A car accident is stressful, disorienting, and often frightening. In the minutes and hours after a collision, the decisions you make can significantly affect your insurance claim, your legal rights, and your financial recovery. This guide walks you through exactly what to do — in order — if you are involved in a car accident in Illinois.
At the Scene: The First 15 Minutes
1. Stop and Check for Injuries
Illinois law requires you to stop at the scene of any accident involving injury, death, or property damage. Leaving the scene of an accident is a criminal offense — even if the accident was not your fault.
Check yourself and your passengers for injuries first. If anyone is hurt, call 911 immediately. Do not attempt to move injured people unless there is an immediate danger such as fire.
2. Move to Safety
If the vehicles are drivable and the accident is minor, move them to the shoulder or a nearby parking lot to avoid blocking traffic. Turn on your hazard lights. If you cannot move the vehicle, stay inside with your seatbelt on until help arrives — standing on the roadway is one of the most dangerous things you can do after an accident.
3. Call the Police
In Illinois, you must report any accident that involves injury, death, or property damage over $1,500 to law enforcement. In practice, you should call the police for almost every accident, because:
- A police report creates an official record of what happened
- The other driver’s story may change later — the police report locks in their statements
- Many insurance companies require a police report to process a claim
- If the other driver was at fault, the report documents that
When officers arrive, give them your account of what happened. Stick to the facts. Do not speculate about who was at fault or say things like “I’m sorry” or “I didn’t see you.” These statements can be used against you later.
4. Exchange Information
Get the following from every other driver involved:
- Full name and contact information
- Driver’s license number and state
- Insurance company and policy number
- Vehicle make, model, year, and color
- License plate number
If there were witnesses, get their names and phone numbers as well. Witness accounts can be invaluable if there is a dispute about what happened.
5. Document Everything
Use your phone to take photos and video of:
- All vehicles involved, from multiple angles
- Damage to each vehicle (close-ups and wide shots)
- The overall accident scene, including road conditions, traffic signals, and signage
- Skid marks, debris, or anything that shows what happened
- Your injuries, if visible
- The other driver’s license plate, insurance card, and driver’s license
This documentation is powerful evidence for your insurance claim. Insurance adjusters rely heavily on photos to assess damage and determine fault.
After the Scene: The First 24–48 Hours
6. Seek Medical Attention
Even if you feel fine, see a doctor within 24 hours. Some injuries — particularly whiplash, concussions, and soft tissue damage — do not show symptoms immediately. Adrenaline can mask pain for hours or even days.
Getting checked out early matters for two reasons:
- Health: Early treatment prevents minor injuries from becoming serious
- Insurance: Medical records linking your injuries to the accident are essential for your claim. If you wait weeks to see a doctor, the insurance company may argue your injuries were caused by something else
7. Notify Your Insurance Company
Report the accident to your insurance company as soon as possible — ideally the same day. Most policies require “prompt notice” of any accident. Delaying the report can complicate your claim or, in extreme cases, give the insurer grounds to deny it.
When you call, have ready:
- The police report number
- The other driver’s insurance information
- Your photos and documentation
- A written account of what happened (write this while your memory is fresh)
Your insurance company will assign a claims adjuster to your case. The adjuster will investigate the accident, assess damage, and determine how much the insurer will pay.
8. Do Not Give a Recorded Statement to the Other Driver’s Insurer
The other driver’s insurance company may call you and ask for a recorded statement. You are not required to provide one, and in most cases, you should not. Their adjuster’s job is to minimize what their company pays — not to help you. Anything you say in that recorded statement can be used to reduce or deny your claim.
Politely tell them to contact your insurance company directly. If you sustained injuries, consider consulting with an attorney before speaking with the other insurer at all.
Understanding How Illinois Auto Insurance Claims Work
Illinois Is an At-Fault State
Illinois uses a fault-based system for auto accidents. This means the driver who caused the accident is responsible for the other party’s damages. You have three options for pursuing compensation:
- File a claim with your own insurer (if you have collision coverage) and let them pursue reimbursement from the at-fault driver’s insurer through subrogation
- File a third-party claim directly with the at-fault driver’s insurance company
- File a lawsuit against the at-fault driver (typically for serious injuries or large damages)
Modified Comparative Fault
Illinois follows a modified comparative negligence rule. You can recover damages as long as you are less than 50% at fault for the accident. However, your compensation is reduced by your percentage of fault. For example, if you are 20% at fault and your damages are $10,000, you would receive $8,000.
If you are 50% or more at fault, you cannot recover anything from the other driver. This is why the police report and your documentation are so important — they help establish fault percentages.
Statute of Limitations
In Illinois, you have two years from the date of the accident to file a personal injury lawsuit and five years for property damage. If you miss these deadlines, you lose the right to sue. For insurance claims, there is no statutory deadline, but most policies require “prompt” or “timely” reporting.
What Your Auto Insurance Covers After an Accident
The coverage you have determines what your insurer will pay for. Here is how the main coverages apply:
- Liability coverage: Pays for the other driver’s damages if you are at fault. This is the only coverage Illinois requires.
- Collision coverage: Pays to repair or replace your vehicle after an accident, regardless of fault. You pay the deductible first.
- Uninsured/underinsured motorist coverage: Pays for your damages if the at-fault driver has no insurance or not enough insurance. About 14% of Illinois drivers are uninsured.
- Medical payments (MedPay): Pays your medical bills regardless of fault, up to your coverage limit. Typically $5,000 to $25,000.
- Rental reimbursement: Pays for a rental car while your vehicle is being repaired.
If you only carry the minimum liability coverage Illinois requires (25/50/20), you have no collision, MedPay, or rental coverage for yourself. This is one of the biggest reasons we recommend coverage well above the state minimums.
Common Mistakes to Avoid
- Admitting fault at the scene. Even saying “I’m sorry” can be interpreted as an admission. Let the police and insurance companies determine fault.
- Not calling the police for “minor” accidents. Damage is often more extensive than it appears. A bumper that looks like a $500 fix can easily cost $3,000 once the repair shop gets behind it.
- Accepting a quick settlement. The other driver’s insurer may offer you a fast payout. These initial offers are almost always too low, especially if you have not yet discovered the full extent of your injuries.
- Posting about the accident on social media. Insurance companies routinely check social media. A photo of you looking healthy at a party can be used to challenge your injury claim.
- Not getting a rental car. If you have rental reimbursement coverage, use it. You are paying for it.
- Skipping the follow-up doctor visit. If your doctor recommends follow-up care, go. Gaps in your medical treatment weaken your claim.

The Bottom Line
The most important thing you can do after a car accident is stay calm and follow the steps in order. Document everything, report promptly, and do not make statements that could be used against you.
