How Long a Car Accident Claim Takes From Start to Finish
The timeline depends on who is at fault and whether injuries are involved
A car accident claim typically takes between two weeks and several months to resolve, depending on the complexity of the accident and whether anyone was injured. If the accident is straightforward — both drivers agree on what happened, there are no injuries, and damage is minor — your claim may settle in two to four weeks. If liability is disputed, injuries are involved, or damage is extensive, expect three to six months or longer.
The timeline also depends on whether you are filing a claim with your own insurance company (called a first-party claim) or with the other driver's insurance (called a third-party claim). First-party claims usually move faster because your insurer has a financial incentive to settle quickly. Third-party claims depend on how responsive the other driver's insurance company is and how willing they are to accept liability.
Key Takeaways
- Report your accident to your insurance company within 24 to 48 hours — most policies require prompt notice, and delays can affect your claim.
- The other driver's insurance company has 15 to 30 days to acknowledge your claim and begin investigating, though this varies by state.
- If injuries are involved, the claim will not settle until medical treatment is complete, which can take months or years.
- You can request a settlement offer once the other insurer has finished investigating, but accepting it ends your right to pursue further compensation.
- If you and the insurer cannot agree on the settlement amount, you may pursue a lawsuit, which adds six months to several years to the process.
The first 48 hours: reporting and initial documentation
Report the accident to your insurance company as soon as possible, ideally within 24 hours. Most insurance policies require prompt notice, and waiting too long can give your insurer a reason to deny your claim. When you call, have the other driver's name, phone number, address, insurance company, and policy number ready. Also have the accident location, date, time, and a brief description of what happened.
Your insurer will assign a claims adjuster to your case. This person will contact you to schedule an inspection of your vehicle and take your formal statement about the accident. Take photos of the damage to your car, the other vehicle, and the accident scene if you have not already. If there were witnesses, write down their names and phone numbers — your adjuster will want to contact them.
Days 3 to 15: the investigation phase
Your insurance company will begin investigating the accident. If you filed a claim with the other driver's insurance instead of your own, that company has 15 to 30 days (depending on your state) to acknowledge receipt of your claim and start their investigation. During this time, the adjuster will review police reports, medical records if applicable, repair estimates, and witness statements.
If the accident is straightforward and liability is clear, the investigation may be complete within a week or two. If liability is disputed — for example, if both drivers claim the other ran a red light — the investigation will take longer. The adjuster may request additional statements, review traffic camera footage, or consult accident reconstruction experts.
Weeks 2 to 4: repair estimates and liability information
Your insurer will obtain repair estimates for your vehicle. You may be asked to get your own estimate from a repair shop of your choice. If the estimates differ significantly, the insurer may send their own appraiser to inspect the vehicle. Once repair costs are agreed upon, the insurer will either authorize repairs or issue you a check for the damage.
During this phase, the insurer will also make a formal information about liability — whether the other driver was at fault, whether you were partially at fault, or whether liability is unclear. In states with comparative fault laws, you may still recover damages even if you were partially at fault, though your recovery will be reduced by your percentage of fault. The insurer will communicate this information to you in writing.
Weeks 4 to 8: settlement negotiation (if no injuries)
If no one was injured in the accident, the claim can often move to settlement within four to eight weeks. Once the insurer has determined liability and agreed on repair costs, they will issue a settlement offer. This offer covers the cost of repairs, rental car expenses while your vehicle is being fixed, and any other covered losses.
You have the right to negotiate the settlement amount if you believe it does not fully cover your losses. If you disagree with the repair estimate, you can request that the insurer use a different repair shop or obtain an independent appraisal. Once you accept the settlement offer and sign a release, the claim is closed and you cannot pursue further compensation from that insurer.
Months 2 to 6 or longer: claims involving injuries
If anyone was injured in the accident, the timeline extends significantly. The claim will not settle until medical treatment is complete, which can take weeks, months, or even years depending on the severity of the injury. Your insurer will request medical records and bills from all healthcare providers involved in your treatment.
Once treatment is complete, you or your attorney will submit a demand letter to the insurer outlining all damages: medical bills, lost wages, pain and suffering, and any other losses. The insurer will review this demand and make a counter-offer. Negotiation can take several weeks or months. If you and the insurer cannot reach agreement, you may file a lawsuit, which extends the timeline considerably.
What happens if you disagree with the settlement offer
If the insurer's settlement offer does not cover your losses, you have several options. You can request a detailed breakdown of how they calculated the offer and provide evidence that their calculation is incorrect. You can obtain your own repair estimate or medical evaluation and submit it to the insurer. You can also hire an attorney to negotiate on your behalf.
If negotiation does not work, you can file a lawsuit against the at-fault driver. This process typically takes six months to several years, depending on court schedules and case complexity. Before filing, understand that litigation is expensive — you will pay court fees and attorney fees — and the outcome is uncertain. Many cases settle during the lawsuit process rather than going to trial.
State-specific requirements that affect your timeline
South Carolina law requires insurance companies to acknowledge claims within 15 days and to begin investigating promptly. The state also has a statute of limitations of three years for property damage claims and three years for bodily injury claims, meaning you have that long to file a lawsuit if you choose to pursue one.
South Carolina is a fault-based insurance state, meaning the driver at fault is responsible for damages. If you are found partially at fault, your recovery is reduced by your percentage of fault. These rules affect how insurers investigate and settle claims, but they do not change the basic timeline — most straightforward claims still settle within two to four weeks.
Frequently Asked Questions
How long do I have to report an accident to my insurance company?
Report it within 24 to 48 hours. Most insurance policies require prompt notice, and delaying beyond a few days can give your insurer grounds to deny your claim. If you are injured and unable to report immediately, contact your insurer as soon as you are able and explain the delay.
Can I settle my claim without going through insurance?
Yes. You can negotiate directly with the other driver and settle the claim privately. However, this is risky — you have no legal protection if the other driver fails to pay, and you may not discover hidden damage or injuries until after the settlement is final. Most people use insurance to protect themselves.
What if the other driver's insurance company denies liability?
If they deny that their driver was at fault, your claim will take longer to resolve. You may need to provide police reports, witness statements, or accident reconstruction evidence to prove liability. If you cannot reach agreement, you can file a lawsuit. Your own insurance company may also cover your damages under your uninsured or underinsured motorist coverage while the dispute is resolved.
Do I have to accept the first settlement offer?
No. You can negotiate, request additional documentation, or reject the offer entirely. However, once you sign a release accepting the settlement, you cannot pursue further compensation. Take time to review the offer and consider whether it covers all your losses before signing.
How much longer does a claim take if someone was injured?
Injury claims typically take two to six months longer than property-only claims because medical treatment must be complete before settlement. If the injury is serious or recovery is slow, the claim can take a year or more. The more severe the injury, the longer the timeline.
