When you file a car crash claim, you're asking an insurance company — yours or someone else's — to pay for losses caused by a collision. The process sounds straightforward, but it moves through several distinct stages, each shaped by state law, the type of coverage involved, who was at fault, and how serious the injuries or damage turned out to be.
The first question in any car crash claim is: whose insurance are you filing with?
A first-party claim is filed with your own insurer. This applies when you're using your own collision coverage, personal injury protection (PIP), MedPay, or uninsured/underinsured motorist (UM/UIM) coverage.
A third-party claim is filed against the at-fault driver's liability insurance. Here, you're a claimant — not the policyholder — and the other driver's insurer has no obligation to treat your interests as a priority.
Which path you take depends on who caused the accident, what state you're in, and what coverages exist on both sides.
Insurance adjusters don't decide fault randomly. They review the police report, photos, witness statements, traffic laws, and sometimes accident reconstruction reports. From there, they apply their state's fault rules — which vary significantly.
| Fault Rule | How It Works | States That Use It |
|---|---|---|
| Pure comparative fault | Your recovery is reduced by your percentage of fault | CA, NY, FL (for property), and others |
| Modified comparative fault | You can recover only if you're less than 50% or 51% at fault | Most U.S. states |
| Contributory negligence | Any fault on your part can bar recovery entirely | AL, MD, NC, VA, DC |
| No-fault | Each driver uses their own PIP for medical costs; lawsuits limited | FL, MI, NY, NJ, PA, and others |
In no-fault states, your ability to step outside the no-fault system and sue the other driver often depends on whether your injuries meet a specific tort threshold — a defined level of severity set by state law.
Car crash claims generally involve two categories of damages:
Economic damages are concrete and documentable:
Non-economic damages are less tangible but often significant:
Some states also allow punitive damages in cases of egregious conduct — drunk driving, for example — though these are less common and subject to their own legal standards.
How these damages are calculated, and whether all of them are available to you, depends heavily on your state's laws and the specific facts of your accident.
What happens medically after a crash directly affects what a claim is worth. Insurers look at whether treatment was consistent, timely, and connected to the accident. Gaps in care — or waiting weeks to see a doctor — can be used to argue injuries weren't serious or weren't caused by the crash.
Typical medical trajectories after a collision include an ER visit or urgent care evaluation, followed by imaging (X-rays, MRI), specialist referrals, physical therapy, or pain management. Treatment records become the backbone of any personal injury claim.
| Coverage Type | What It Covers | Who Files |
|---|---|---|
| Liability | Injuries/damage you cause to others | The other party files against you |
| Collision | Damage to your own vehicle | You file with your own insurer |
| PIP / MedPay | Your medical costs regardless of fault | You file with your own insurer |
| UM/UIM | Accidents involving uninsured or underinsured drivers | You file with your own insurer |
Coverage limits cap what any insurer will pay. If the at-fault driver carries only minimum liability limits and your damages exceed those limits, your own UM/UIM coverage may be the only remaining source — if you have it.
Adjusters typically start with documented economic damages and apply a multiplier or formula to estimate non-economic losses. This isn't universal — different insurers, different adjusters, and different state rules produce different approaches.
The process often begins with a demand letter: a written summary of your injuries, treatment, and the amount you're seeking. The insurer responds with an offer, and negotiation follows. Many claims settle without litigation. Some don't.
Settlement timelines vary from weeks to years, depending on injury severity, whether fault is disputed, how quickly medical treatment concludes, and whether a lawsuit gets filed. Statutes of limitations — the legal deadline to file a lawsuit — vary by state and claim type, and missing them typically extinguishes your right to recover.
Personal injury attorneys typically handle car crash cases on contingency — meaning they take a percentage of any settlement or verdict (commonly 33% before trial, higher if it goes to court) rather than charging upfront fees. Representation is most commonly sought when injuries are serious, fault is disputed, an insurer is offering low settlements, or a claim involves complex coverage questions.
Attorney involvement changes the dynamic with insurers. It doesn't guarantee a different outcome, but it does mean someone is negotiating with knowledge of case value, local verdicts, and insurer behavior patterns.
Beyond the insurance claim, some accidents trigger separate obligations:
These requirements aren't automatic in every case, and the rules differ by state.
A car crash claim isn't one process — it's a series of overlapping questions: Who was at fault, and by how much? What state's laws apply? What coverage exists? How severe were the injuries? How well is the treatment documented? Is the claim disputed?
The answers don't come from general information. They come from the specific facts of your accident, your policy, and the jurisdiction where the crash happened.
