How the Car Insurance Claim Process Works, Step by Step

Most people file a car insurance claim once or twice in their whole life, so nobody really knows the routine. The insurer does this thousands of times a day. That gap in experience is where a lot of money gets lost, not through anything dramatic, but through small missteps: calling the wrong company first, saying too much on a recorded line, or signing a release before treatment is finished.

This guide walks through the car insurance claim process from the moment of the crash to the day the check clears. It covers property damage and injury claims, because most accidents involve both, and they move at very different speeds.

The short version

1. Make the scene safe, call police if anyone is hurt, and collect information.
2. Tell your own insurer about the accident.
3. Decide whose insurance you are claiming against.
4. Get a claim number and an adjuster.
5. Give a statement, carefully.
6. Get the car inspected and an estimate written.
7. Repair the car or settle a total loss, and sort out a rental.
8. Treat any injuries and keep every record.
9. Send a demand and negotiate the injury claim.
10. Sign a release and get paid.

The rest of this page explains each step and the mistakes people commonly make along the way.

Step 1: At the scene

Safety comes first. Move to a safe spot if you can, turn on hazard lights, and call 911 if anyone is hurt. Then gather what the claim will need later:

• The other driver's name, phone number, license number, insurer and policy number
• Plate numbers and the make, model and color of every car
• Photos of all vehicles, the road, traffic signs, skid marks and any injuries
• Names and numbers of witnesses
• The police report number, if officers came

Do not argue about fault at the scene and do not apologize in a way that sounds like admitting it. Our full after-a-crash checklist has the complete list, including what to do in the first week.

Step 2: Tell your own insurer

Almost every auto policy requires you to report an accident "promptly," even when you were not at fault and even if you plan to claim against the other driver. Late notice is one of the easiest reasons for an insurer to push back later, so call or use the app within a day or two.

Reporting an accident is not the same as filing a claim on your own coverage. You can report it, explain that you will be claiming against the other driver, and still keep your options open.

Step 3: First-party or third-party claim?

This is the decision that shapes everything else.

	First-party claim	Third-party claim
Whose insurer	Your own	The at-fault driver's
Coverage used	Collision, MedPay or PIP, uninsured motorist	Their bodily injury and property damage liability
Deductible	Usually yes, for collision	No
Speed	Often faster	Can be slower, fault must be accepted
Who they owe a duty to	You, under your contract	Their own policyholder

A common approach when the other driver is clearly at fault is to file with their insurer, and fall back on your own collision coverage if they delay or dispute fault. If your insurer pays first, it can try to recover the money from the other side through a process called subrogation, and you may get your deductible back when it succeeds.

In no-fault states, your own personal injury protection (PIP) pays your medical bills first no matter who caused the crash. Our guide to at-fault vs no-fault states explains what changes.

Step 4: Claim number and adjuster

Once the claim is opened you get a claim number. Write it down and put it on every email, letter and document you send. Within a few days an adjuster is assigned. Sometimes there is one for the car and a separate one for injuries.

Ask the adjuster for their direct email and phone, and ask how they prefer to receive documents. From this point, try to keep important communication in writing so there is a record of who said what.

Step 5: The recorded statement

The adjuster will usually ask for a recorded statement. With your own insurer, your policy generally requires you to cooperate. With the other driver's insurer, you are usually not required to give one, and you can ask to answer questions in writing instead.

If you do give a statement:

• Stick to facts you know. "I don't know" is a complete answer.
• Do not guess speeds, distances or times.
• Do not describe your injuries as "fine" or "just sore." Say you are still being evaluated.
• Do not agree to sign a broad medical authorization on the spot. Ask what records they need and send those.

Step 6: Inspection and estimate

The insurer will inspect the car in person, through photos in its app, or at a body shop. The result is a repair estimate. In most states you can choose your own repair shop; the insurer may suggest one from its network, but you are not required to use it.

If the shop finds hidden damage after taking the car apart, it sends a supplement to the insurer for the extra work. This is normal and common.

Step 7: Repair, total loss and rental

If repair costs come close to the car's value, the insurer may declare it a total loss and pay you its actual cash value instead of fixing it. That process has its own rules and its own room for negotiation.

While the car is out of service, you may be owed a rental or "loss of use" compensation. With a third-party claim, the at-fault driver's insurer generally pays for a comparable rental for a reasonable repair period. With a first-party claim, rental coverage depends on whether you bought it.

After the repair, remember that the car is now worth less on the resale market, even if the work is perfect. That loss is called diminished value, and many drivers never claim it. Our diminished value calculator shows what the insurer formula would pay, and our guide on diminished value claims explains how to ask for it.

Step 8: Treatment and records

Injury claims move slowly on purpose. You generally should not settle an injury claim until you have finished treatment or your doctor says you have reached maximum medical improvement, because once you sign a release you cannot reopen it.

In the meantime, keep:

• Every medical bill and record, including physical therapy and prescriptions
• Proof of missed work from your employer
• Receipts for out-of-pocket costs such as mileage to appointments
• A short daily journal of pain, sleep and activities you missed

Step 9: Demand and negotiation

When treatment ends, you or your attorney send a demand letter that lists your damages, explains why the other driver is responsible, and asks for a specific amount. Our demand letter generator builds one for free, and our settlement calculator helps you choose a realistic number.

The adjuster then responds with an offer, usually lower than your demand. Our guides on how adjusters calculate offers and whether to accept the first offer cover this stage in depth.

Step 10: Release and payment

When you agree on a number, the insurer sends a release. Signing it ends the claim forever, so read it carefully. Then the insurer issues payment, which often takes a few weeks. If you have a lawyer, the check usually goes to the lawyer's trust account, where fees, costs and medical liens are paid before your share is sent to you. Our take-home calculator shows what that split looks like.

How long does the whole process take?

Property damage claims often wrap up within a few weeks. Injury claims commonly take several months, and more if injuries are serious or fault is disputed. Our guide on how long a car accident settlement takes breaks down the timeline.

Rules the insurer has to follow

Most states have adopted a version of the NAIC's Unfair Claims Settlement Practices model law. In general terms, these rules require insurers to acknowledge claims and respond to communications promptly, to investigate in a reasonable time, and not to misrepresent policy terms or force people to sue by offering clearly unreasonable amounts. The exact deadlines differ by state. If an insurer stops responding, a polite written follow-up that mentions the dates you have been waiting is usually the first step, and a complaint to your state's insurance department is the next.

Frequently asked questions

Should I file a claim with my insurer or the other driver's?

If the other driver is clearly at fault, many people claim against their insurer first because there is no deductible. If that insurer delays or disputes fault, your own collision coverage can pay and then try to recover the money later.

Do I have to report an accident to my insurer if it was not my fault?

Most policies require prompt notice of any accident. Reporting it is not the same as claiming on your policy, and it protects you if the other side later disputes what happened.

Do I have to give the other driver's insurer a recorded statement?

Usually not. You can ask to provide information in writing. Your own insurer is different, because your policy generally requires you to cooperate.

Can I choose my own repair shop?

In most states, yes. The insurer may recommend a network shop, but you can usually pick where the car is repaired.

When should I settle an injury claim?

Generally after you finish treatment or your doctor says you have reached maximum medical improvement, so you know the full cost before signing a release.

What if the insurer stops responding?

Follow up in writing with the dates you have been waiting. If that does not work, you can file a complaint with your state insurance department.
