After a Crash in Illinois — Official Resources
This is general information, not legal advice.
Illinois has a threshold that moves. Per the Illinois State Police, a driver must file a crash report if the crash caused death, bodily injury, or more than $1,500 in property damage when all drivers are insured — but if any driver is uninsured, the threshold drops to $500. If no police officer appears at the scene, you file with the Illinois State Police within 10 days. Note what changed: the old SR1B Illinois Motorist Report to IDOT is no longer required under Public Act 102-0560, though guides published this year still tell people to send it. Single-vehicle, property-damage-only crashes on an Interstate or U.S./Illinois Route can be self-reported online. Free help: ISBA IllinoisLawyerFinder at 800-922-8757 or 217-525-5297 ($25 initial consultation), and the Chicago Bar referral at 312-554-2001.
Illinois is the only state on this site where the reporting threshold depends on somebody else’s insurance — $1,500 normally, $500 if any driver involved turns out to be uninsured. It’s also a state where the paperwork changed and much of the internet didn’t notice. Both are in the first card. After it: getting the report, lawyer referrals, free legal help, and insurance complaints. The first-steps checklist covers saving your dashcam clip before the camera loops.
Report the crash — 10 days if no officer came
Per the Illinois State Police, each driver involved in an Illinois crash must file a report if the crash caused:
- Death or bodily injury, or
- More than $1,500 in property damage when all drivers are insured, or
- More than $500 in property damage if any driver does not have insurance
If a police officer does not appear at the scene, you file with the Illinois State Police within 10 days. Separately, under 625 ILCS 5/11-407, a crash causing injury or death must be reported to the nearest police department immediately when no officer is present.
What changed: the Illinois Department of Transportation states plainly that under Public Act 102-0560, a motorist involved in a crash no longer needs to complete the SR1B Illinois Motorist Report and send it to IDOT. Articles published this year still instruct drivers to file with IDOT within ten days. That form is not the requirement anymore — the State Police filing above is.
Filing it yourself
Illinois State Police offer two routes when nobody came out.
Online self-report, available when the crash was a single vehicle, property-damage-only, with no injuries to anyone, and occurred on an Interstate or a U.S. or Illinois Route. ISP publishes a tutorial walking through the form.
Desk report in person, for crashes on a Chicagoland freeway, filed within 10 days at the IDOT Park and Ride at I-55 and Route 30 in Joliet, or the Illinois Tollway Central Authority at 2700 Ogden in Downers Grove. Call (847) 294-4400 on arrival to request a trooper.
Get the crash report
Request the report from the agency that worked the scene — the municipal police department, the county sheriff, or the Illinois State Police. Under 625 ILCS 5/11-408, investigating officers must submit crash reports to IDOT within 10 days after the investigation, so allow a couple of weeks before assuming yours is missing.
IDOT is the statewide repository and uses the data for crash analysis and roadway safety design, but for a copy of your own report the responding agency is the faster route.
Hit-and-run
Call police immediately. In Illinois this is a criminal matter for the other driver — leaving the scene of a property-damage crash is a Class A misdemeanor, and leaving the scene of an injury crash is a felony under 625 ILCS 5/11-401.
There’s also a practical wrinkle unique to Illinois: an unidentified driver is functionally an uninsured one for reporting purposes, so assume the lower $500 threshold applies and report it. If no officer responds, the 10-day State Police filing is yours. Save your clip and note the time and location while they’re exact — on the Kennedy or the Eisenhower there may be traffic cameras, but the plate your dashcam caught is what gives investigators a starting point. Uninsured-motorist coverage on your own policy is the usual route to payment, and its hit-and-run notice window is often far shorter than the claim deadline.
Find a lawyer
The ISBA IllinoisLawyerFinder refers statewide — call 217-525-5297 weekdays 9 a.m. to 3 p.m., or 800-922-8757. The initial consultation runs $25. Participating lawyers must be registered with the Illinois Supreme Court’s Attorney Registration and Disciplinary Commission and carry professional liability insurance.
Two things the ISBA is explicit about, and they matter. Names are given out on a rotating basis — a referral is not an endorsement of expertise, so ask about the lawyer’s experience with crash claims at the first appointment. And the lawyer will not call you: you contact their office, and you must mention you came through the referral service to get the special rate.
In Chicago and Cook, DuPage, and Lake counties, the Chicago Bar Association also runs its own service at 312-554-2001.
Free legal help
The Clerk of the Circuit Court of Cook County maintains a current list of referral and reduced-cost options, which is useful because it’s kept by the court rather than by any single provider.
Two worth knowing from it: the Justice Entrepreneurs Project at (312) 546-3282 refers to lawyers offering lower-cost service, often at fixed fees with flexible representation; and the South Suburban Bar Association at (708) 239-8500 covers the southern suburbs and the Sixth Municipal District.

Insurance problems
The Illinois Department of Insurance regulates insurers in the state and takes consumer complaints about how claims are handled. You can reach its current complaint channels through the national directory of state insurance departments.
Uninsured when it happened? Note that your lack of coverage changes the reporting math for everyone involved — it pulls the threshold down to $500, which means a crash that would otherwise have been nobody’s paperwork now has to be reported. File it rather than hoping it passes unnoticed, and use the referral options above; Illinois caps that first consultation at $25, which is a low price for finding out where you actually stand.
