Car Accident Insurance Claims in the US: Step-by-Step Filing, At-Fault vs No-Fault States, and How Your Rates Change

Updated October 7, 2026. Educational content for US drivers, not legal or insurance advice. Claim rules, reporting deadlines, and fault laws vary by state and by policy, so check your own policy and your state insurance department for specifics.

A crash, even a small one, scrambles your thinking. Your heart is racing, traffic is backing up, and the other driver may be apologizing or arguing. The choices you make in the next hour and the next few days, though, can decide how fast your car gets fixed, who pays for it, and whether your premium jumps for years.

This guide walks through what to do at the scene, how to open a claim, how fault works in different states, what the adjuster actually does, and how an accident can affect your rates.

Step 1: At the scene, safety and documentation first

• Check for injuries and call 911 if anyone is hurt. Medical help comes before paperwork.
• Move to safety if you can. If the cars are drivable and no one is hurt, many states expect you to clear the travel lanes. Turn on your hazard lights.
• Call the police when required. Most states require a report when there are injuries, a death, or property damage above a set dollar amount. Even for minor crashes, a police report gives the insurers a neutral record.
• Exchange information. Get the other driver's name, phone number, driver's license number, plate number, vehicle make and model, and insurance company and policy number. A photo of their insurance card is fastest.
• Take lots of photos. Capture both cars from several angles, the damage up close, the road, traffic signs, skid marks, weather, and the overall scene. Note the time and exact location.
• Talk to witnesses. Ask for names and phone numbers. Independent witnesses can settle a fault dispute.
• Don't argue or admit fault. Be polite and factual. Fault is determined later from evidence and state law, not from what someone said in the moment.

Step 2: Notify your insurer quickly

Nearly every auto policy requires you to report an accident "promptly." Some insurers set specific time limits, and late reporting can complicate or even jeopardize coverage. You can usually start a claim through the insurer's app, website, or claims phone line, often 24/7.

Have ready: your policy number, the date, time and location, a short description of what happened, the other driver's details, the police report number if there is one, and your photos. Stick to facts you know. If you aren't sure about speeds or distances, say so instead of guessing.

Should you report a crash even if you plan to pay yourself? Read your policy. Many require you to report any accident, and if the other driver later claims injuries or damage, your insurer will want to have heard about it from you first.

Step 3: Know whether you live in an at-fault or a no-fault state

How a claim gets paid depends heavily on your state's system.

At-fault (tort) states

Most states use an at-fault system. The driver who caused the crash, through their liability coverage, pays for the other people's injuries and property damage. If the other driver hit you, you have options:

• File a third-party claim with the other driver's insurer. You pay no deductible, but you are dealing with a company that represents the other side, and it can be slower.
• File with your own insurer under your collision coverage. You pay your deductible up front, your insurer fixes your car faster, and then it tries to recover the money from the at-fault driver's insurer through a process called subrogation. If it wins, you may get your deductible back.

Many states also use comparative negligence, which means fault can be split, for example 70/30, and payments are reduced by your share. A few states still use stricter rules that can bar recovery if you were even partly at fault.

No-fault states

About a dozen states, including Florida, Michigan, New York, New Jersey, and Pennsylvania, use a no-fault system for injuries. Your own personal injury protection (PIP) pays your medical bills and some lost wages, no matter who caused the crash. Suing the other driver for pain and suffering is limited unless injuries pass a state threshold. Important: no-fault rules usually apply to injuries, not vehicle damage. Car repairs are still generally handled based on fault.

Step 4: Which part of your policy pays for what

Coverage	What it typically pays
Liability (bodily injury and property damage)	Other people's injuries and property when you are at fault
Collision	Damage to your car from a crash, regardless of fault, minus your deductible
Comprehensive	Non-crash damage such as theft, hail, flood, fire, or hitting a deer
Uninsured/underinsured motorist (UM/UIM)	Your injuries, and in some states car damage, when the at-fault driver has no or too little insurance, including many hit-and-runs
PIP or medical payments (MedPay)	Medical bills for you and your passengers, regardless of fault
Rental reimbursement	A rental car while yours is in the shop, up to daily and total limits

If you only carry liability coverage and the crash was your fault, your own car's damage is generally not covered by your policy.

