What to Do After a Car Accident in Illinois: A Step-by-Step Guide

After a car accident in Illinois, do these things in order: get to safety and check for injuries, call 911 so police create a report, and get medical help for anyone who needs it. At the scene, take photos, exchange information with the other driver, and get names and numbers for any witnesses. See a doctor even if you feel fine — some injuries show up days later. Report the crash to your own insurer, but be careful about what you say to the other driver's insurance company. And keep the deadline in mind: in Illinois you generally have two years from the date of injury to file a personal injury claim.
First: get to safety and check for injuries
Your health comes first. Before anything else, check yourself and your passengers for injuries. If anyone is hurt, that changes the order of everything below — help them and wait for paramedics.
If the cars are drivable and it's safe, move them out of traffic to the shoulder or a nearby lot. If they aren't, turn on your hazard lights and stay put. On a busy Chicago road, staying inside the vehicle with your seatbelt on is often safer than standing in traffic. Take a breath. The next few steps go better when you're not rushing.
Call 911 and get a police report
Call 911. In Illinois, you're required to report a crash that involves injury, death, or property damage over a certain amount, and calling the police is the simplest way to meet that duty.
When officers arrive, tell them what happened plainly and honestly. Stick to the facts. This isn't the moment to guess about fault or apologize out of politeness — a casual "I'm sorry" can be twisted later. Ask how to get a copy of the police report and write down the responding officer's name and badge number.
That report matters. It's an early, neutral record of the scene, and insurers and courts lean on it heavily.
Document the scene
If you're able to, gather evidence before you leave. Memories fade and cars get towed. Photos don't.
Try to capture:
- The vehicles — damage on both cars, from several angles.
- The scene — the whole intersection or stretch of road, skid marks, traffic signals, and any debris.
- Conditions — weather, lighting, and anything blocking a clear view.
- The other driver's information — name, phone number, address, driver's license, license plate, and insurance details.
- Witnesses — names and phone numbers for anyone who saw it happen. A neutral witness can be worth a lot.
If you can't do this safely or you're too hurt, don't force it. Your health outranks any photo.
Get medical care — even if you feel okay
This is the step people skip, and it's the one that comes back to bite them. Adrenaline hides pain. Injuries like whiplash, concussions, and internal damage often don't announce themselves until a day or two later.
Get checked out, either at the scene, at an ER, or with your own doctor soon after. Two reasons. First, for your health — some injuries get worse when they go untreated. Second, for any claim you might bring. When you wait weeks to see a doctor, an insurance company will argue you weren't really hurt, or that something else caused it. A prompt medical record connects your injuries to the crash.
Follow the treatment plan you're given and keep every record: bills, discharge papers, prescriptions, and notes about how the injury affects your daily life.
Report the crash — and be careful with insurers
Tell your own insurance company about the accident. Most policies require prompt notice, and cooperating with your own insurer is part of the deal.
The other driver's insurance company is a different story. An adjuster may call quickly, sound friendly, and ask for a recorded statement or a quick settlement. Be cautious.
A few things to keep in mind:
- You are not required to give the other driver's insurer a recorded statement.
- Don't guess about fault or the extent of your injuries. "I feel fine" on day one can be used against you on day thirty.
- Early settlement offers are often low. Once you accept, you usually can't reopen it — even if your injuries turn out to be worse than they looked.
- Stick to the basic facts: when and where it happened, and the vehicles involved.
There's a legal reason to be careful about fault, too. Illinois uses modified comparative negligence. You can recover if you're 50% or less at fault, but your compensation is reduced by your share. If you're found more than 50% at fault, you recover nothing. Insurers know this, which is why they push to pin blame on you early.
Know the deadline — and when to call a lawyer
Illinois gives you a limited window to act. For most personal injury claims, the statute of limitations is two years from the date of injury. Miss it, and you can lose the right to file, no matter how strong your case is.
Some situations are different. Claims against a government body (a city bus, say) can have much shorter deadlines — often one year. Two years may feel like plenty, but building a solid case takes time, and evidence disappears. It's better to understand your options early than to scramble later.
You don't need a lawyer for every fender-bender. But it's worth a conversation when there are real injuries, when fault is disputed, when the insurance company is dragging its feet or lowballing you, or when a government vehicle or a commercial truck is involved. A good lawyer handles the insurers, gathers the evidence, and works out what your claim is actually worth — so you can focus on getting better. Our team handles Illinois car accident cases on a contingency basis, which means no upfront cost and no fee unless we win.
Frequently asked questions
Should I call the police for a minor accident?
Yes, in most cases. A police report is a neutral record of what happened, and Illinois requires reporting crashes that involve injury or significant property damage. Even a minor-looking crash can involve injuries that surface later, so having an official report protects you.
What should I not say to the other driver's insurance company?
Don't admit fault, don't guess about your injuries, and don't agree to a recorded statement without advice. Avoid saying "I'm fine" — injuries can appear days later. Stick to the basic facts and be cautious about early settlement offers, which are often lower than your claim is worth.
How long do I have to file a car accident claim in Illinois?
For most personal injury claims, you generally have two years from the date of injury. Claims against a government entity often have a much shorter window, sometimes one year. Because deadlines vary and evidence fades, it's smart to check your specific situation early.
What if the accident was partly my fault?
You can still recover in Illinois as long as you're 50% or less at fault, under the state's modified comparative negligence rule. Your compensation is reduced by your percentage of fault. If you're found more than 50% at fault, you can't recover — which is why insurers work hard to shift blame onto you.
Do I have to pay a lawyer upfront?
No. Personal injury cases are typically handled on a contingency fee basis, meaning there's no upfront cost and no fee unless the firm recovers money for you. That lets you get help regardless of your financial situation.
