its limit.

Had the brother denied lending the car, or had the sister been a named excluded driver on his policy, the claim would have gone to her policy alone, with your own underinsured motorist coverage behind it. Had she had no policy of her own, which is common for people who do not own a car, the claim would have been capped at the brother's $50,000 plus your UM coverage. All figures are hypothetical.

The usual steps apply, with several aimed at the ownership and permission questions.

• Photograph the car's registration and insurance card, which identify the owner and the owner's insurer, as well as the driver's license.
• Ask the driver whose car it is and why they were driving it, and write down the answer; the permission question starts here.
• Tell the police the driver was not the owner and make sure the report identifies both.
• Report the crash to the owner's insurer and to the driver's insurer, if any; both claims are opened from the start.
• Get medical care the same day; the coverage questions do not change the need to document the injury.
• Identify your own uninsured and underinsured motorist coverage immediately, because a permission dispute or an exclusion can leave the owner's policy out of the picture.
• If the owner knew the driver was unsafe, unlicensed or impaired, tell your attorney; negligent entrustment puts the owner personally on the claim.

Whether insurance follows the car or the driver is a matter of policy language and state law, and most states follow the car. A few states have owner liability statutes that go further: New York, Florida, Michigan, California within limits, and others make the vehicle's owner personally liable for the negligence of any permissive driver, regardless of the owner's own conduct, which places the owner and their assets on the claim and not merely their policy. The family purpose doctrine in other states does the same for family members' use of a family car.

Named-driver exclusions are enforced against third parties in many states and prohibited or limited in a few, where the state's financial responsibility law requires the policy to cover any permissive driver at least to the minimum limits. Whether a borrowed-car crash caused by an excluded driver leaves the injured person with nothing from the owner's policy depends on the state. Uninsured motorist coverage on the injured person's policy responds where the owner's policy does not.

Comparative negligence applies to the injured person's own conduct under each state's rule. In no-fault states, the injured person's own PIP pays first regardless of whose car was involved, and the claim against the driver and owner proceeds above the threshold. Deadlines are the state's injury statute, one year in Tennessee and Kentucky, two in Texas, California, Florida and Georgia, three in New York and North Carolina.

Rental cars follow a different structure. The renter's own policy usually extends to a rental car, the rental company's coverage applies in limited amounts and only if purchased or required by state law, and a credit card may provide collision coverage. A person injured by a rental car driver claims against the driver's own policy, any coverage purchased from the rental company, and the rental company's minimum financial responsibility, which in most states is the state minimum. Rental companies are generally shielded from vicarious liability for their renters' driving by federal law.

Peer-to-peer car-sharing, where an owner rents their car through an app, is governed by state statutes in most states that require the platform to provide liability coverage during the rental period and that treat the owner's personal policy as not applying. A person injured by a car-sharing driver claims against the platform's coverage, usually at or above the state minimum, and the driver's own policy.

A borrowed company car or a car driven on an employer's business brings the employer's commercial policy and the employer's liability for its employee's driving, which is the best-insured version of a borrowed-car claim.

A borrowed-car claim is a claim against two policies in order, the owner's and the driver's, with the owner's insurer looking for a permission or exclusion defense and the owner sometimes personally liable under state law. The questions to answer early are who owned the car, whether permission existed and what the owner's policy says about the driver, what the driver's own coverage is, and what UM coverage the injured person has. Most personal injury attorneys work on contingency.

Ask Legal Matters is a free claim-review request service, not a law firm. Requests may be shared with independent attorneys and legal services partners who handle inquiries in your state, and an attorney must evaluate the facts before anyone can say what the claim is worth. If you were hurt by someone driving a borrowed car, or lent your car and are facing a claim, you can request a free claim review.
