To file an insurance claim after a car accident, you need to do four things well: make the scene safe and document it, notify the right insurance company quickly, cooperate with the adjuster without undermining your own position, and check the settlement offer against your actual losses before you accept it. Claims that go wrong usually do so because of missing evidence, a careless recorded statement or a missed deadline.
This guide walks through the process in order, explains whose insurer pays in different situations, and sets out when it makes sense to consult an attorney.
It is written for drivers in the United States and is general information, not legal advice. Laws, deadlines and fault rules vary by state.
What Should You Do at the Scene?
What you do in the first thirty minutes shapes the whole claim.
- Check for injuries and call 911 if anyone is hurt or vehicles are blocking traffic. Move to a safe spot if you can and switch on hazard lights.
- Call the police. Many states require a report when there are injuries or damage above a set amount, and insurers rely heavily on police reports. Note the report number.
- Exchange information: names, phone numbers, driver’s license numbers, license plates, insurers and policy numbers. Photograph the other driver’s insurance card and license rather than copying by hand.
- Photograph everything: all vehicles from several angles, close-ups of damage, the wider scene, skid marks, debris, traffic signs, weather and road conditions, and any visible injuries.
- Collect witness details. Independent witnesses are often decisive when drivers disagree.
- Do not admit fault or apologize in a way that sounds like it. Describe facts to the police; leave fault to the investigation.
- Get medical attention. Some injuries, including whiplash and concussion, show up hours or days later. Prompt medical records link the injury to the accident.
Whose Insurance Company Do You File With?
You generally have two routes. A first-party claim is made with your own insurer under your own coverage. A third-party claim is made against the at-fault driver’s liability insurance. Which one applies depends on fault, your coverage and your state.
| Situation | Coverage that responds | Where to file |
|---|---|---|
| Other driver clearly at fault, damage to your car | Their property damage liability, or your collision cover | Their insurer, or yours if you want faster repairs (your insurer then recovers from theirs) |
| You were at fault | Your collision cover for your car; your liability cover for the other party | Your insurer |
| Injuries in a no-fault state | Your personal injury protection (PIP) | Your insurer first, regardless of fault |
| Injuries in an at-fault (tort) state | At-fault driver’s bodily injury liability; your MedPay or health insurance in the meantime | Their insurer, with your own as backup |
| Hit-and-run or uninsured driver | Your uninsured motorist (UM) cover and collision | Your insurer; a police report is usually required |
| At-fault driver’s limits too low | Your underinsured motorist (UIM) cover | Your insurer, after the other policy pays out |
| Theft, hail, flood, animal strike | Your comprehensive cover | Your insurer |
About a dozen states, including Michigan, New York and New Jersey, use no-fault systems in which your own PIP pays medical bills and some lost income up to its limit, and lawsuits against the other driver are restricted unless injuries meet a legal threshold. Even if you plan to claim from the other driver’s insurer, notify your own company promptly. Almost every policy requires it, and it protects you if the other insurer delays or denies.
How to File the Claim: Step by Step
- Report the accident to your insurer as soon as possible, ideally within 24 hours. Use the app, website or claims phone line. Policies require “prompt” notice, and late reporting is a common ground for denial.
- Give the basic facts: date, time, location, vehicles and people involved, police report number and a short factual description. You will receive a claim number; use it on all correspondence.
- Open the third-party claim, if applicable, by contacting the other driver’s insurer with their policy number. You are not obliged to give them a recorded statement, and it is reasonable to decline until you have your facts and, for injury claims, legal advice.
- Submit your evidence: photos, witness details, the police report and any dashcam footage.
- Arrange the damage inspection. The adjuster may inspect in person, send you to an approved shop or ask for photos through an app.
- Get your own repair estimate. You generally have the right to choose your repair shop. An independent estimate is a useful check on the insurer’s figure.
- Ask about a rental car. It is covered if you bought rental reimbursement, or by the at-fault driver’s insurer once it accepts liability.
- Keep a claim file: a log of every call with names and dates, copies of emails, medical bills, pay stubs showing lost income, towing and storage receipts, and out-of-pocket costs.
- Review the settlement offer against your documents before you sign anything. A release is final.
What Happens After You File?
The investigation
An adjuster reviews the statements, the police report and the damage to decide who was at fault and what the policy owes. In many states fault can be shared under comparative negligence rules, which reduces your payout by your percentage of blame.
Repairs or total loss
If the repair cost approaches or exceeds the car’s value, under your state’s threshold, the insurer declares a total loss and pays the actual cash value just before the crash, minus your deductible on a first-party claim. Check the valuation report: make sure the trim level, mileage, options and condition are correct and that the comparable vehicles are genuinely comparable and local.
