An Illinois car accident can turn a normal commute into one of the most stressful moments of your day. One second you’re driving to work or heading home, and the next you’re standing on the side of the road with a damaged vehicle, a stranger, and a long list of questions. Your hands are shaking, your neck feels stiff, and you’re trying to figure out whether you should call the police, take photos, exchange insurance information, or seek medical attention first.
Knowing what to do after a car accident in Illinois can affect both your health and any future insurance claim or legal case. These steps after a car accident in Illinois can help you avoid common mistakes and make sure important evidence and information are preserved. Taking the right steps helps protect your safety, preserve important evidence, and comply with Illinois law.
The First 10 Minutes Matter Most
Before anything else, check on yourself and your passengers. If you can move safely, get out of traffic. Illinois law requires drivers involved in a crash to stop at or near the scene and remain there long enough to exchange the required information and provide reasonable assistance if anyone is injured. Crashes involving injury or death are governed by 625 ILCS 5/11-401, while property-damage-only crashes are covered by 625 ILCS 5/11-402. Leaving the scene before meeting these legal obligations can result in serious criminal penalties.
Illinois law also requires drivers involved in a crash to exchange their names, addresses, vehicle registration information, and insurance information with the other parties. If someone is injured, drivers must provide reasonable assistance, including arranging or obtaining medical transportation when necessary. Failing to exchange the required information or provide reasonable assistance can create additional legal consequences beyond the accident itself under 625 ILCS 5/11-403.
Once you’re safe:
- Turn on your hazard lights.
- Move to the shoulder or a nearby parking lot if your vehicle is drivable and it is safe to do so.
- Check yourself and your passengers for injuries.
- Call 911 if anyone is hurt, no matter how minor the injury may seem.
Do You Need to Call the Police?
Illinois no longer requires drivers to file a written crash report with the state after an accident, following changes made by Public Act 102-0560 in 2021. However, that does not mean you can skip notifying law enforcement. Under 625 ILCS 5/11-407, drivers must give immediate notice to the appropriate local law enforcement agency, usually through the quickest available means of communication, whenever a crash results in injury, death, or property damage exceeding the statutory reporting threshold. In practice, many drivers satisfy this requirement by calling 911.
If an officer investigates the crash, they will prepare an official crash report, which is submitted to the Illinois Department of Transportation according to state requirements.. If officers do not respond to the scene, report the crash to the appropriate law enforcement agency as soon as reasonably possible. For injury or fatal crashes, 625 ILCS 5/11-407 requires prompt notification, so it is important not to delay reporting the collision.
Skipping this step is not a minor technicality. Leaving the scene of a property-damage-only crash can result in criminal penalties under Illinois law, while leaving the scene of a crash involving injury or death can lead to more serious felony charges depending on the circumstances.
Gather Evidence While You Still Can
Memories fade fast, and skid marks don’t stay on the pavement forever. While you’re still at the scene, or as soon as it’s safe:
- Photograph both vehicles from multiple angles, including license plates and damage
- Photograph the road, traffic signals, skid marks, and weather conditions
- Get the other driver’s name, phone number, insurance company, and policy number
- Write down the badge number of any responding officer and ask for the crash report number
- Get contact information from anyone who saw what happened
This information often becomes the backbone of an insurance claim months down the road, so it’s worth the extra five minutes even when you’re rattled.
Preserve Digital Evidence
Evidence from a crash can disappear quickly. Before repairing your vehicle, replacing your phone, or deleting files, preserve any evidence related to the accident. Your insurer may need to inspect vehicle damage, and digital evidence may become important if fault or damages are disputed. Dashcam footage, cellphone photos, GPS records, text messages, and vehicle data may help show what happened. Backing up this information early can help prevent important evidence from being lost, overwritten, or unavailable later.
Get Checked Out, Even If You Feel Fine
Adrenaline is a convincing liar. Soft tissue injuries, concussions, and whiplash frequently do not announce themselves until a day or two later. Seeking medical attention as soon as possible is often one of the smartest steps after a crash. Prompt treatment protects your health and creates medical records that can help connect your injuries to the collision if you later pursue an insurance claim or lawsuit. Waiting several days or longer to seek treatment may give an insurance company an opportunity to argue that your injuries were unrelated to the accident or were not as serious as claimed.
Report the Crash to Your Insurance Company
Illinois law does not establish a deadline for notifying your own insurance company, but most auto insurance policies require prompt notice. Review your policy and notify your insurer as soon as reasonably possible after the crash. When you report the accident, provide the basic facts, such as the date, location, and the other driver’s information, but avoid speculating about who was at fault.
Your insurance company may also ask you to provide a recorded statement about the accident. Be truthful, but avoid guessing about details you do not remember or making conclusions about fault before the investigation is complete. Liability is determined based on the available evidence, and unnecessary or inaccurate statements could complicate your claim later.
Watch What You Say
Illinois follows a modified comparative negligence rule under 735 ILCS 5/2-1116. That means your compensation can be reduced by your percentage of fault, and if you’re found more than 50 percent responsible, you may be barred from recovering damages.
Statements made at the scene may later be considered alongside other evidence during an insurance claim or lawsuit. Stick to the facts when speaking with police, the other driver, or insurance representatives, and avoid guessing about what happened or accepting blame before the investigation is complete. If you have questions about your legal rights, discuss the details of the accident with your attorney rather than at the scene.

Frequently Asked Questions
Q: Do I call police for a minor accident in Illinois?
Not always. Illinois law generally requires drivers to notify law enforcement when a crash involves injury, death, or property damage that meets the reporting threshold under state law. If the accident is minor, no one is injured, and reporting is not required, you may not need to call police. Even when a report is not required, documenting the crash and exchanging information with the other driver is still important.
Q: What happens if I forget to exchange insurance information?
If you did not exchange information at the scene, try to obtain the other driver’s contact and insurance details as soon as possible. If police responded, the crash report may contain information about the involved drivers. Illinois law requires drivers involved in qualifying crashes to provide identifying, vehicle, and insurance information to the other parties upon request.
Q: How long do I have to file a personal injury lawsuit after a car accident in Illinois?
In most cases, you have two years from the date of the accident to file a personal injury lawsuit under 735 ILCS 5/13-202. Property damage claims may have a different deadline. Because exceptions can apply, it is important not to wait too long before exploring your legal options.
Q: What if the other driver leaves before police arrive?
Write down as much information as possible, including the vehicle description, license plate number, location, and time of the crash. Report the incident to law enforcement as soon as possible, as it may be investigated as a hit-and-run crash.
Q: Can I still recover damages if I was partly at fault?
Possibly. Illinois follows a modified comparative negligence rule under 735 ILCS 5/2-1116. You may recover damages if you are not more than 50% responsible for the accident, but your compensation can be reduced by your percentage of fault. If you are found more than 50% at fault, you generally cannot recover damages.