Step 5: The adjuster, the estimate, and the repair shop

After you file, a claims adjuster is assigned. They review the police report, statements, and photos, decide fault on behalf of the insurer, and estimate the damage. The estimate might come from photos you upload in the app, a drive-in inspection site, or an appraiser who visits the shop.

• You can usually choose your repair shop. Insurers may recommend a network or "direct repair" shop and sometimes offer a repair guarantee there, but in many states they cannot require you to use a specific shop.
• Supplements are normal. Once a shop takes a bumper apart, it often finds hidden damage. The shop sends a supplemental estimate to the insurer for approval.
• Ask about parts. Estimates may specify aftermarket or used parts instead of original equipment manufacturer (OEM) parts. Your policy and state rules determine what you're entitled to, so ask before repairs start.
• Keep every receipt. Towing, rental cars, and medical visits can all be part of the claim.

If your car is a total loss

When repair costs come close to or exceed the car's value, the insurer may declare it a total loss. You are paid the car's actual cash value (ACV), its market value just before the crash, minus your deductible. If you owe more on your loan or lease than the ACV, the difference is your responsibility unless you carry gap insurance. You can push back on a low valuation by sending listings for comparable vehicles in your area, along with records of recent upgrades, new tires, or low mileage.

How an accident can affect your rates

An at-fault accident usually raises your premium at renewal, and the surcharge commonly sticks for about three to five years, depending on the insurer and state. Not-at-fault accidents generally have less impact, and some states limit surcharges when you weren't to blame. Claims are also recorded in industry databases such as your CLUE report, which other insurers check when quoting you.

Ways to soften the hit:

• Check for accident forgiveness. Some policies waive the surcharge for a first accident, either as a perk for long-time customers or as a paid add-on.
• Shop around at renewal. Insurers weigh accidents differently, so a quote comparison after a surcharge can pay off.
• Consider a defensive driving course. Some states and insurers offer discounts for completing an approved course.
• Revisit your deductible. A higher collision deductible lowers your premium, as long as you can cover it from savings.

When it might make sense not to file

For a small, single-car scrape where the repair costs little more than your deductible, paying out of pocket can keep a claim off your record. That calculation changes fast if anyone else is involved, if there is any chance of injury, or if your policy requires reporting every accident. When another driver or property is involved, report it to your insurer even if you hope not to use your coverage.

Red flags and when to get help

• The other driver asks to "keep insurance out of it" and pay cash, then stops responding.
• Someone pressures you to sign a release or accept a quick settlement before you know the full extent of your injuries.
• Your insurer denies the claim without a clear explanation, or the claim stalls for weeks.

If you were seriously hurt, talking with a personal injury attorney before accepting a settlement is common. For disputes with your own insurer, you can ask for the decision in writing, use the insurer's appeal process, and file a complaint with your state insurance department if needed.

Quick checklist

1. Get safe, call 911 if anyone is hurt, and call police when required.
2. Exchange information and photograph everything.
3. Report the accident to your insurer promptly.
4. Know your state's fault system and which coverage applies.
5. Pick your repair shop and keep all receipts.
6. Challenge low total-loss values with comparable listings.
7. Shop your policy at renewal if your rate jumps.

The bottom line

Car accident claims go smoothest when you document the scene well, report quickly, and understand which coverage is supposed to pay. Knowing whether your state is at-fault or no-fault, how subrogation can return your deductible, and how long a surcharge may last helps you make calmer, cheaper decisions. Before your next renewal, review your liability limits, UM/UIM, rental reimbursement, and deductibles, so the policy you have is the one you'd want on the worst day of the year.
