Consumer Legal Issue
I was not found at fault for causing an accident. The other car's passenger is trying to sue me for his medical bills.
Attorney Answer
Yes, he can sue you, and the fault finding you are relying on does not stop him. Whoever decided you were not at fault — a police officer, an insurance adjuster, or the other carrier — was not a court. A civil case decides fault over again, on its own evidence.
This surprises almost everyone, and it is worth understanding why. A police report records an officer's opinion based on what was visible and said at the scene. An insurer's liability decision is a business judgment about its own exposure. Neither one is a judgment, and neither one binds the judge or jury who will hear the passenger's claim. That is a general principle of how civil cases work rather than a rule this page can point to a statute for, and a local attorney should confirm how it applies to the record in your case.
What the passenger has to prove is set by Civil Code § 1714(a): "Everyone is responsible, not only for the result of his or her willful acts, but also for an injury occasioned to another by his or her want of ordinary care or skill in the management of his or her property or person, except so far as the latter has, willfully or by want of ordinary care, brought the injury upon himself or herself." He must show you failed to use ordinary care and that it caused his injuries. If he cannot, the fact that he filed a lawsuit changes nothing.
There is a second reason passengers sue every driver. A passenger is almost never at fault for the crash himself, so the only real question in his case is how the blame divides between the drivers. California does not decide fault all-or-nothing. In Daly v. General Motors Corp., 20 Cal. 3d 725 (1978), the California Supreme Court reaffirmed and applied the state's pure comparative system, holding that recovery is reduced in proportion to a party's share of the fault rather than eliminated. So a passenger who names both drivers is not saying you were the cause — he is making sure that whatever share is eventually assigned to you is available to him.
Be honest with yourself about one thing: the earlier finding is useful evidence and a good sign, but it is not a shield.
What you can do
1. Give the lawsuit, the claim letter, or anything else you have received to your auto insurer immediately, in writing, and keep proof you sent it. Your policy has its own prompt-notice requirement, and this is the step that puts the carrier's lawyers on it rather than you.
2. Do not answer the passenger, his lawyer, or his insurer yourself. Direct every contact to your carrier.
3. Preserve what already exists — the police report number, photos, dashcam or vehicle-data recordings, repair estimates, and the names of any witnesses already identified. Do not rewrite your account of the crash for anyone but your own lawyer.
4. If you have been served with court papers rather than just a demand letter, tell your insurer today. A served defendant has a short deadline to respond that is set by court rules, and missing it can lead to a default judgment.
5. Ask a local attorney whether your policy limits are likely to cover this claim, and what happens if they do not.
6. Most lawyers offer a brief initial call at no cost, and a few minutes on your specific facts is worth more than any general guidance, including this page.
⏱ Time limits apply. A personal injury claim in California runs under Code Civ. Proc. § 335.1, which allows two years for an action for injury to an individual caused by another's wrongful act or neglect. Code Civ. Proc. § 352(a) can extend that where the injured person was a minor or lacked legal capacity when the claim accrued, and vehicle damage runs three years under Code Civ. Proc. § 338(c)(1). When the clock started, and whether it has run, depends on your facts and on when anything was actually filed. Have a local attorney check the dates.

- Daly v. General Motors Corp., 20 Cal. 3d 725 (1978) — California Supreme Court
The Supreme Court reaffirmed and applied California's pure comparative system, under which a party's recovery is reduced in proportion to their own share of fault rather than eliminated. Cited because apportionment among multiple drivers is the sentence that answers this reader's question, and Civ. Code § 1714(a)'s text does not state it.

Frequently Asked Questions
Can a passenger sue a driver who was not found at fault for the accident?
Yes. A police officer's conclusion or an insurance company's liability decision is not a court judgment and does not bind the judge or jury in a civil case; fault is decided again on the evidence presented there. Under Civil Code § 1714(a) the passenger still has to prove the driver failed to use ordinary care and that the failure caused the injuries. An earlier no-fault finding is useful evidence for the defense, not a bar to the claim.
Why do injured passengers sue every driver involved in a crash?
Because a passenger is rarely at fault for the collision, the only real question in a passenger's case is how blame divides between the drivers. California does not decide fault all-or-nothing: *Daly v. General Motors Corp.*, 20 Cal. 3d 725 (1978), reaffirmed and applied the state's pure comparative system, under which a party's recovery is reduced in proportion to that party's own share of fault. Naming every driver keeps each driver's insurance available.
What should a driver do after receiving a lawsuit or claim from a crash?
Send it to your own auto insurer immediately and in writing, and keep proof you did. Auto policies impose prompt-notice duties, and late notice can jeopardize the defense the insurer would otherwise provide. Route all contact from the other side to the carrier rather than answering it yourself, preserve the records that already exist, and, if court papers have actually been served, act the same day — the deadline to respond is short and set by court rules, and missing it can produce a default judgment.
