What to Do After a Car Accident in Illinois (Step-by-Step)
If you’ve just been in a crash, what you do in the next hours and days can protect your health — and can also make a major difference in the value and strength of your injury claim. Insurance companies often begin building a defense immediately, and many people unknowingly harm their case by delaying treatment, giving recorded statements, or signing documents too early.
This guide explains what to do after a car accident in Illinois, what to avoid, and how to protect your rights. If you’d like to speak with a lawyer, Parker & Parker offers free consultations and there is no fee unless we win.
Step 1: Safety First (Minutes After the Crash)
- Check for injuries and call 911 if anyone may be hurt.
- Move to safety if vehicles are in traffic and can be moved.
- Do not leave the scene unless safety requires it.
- Stay calm and avoid admitting fault (even “I’m sorry” can be used against you).
Step 2: Call Police & Document the Crash
Whenever possible, call law enforcement so a report is created. A crash report can become a key piece of evidence — especially in disputed liability cases like intersection crashes.
What to gather at the scene
- Driver’s license + insurance info
- Photos of all vehicles and damage
- Photos of the roadway, skid marks, and traffic signals
- Witness names and contact information
- Time, location, and weather conditions
Tip: Take more photos than you think you need. Evidence disappears quickly.
Step 3: Get Medical Care — Even If You Feel Fine
Many injury symptoms begin later. This is extremely common with whiplash, concussion symptoms, and back injuries. Insurance companies often argue: “If you didn’t go to the doctor immediately, you weren’t really hurt.” The safest approach is early evaluation and consistent follow-up.
Injuries commonly delayed after a crash
- Neck pain / whiplash
- Headaches or migraine symptoms
- Concussion symptoms (dizziness, nausea, cognitive fog)
- Back pain or sciatica symptoms
- Shoulder or knee pain from bracing at impact

Step 4: Protect Your Claim (Insurance Traps to Avoid)
Insurers are trained to reduce payouts. Many people weaken their case by giving statements too early or signing releases before they understand their injuries.
Common mistakes after a crash
- Giving a recorded statement to the other driver’s insurer
- Accepting a quick settlement before treatment is complete
- Signing a release that permanently closes your claim
- Posting on social media about injuries or recovery
- Gaps in treatment or inconsistent symptom reporting
Important: If you sign a release of liability, your claim may be closed forever — even if symptoms worsen. Read our warning on release of liability forms.

Step 5: Build Your Case File (Make It Easy to Prove Damages)
If you’re injured, you will likely need to prove not just medical bills — but also how the injury changed your life. Keep a simple case file so you don’t lose important details.
What to keep
- Crash report number and copy of report
- Medical bills, discharge papers, and referrals
- Prescription receipts and out-of-pocket costs
- Physical therapy records
- Proof of missed work (pay stubs, employer letter)
- A short pain and symptom journal (daily or weekly)

FAQs: What to Do After a Car Accident in Illinois
What should I do immediately after a car accident in Illinois?
Get to safety, call 911 if anyone may be injured, exchange information, document the scene, gather witnesses, and seek medical care promptly. Avoid recorded statements or signing releases before understanding your injuries and legal options.
Should I go to the doctor even if I feel fine?
Yes. Many injuries appear later. Early evaluation protects your health and prevents insurers from arguing that you weren’t injured.
Do I have to give a recorded statement?
You generally do not have to give a recorded statement to the other driver’s insurer. It can harm your claim. Speak with a lawyer first.
What if the insurer offers a quick settlement?
Be cautious. Quick offers are often made before the full extent of injuries is known. If you sign a release, your claim may be permanently closed even if symptoms worsen.
How long do I have to file a car accident claim in Illinois?
Many injury claims must be filed within two years, but some cases have different timelines. Speak with a lawyer early to preserve evidence and protect your rights.
