How Car Insurance Claims Work After an Accident

When a crash happens, most people know they're supposed to file an insurance claim — but the process itself is rarely straightforward. What you file, who you file with, and what happens next depends on where the accident occurred, who was at fault, what coverage is in place, and how serious the damage or injuries are.

Here's how the process generally works.

First-Party vs. Third-Party Claims

Every car insurance claim falls into one of two categories:

• A first-party claim is filed with your own insurance company — for example, using your collision coverage to repair your vehicle, or your Personal Injury Protection (PIP) to cover your medical bills.
• A third-party claim is filed against someone else's insurance — typically the at-fault driver's liability policy.

Which path applies to you depends heavily on your state's fault rules and what coverage you carry.

How Fault Is Determined

In at-fault states, the driver responsible for causing the accident is (through their insurer) generally responsible for paying damages. Fault is typically established using police reports, witness statements, photos, traffic camera footage, and adjuster investigations.

In no-fault states, each driver's own insurance covers their medical costs and certain lost wages up front — regardless of who caused the crash. In these states, your ability to step outside the no-fault system and pursue a third-party claim often depends on whether your injuries meet a defined tort threshold (either a dollar amount in medical bills or a severity standard, depending on the state).

Most states use some form of comparative negligence, meaning fault can be split between drivers. If you're found 20% at fault, your recoverable damages may be reduced by 20%. A smaller number of states still apply contributory negligence, where being even partially at fault can bar recovery entirely.

What Happens After You File 📋

Once a claim is opened, an insurance adjuster is assigned. Their job is to investigate the accident, assess liability, review documentation, and calculate what the insurer believes is owed under the policy. Adjusters work for the insurance company — not for you.

The insurer will typically:

1. Contact involved parties and witnesses
2. Review the police report
3. Inspect vehicle damage (or use photos and repair estimates)
4. Request medical records and bills if injuries are claimed
5. Issue a coverage determination and, if liability is accepted, make a settlement offer

You have the right to negotiate that offer. Many claimants accept the first offer; others negotiate, dispute the amount, or involve an attorney.

Types of Damages Generally Recoverable

Not all of these categories are available in every claim or every state. No-fault states limit certain third-party claims. Policy limits cap what an insurer will pay. Diminished value claims, for instance, are recognized in some states and not others.

Coverage Types That Often Come Into Play

• Liability coverage pays for the other party's damages when you're at fault
• Collision coverage pays to repair your vehicle regardless of fault
• PIP (Personal Injury Protection) covers medical bills and sometimes lost wages for you and your passengers in no-fault states (and some at-fault states)
• MedPay covers medical expenses regardless of fault, typically in smaller amounts
• Uninsured/Underinsured Motorist (UM/UIM) steps in when the at-fault driver has no insurance or not enough

Coverage availability and required minimums vary by state. Some of these are mandatory in certain states; others are optional add-ons.

Medical Treatment and Why It Matters in Claims 🏥

How you document and treat injuries directly affects a claim's value. Insurers review medical records to understand the nature and severity of injuries, how consistently treatment was pursued, and whether the care received connects to the accident.

Gaps in treatment — or waiting a long time before seeking care — are frequently used by adjusters to question injury severity or causation. Emergency room visits, follow-up appointments, physical therapy, and specialist referrals all create a documented record that supports a claim.

When Attorneys Get Involved

Personal injury attorneys who handle car accident cases typically work on a contingency fee — meaning they collect a percentage of any settlement or judgment, usually ranging from 25% to 40% depending on the stage of the case and the state. No recovery, no fee.

Attorneys are most commonly involved in cases with significant injuries, disputed liability, uncooperative insurers, or complex coverage issues. The decision to retain counsel — and when — is one of the more consequential choices in a claim.

Timelines and Deadlines

Statutes of limitations for personal injury and property damage claims vary by state — commonly ranging from one to six years, though some states have shorter windows. Missing a filing deadline typically bars recovery entirely.

Claims themselves can take anywhere from a few weeks (for straightforward property damage) to several years (for serious injuries involving litigation). Delays are common when liability is disputed, injuries require extended treatment, or the case moves into litigation.

DMV Reporting and License Consequences

Many states require drivers to report accidents to the DMV directly, separate from filing an insurance claim — particularly when injuries or property damage exceed a certain dollar threshold. Failing to report can have license consequences. Some accidents trigger SR-22 requirements, which is a certificate your insurer files with the state to verify you carry minimum required coverage.

What's Still Missing

The way these rules apply to any specific accident depends on the state where it occurred, the coverage policies in effect, how fault is apportioned, the severity of injuries, and dozens of other facts. What's described here is how the system generally works — not how it will work for any particular situation.
