Where Your Crash Report Lives in Illinois
The agency that responded to your crash is the agency that holds the report. Each agency runs its own request channel: some use the LexisNexis BuyCrash portal, some run their own portals, and some only respond to FOIA.

The Free Path: FOIA Under 5 ILCS 140
Illinois has one of the more requestor-friendly FOIA statutes in the country. Five business days to respond, the first 50 pages free, fee waivers for “public interest” requests, and a binding-decision Public Access Counselor if an agency stalls. Here is the process that works for any Illinois agency.
Identify the responding agency
Check the “Investigated By” box on your motorist exchange card. If it says Illinois State Police, your request goes to ISP. If it says a city PD or county sheriff, it goes to that agency. State agencies and local agencies do not share crash-report databases.
Locate the FOIA officer
Every Illinois public body must designate a FOIA officer under 5 ILCS 140/3.5 and publish the contact on its website. For the major agencies:
- Illinois State Police: [email protected] (801 S 7th St, Suite 1000-S, Springfield 62703)
- Chicago Police Department: [email protected] / (312) 745-5308
- Cook County Sheriff: [email protected]
Submit a written request
Email is fastest. Cite 5 ILCS 140, identify yourself as a party to the crash, give the date, location, and case number, and request a fee waiver. The first 50 pages are free under the statute regardless. Use the sample letter in the next section.
Wait for the 5-business-day response
Under 5 ILCS 140/3(d), the agency must respond within 5 business days of receipt. They can extend once by 5 more business days with written notice and a stated reason. If you do not get a response, that is grounds to escalate.
Escalate to the Public Access Counselor if needed
The Illinois Attorney General’s Public Access Counselor (PAC) handles FOIA disputes under 5 ILCS 140/9.5. If an agency misses the deadline or denies your request improperly, you can file a Request for Review with the PAC. The PAC issues binding determinations and most agencies comply quickly when a request is opened.

Why citing the statute matters
When to Pay vs FOIA in Illinois
FOIA is free, but it is not always faster. Here is the calculus that works for most Illinois crashes:
- Use the paid portal if your insurance carrier has a 7-day documentation deadline, the SOL is approaching, or the responding agency has a reputation for slow FOIA replies. ISP $5 and Chicago PD $6 are typically faster than FOIA. Joliet/Rockford BuyCrash at $10-$15 is similar.
- Use FOIA if you have time, the agency is responsive, or your case involves issues beyond the report itself (witness statements, dash-cam, traffic-camera video, internal investigation memos). FOIA is the only way to get records beyond the SR-1050.
- Ask your insurance company first. Carriers have direct accounts with ISP, Chicago PD, BuyCrash, and most major Illinois agencies. They obtain the report at no cost to you as part of the claim investigation.
The 2-year SOL is unforgiving
How the Illinois Police Report Drives Your Settlement
Illinois follows a modified comparative fault rule with a 51% bar. The contributing-factor codes on the SR-1050 are the insurer’s first-pass fault percentage, and that percentage directly drives the settlement offer.
- 0% at fault (other driver coded): full value offers. Cook County juries trend plaintiff-friendly.
- 1-50% at fault: recovery is reduced by your percentage. 30% at fault on a $50,000 claim drops to a $35,000 starting point.
- 51% or more at fault: recovery is barred. This is why the SR-1050 codes matter so much. If you are coded for the only contributing factor in a two-car crash, the carrier will deny the claim outright.

Illinois Frequently Asked Questions
Is the Illinois State Police crash report on BuyCrash?
No. The Illinois State Police runs its own portal at isp.illinois.gov/CrashReports/EPay where the SR-1050 is $5 plus a 2.35% credit-card service fee. ISP does not currently use the BuyCrash/LexisNexis platform. Many Illinois municipal departments (Joliet, Rockford, and others) do route through BuyCrash.
How can I get an Illinois crash report free?
File a FOIA request under 5 ILCS 140 with the agency that responded to your crash. Most Illinois agencies waive fees for parties to the crash, and the first 50 black-and-white pages are free under the statute regardless. Public-interest fee waivers are available under 5 ILCS 140/6(c).
How long does an Illinois FOIA request take?
Illinois public bodies must respond within 5 business days under 5 ILCS 140/3(d). The deadline can be extended once for an additional 5 business days with written notice. Most crash report requests are fulfilled within the initial response window.
How much does Chicago Police Department charge for a crash report?
Chicago Police Department charges $6 for an online crash report at crash.chicagopolice.org for crashes from 2016 forward. A FOIA request to [email protected] may produce the report at no cost for parties to the crash, but the FOIA route is slower than the $6 online portal.
What is the Illinois statute of limitations for a personal injury claim?
Two years from the date of the crash under 735 ILCS 5/13-202. This makes obtaining the police report quickly important so you can evaluate liability before the deadline. If you are close to the SOL, paying for an immediate copy is usually worth it over a 5-business-day FOIA wait.
Does Illinois use comparative fault?
Yes. Illinois uses a modified comparative fault rule with a 51% bar. If you are 50% or less at fault, your damages are reduced by your percentage. If you are 51% or more at fault, you cannot recover any damages from the other driver. The contributing-factor codes on the SR-1050 are the insurer’s first-pass fault percentage.
Where is the Illinois State Police FOIA officer located?
The ISP Freedom of Information Officer is located at 801 South 7th Street, Suite 1000-S, Springfield, IL 62703. Email FOIA requests to [email protected]. For crash report requests specifically, [email protected] goes to Patrol Records at the same address, Suite 600-M, phone 217-785-0614.
Can I escalate if Illinois State Police does not respond?
Yes. The Illinois Attorney General’s Public Access Counselor (PAC) handles FOIA disputes. You can file a Request for Review under 5 ILCS 140/9.5 if a public body misses the 5-business-day deadline or denies your request improperly. The PAC issues binding determinations.