If you still owe more on your loan or lease than the car is worth, the insurer’s payment will not clear the balance unless you have gap coverage. It is worth understanding before you finance a vehicle, as we explain in our guide to auto loans for first-time buyers.
Your deductible and subrogation
If you use your own collision cover for a crash that was not your fault, you pay your deductible up front. Your insurer then pursues the at-fault insurer, a process called subrogation, and refunds your deductible in full or in part if it succeeds. In some states you can also claim diminished value, the loss in resale value a repaired car suffers, from the at-fault driver’s insurer.
Mistakes That Reduce or Sink a Claim
- Leaving the scene without a police report or photos.
- Admitting fault, or speculating about speed and distances in a recorded statement.
- Delaying medical treatment, then claiming injury weeks later.
- Posting about the accident on social media.
- Accepting the first injury settlement offer before you know the full cost of treatment.
- Signing a broad medical authorization that gives the other insurer access to your entire medical history.
- Missing the statute of limitations. The deadline to sue is commonly two or three years but is as short as one year in a few states, and claims against government bodies often require notice within months.
When Should You Consult an Attorney?
You do not need a lawyer for a straightforward fender-bender with no injuries. Hiring one for a small property-damage claim rarely makes financial sense. Consider a consultation, which most personal injury attorneys offer free, when any of the following apply:
- anyone suffered a significant injury, needed hospital treatment, faces lasting impairment or died;
- fault is disputed or you are being blamed unfairly;
- the insurer denies the claim, stops responding, delays without explanation or makes an offer far below your documented losses;
- the at-fault driver was uninsured or underinsured and you are claiming against your own UM or UIM cover;
- several vehicles, a commercial truck, a rideshare driver or a government vehicle were involved;
- you are asked to sign a release you do not fully understand;
- you are being sued, in which case tell your own insurer immediately, because your liability cover normally includes a defense lawyer at no cost to you.
Personal injury attorneys usually work on a contingency fee, commonly around one third of the recovery and often more if the case goes to trial, plus case expenses. Ask for the fee agreement in writing, and ask how costs are handled if the case is lost. Verify that the attorney is licensed with your state bar, and be cautious about anyone who contacts you unsolicited after an accident.
What If Your Claim Is Denied or Underpaid?
- Ask for the denial or valuation in writing, with the policy language relied on.
- Respond with evidence: independent repair estimates, comparable vehicle listings, medical records or witness statements.
- Escalate to a claims supervisor or the insurer’s internal appeals process.
- Use the appraisal clause in your own policy for disputes about the amount of vehicle damage; each side appoints an appraiser and an umpire resolves differences.
- File a complaint with your state insurance department, which you can find through the National Association of Insurance Commissioners or USA.gov. Regulators cannot order a specific payout in every case, but insurers take their inquiries seriously.
- Consider small claims court or an attorney if the gap remains large.
Will Filing a Claim Raise Your Premium?
An at-fault claim usually leads to a surcharge lasting three to five years, unless you have accident forgiveness. A not-at-fault claim often does not, though practices vary by state and insurer. If the damage to your own car is only slightly above your deductible and no one else is involved, paying out of pocket may be cheaper in the long run, but you should still notify your insurer of any accident involving another party. If your renewal price jumps, compare the market; our overview of the top US car insurance providers is a starting point, and families with young drivers should also read our guide to the cheapest car insurance for teen drivers.
Frequently Asked Questions
How long do I have to file a car insurance claim?
Your policy requires prompt notice, so report within a day or two. Separate legal deadlines apply to lawsuits, commonly two to three years for injury depending on the state. Do not wait for either; evidence and memories fade quickly.
How long does a car accident claim take to settle?
Simple property-damage claims often settle within one to a few weeks. Injury claims take longer, because you should not settle until treatment is finished or your long-term outlook is clear.
Should I talk to the other driver’s insurance company?
You can give basic facts to open a property-damage claim. You are generally not required to give a recorded statement or discuss injuries, and if you were hurt it is sensible to get legal advice before doing so.
Can I file a claim without a police report?
Yes, but it is harder. Insurers can still investigate using photos, statements and damage patterns, and some states let you file a report after the fact. For hit-and-run and uninsured motorist claims, a police report is usually required.
Bottom Line
Document the scene, report promptly, keep every record and do not sign a release until the numbers match your losses. Handle simple property-damage claims yourself, and bring in a licensed attorney when there are serious injuries, disputed fault or an insurer that will not deal fairly. Handled methodically, filing an insurance claim after a car accident is a process you can control rather than one that happens to you.
