Direct answer
What should I do after a car accident that wasn't my fault?
After a car accident that was not your fault, get medical care, gather the other driver's insurance details and the report number, and notify your own insurer as your policy requires. You will usually deal with the other driver's insurance company for the injury claim — be careful with recorded statements to them, since their job is to minimize what their driver's policy pays. Being blameless does not make the claim automatic; it still has to be documented and, often, negotiated.
It feels like it should be simple: the other driver caused it, so their insurance pays. In practice, the other driver's insurer works for the other driver, and even a clear-fault claim gets tested — on your injuries, your treatment, and your words. Here is how to keep a clean claim clean.
Fault helps you — but you still prove the claim
Liability and damages are separate questions. Even when fault is obvious, the insurer will still examine whether you were really hurt, whether your treatment matches the injury, and whether some blame can be shifted your way under California's comparative-fault rules. Photographs, the police report, prompt medical care, and consistent treatment are what convert “not my fault” into a documented claim.
Do not assume the police report settles everything. Reports help, but insurers contest them, and reports sometimes contain errors you can ask to correct.
Two insurers, two very different relationships
Your own insurer: notify them promptly as your policy requires, cooperate with reasonable requests, and use coverages you paid for — medical payments coverage or a rental, for example. Claims under your own policy generally should not raise your rates when you were not at fault, though practices vary.
The other driver's insurer: everything is negotiation. You are generally not required to give them a recorded statement, and early friendly calls are how low settlements begin. It is reasonable to decline politely and speak with an attorney first — especially if you were injured.
When the not-at-fault claim still needs a lawyer
If your injuries required treatment, if the insurer disputes anything, if the offer arrives fast and small, or if the at-fault driver was uninsured, the claim has left simple territory. A California attorney handles the insurer contact, values the full claim including future treatment, and costs nothing up front on contingency.
Common questions
The other driver admitted fault at the scene. Is my claim safe?
Helpful, but not decisive — people change their accounts once insurers are involved, and admissions at the scene are disputed later more often than you would expect. Keep your evidence anyway: photos, witnesses, and the report number are what hold the story in place.
Should I use my own insurance if the accident wasn't my fault?
Often yes, for what it covers — your policy may pay for medical care or vehicle repair faster, and your insurer can seek reimbursement from the at-fault driver's insurer. Notify your insurer as the policy requires regardless; failing to report can create its own problems.
The at-fault driver's insurer offered me money already. Take it?
Be careful. Very early offers usually arrive before the full extent of an injury is known, and accepting typically means signing a release that ends the claim permanently. Before signing anything, it is reasonable to have the offer reviewed — a free case review costs nothing and closes no doors.
