When a car accident happens, most people know they're supposed to file a claim — but few understand what actually happens next. The process involves insurers, adjusters, documentation, fault determinations, and sometimes attorneys. Here's how it generally works.
Every car insurance claim falls into one of two categories:
Which path applies depends on your state's fault system, the type of coverage involved, and who was responsible for the crash.
In at-fault states, the driver who caused the accident is generally responsible for the resulting damages. Insurers investigate to assign fault — using police reports, photos, witness statements, traffic camera footage, and sometimes accident reconstruction specialists.
No-fault states work differently. Regardless of who caused the crash, each driver's own insurance pays for their medical expenses up to a certain limit. Only when injuries meet a certain severity threshold — called a tort threshold — can an injured person step outside the no-fault system and pursue a claim against the at-fault driver.
Fault assignment also varies by how states handle shared responsibility:
| Fault Rule | How It Works |
|---|---|
| Pure comparative fault | You can recover damages even if you're mostly at fault, reduced by your percentage |
| Modified comparative fault | You can recover only if your fault is below a certain percentage (often 50% or 51%) |
| Contributory negligence | In a small number of states, any fault on your part may bar recovery entirely |
Once a claim is submitted, the insurer assigns an adjuster — an employee or contractor who investigates the accident, reviews documentation, evaluates damages, and determines what the policy covers.
The adjuster will typically:
For property damage, resolution is often relatively straightforward. For injury claims, the process takes longer — insurers generally want to see how injuries resolve before making a final settlement offer. Settling too early can mean accepting compensation before the full extent of injuries is known.
Depending on fault, coverage, and state law, compensation may be available for:
Not all of these categories are available in every claim, and how they're calculated varies significantly by state and policy.
| Coverage Type | What It Generally Does |
|---|---|
| Liability | Pays for damages you cause to others |
| PIP (Personal Injury Protection) | Pays your medical bills and sometimes lost wages, regardless of fault |
| MedPay | Covers medical expenses for you and passengers, regardless of fault |
| Uninsured/Underinsured Motorist (UM/UIM) | Covers you when the at-fault driver has no insurance or not enough |
| Collision | Pays to repair your vehicle after a crash, regardless of fault |
Coverage limits — the maximum an insurer will pay — matter enormously. A policy with a $25,000 bodily injury limit may not cover the full cost of serious injuries, which is where underinsured motorist coverage becomes relevant.
Treatment records are a foundational part of any injury claim. Insurers use them to evaluate the nature, severity, and cost of injuries. Gaps in treatment — periods where someone stops receiving care and then resumes — can complicate how a claim is evaluated.
After a crash, many people seek emergency care, then follow up with primary care physicians, specialists, orthopedists, or physical therapists. The documentation generated throughout that process becomes the basis for calculating medical damages.
Personal injury attorneys typically handle car accident cases on a contingency fee basis — meaning they take a percentage of any settlement or judgment rather than charging upfront. That percentage varies but commonly falls between 25% and 40%, depending on the case and whether it goes to trial.
Legal representation is more commonly sought in cases involving serious injuries, disputed fault, unresponsive insurers, or situations where a settlement offer appears to undervalue the claim. Whether or how to involve an attorney is a decision that depends entirely on the specifics of a given situation.
Statutes of limitations — the legal deadlines for filing a lawsuit — vary by state. Most fall somewhere between one and four years from the date of the accident, but exceptions exist, and missing the deadline typically eliminates the right to sue.
Some states also require DMV reporting after accidents above a certain damage threshold. Drivers involved in serious accidents may face license consequences, and those who caused crashes while uninsured may be required to file an SR-22 — a certificate of financial responsibility — to maintain or reinstate their license.
Subrogation is another term worth knowing: if your insurer pays your claim and you later recover from the at-fault party, the insurer may have the right to be reimbursed from that recovery.
No two claims work out identically. The state where the accident occurred, the type of coverage in place, the severity of injuries, how fault is assigned, whether the at-fault driver was insured, and the specific terms of each policy all feed into how a claim proceeds — and what it ultimately resolves for.
General information explains the framework. Your state, your policy, and the specific facts of your accident are what determine how that framework actually applies.
