Chicago

Chicago is a city of about 2.73 million people (U.S. Census Bureau, July 2025 estimate), and getting hurt here means running into a specific set of institutions: a particular courthouse on Washington Street, a small group of Level I trauma centers, a transit agency with its own shortened deadline, and a street grid with corridors the city itself has formally identified as dangerous.

That specificity matters, because the generic advice you find online is often wrong for Chicago. "You have two years to file" is true for an ordinary car crash between two private drivers. It is not true if a city vehicle was involved, if you were hurt on a CTA bus or train, or if you fell on property owned by the city, the Park District, or the Chicago Housing Authority — those are generally one-year deadlines under the Local Governmental and Governmental Employees Tort Immunity Act (745 ILCS 10/8-101) and the Metropolitan Transit Authority Act (70 ILCS 3605/41). People lose real claims to that gap every year.

One correction worth making, because outdated pages all over the internet still get it wrong: the CTA used to require a written notice within six months of an injury, separate from the filing deadline. That notice requirement was repealed effective June 1, 2009 (P.A. 96-12). What remains is the one-year limitation period. If a website told you your CTA claim is dead because you missed a six-month notice, that website is roughly seventeen years out of date. Ask an attorney rather than giving up.

On the traffic side, Chicago is not an abstraction either. The city recorded 100 traffic deaths in 2025, its lowest total since 2016 and down about 46% from a peak of 186 in 2021 (Chicago Department of Transportation data, reported February 2026). Improvement, genuinely — and still a hundred families. Statewide, Illinois logged 303,913 crashes with 89,023 people injured in 2024 (IDOT, Crash Trends 2020–2024).

We are an intake and referral service, not a law firm, and we do not have a Chicago office or Chicago lawyers on staff — we would rather tell you that than imply otherwise. What we do is take your story once, in English or Spanish, at any hour, explain how this works in the city you are actually in, answer what we can and tell you plainly which questions only an attorney should answer, and then, with your permission, connect you with a licensed Illinois attorney in our network who handles cases like yours in Cook County.

The Chicago deadlines that catch people out

If your claim is against another private driver or a private business, the general Illinois deadline is two years from the date of injury (735 ILCS 5/13-202).

In a city like Chicago, though, a large share of injuries involve a public defendant, and those are generally one year:

• The City of Chicago — a city truck, a police vehicle, a pothole, a city-owned sidewalk or building (745 ILCS 10/8-101)
• The Chicago Transit Authority — a bus, a train, a platform, a station (70 ILCS 3605/41)
• The Chicago Park District, Chicago Public Schools, the Chicago Housing Authority, and other local public entities (745 ILCS 10/8-101)

Two more Chicago-specific realities. First, a claim against a bar or liquor licensee under the Dram Shop Act must be brought within one year (235 ILCS 5/6-21) — relevant in a city with this many licensed premises. Second, if the injured person is a child, the clock generally does not start until their 18th birthday (735 ILCS 5/13-211).

None of this is legal advice, and the deadline that applies to you depends on facts we do not have. But if there is any chance a public entity is involved, treat the deadline as one year and call somebody now.

Where a Chicago case actually gets filed

Chicago injury cases are filed in the Circuit Court of Cook County, and which part of it depends on how much the claim is worth.

For cases arising in the City of Chicago — the First Municipal District — the dividing line is $30,000. Claims up to $30,000 are handled in the Municipal Department; claims exceeding $30,000 go to the Law Division. That threshold is different in the suburbs, where it is $100,000, which is one of the more counter-intuitive facts about litigating in this county.

Both the Law Division and the First Municipal District sit in the Richard J. Daley Center at 50 W. Washington Street, a building most Chicagoans know by its Picasso rather than its docket. The Law Division handles motor vehicle injury, medical malpractice, product liability, construction injury, premises liability and wrongful death cases.

Civil filing in Illinois is electronic and mandatory under Illinois Supreme Court Rule 9(a), through the statewide eFileIL system, and has been since January 1, 2018. Your attorney handles that; you will not be standing in a line.

One local mechanism worth knowing about: Cook County runs mandatory arbitration for smaller claims. Under Cook County Circuit Court Rule 18.3(b), Municipal District personal injury actions seeking not more than $30,000 are assigned to a three-member arbitration panel. Awards are non-binding — a party can reject an award and proceed to trial.

If your case is a workers' compensation claim, none of the above applies. Those go to the Illinois Workers' Compensation Commission, whose Chicago hearing rooms are also in the Daley Center, in Room LL-17, with administrative offices at 69 W. Washington St., Suite 900.

The streets the city itself flagged

Chicago does not leave "dangerous street" to opinion. Under Vision Zero Chicago, launched in 2017, the city analysed IDOT crash data for non-expressway streets and formally designated 43 High Crash Corridors covering roughly 70 miles, plus 8 High Crash Areas — the community areas with the worst composite severity scores. Fifteen of the 43 corridors are downtown.

Corridors on that official list include Western Avenue in three separate stretches, Ashland Avenue in three, Pulaski Road in two, Stony Island Avenue in two, plus Cicero Avenue, 79th Street, Halsted, Cottage Grove, Milwaukee, Damen, Fullerton, Devon, Belmont, Roosevelt, Garfield Boulevard, and DuSable Lake Shore Drive between Division and Roosevelt.

CDOT has since moved to a High Injury Network framework and published a Chicago Traffic Crashes Annual Report in 2025 covering 2024 data. Crash data is available daily on the City of Chicago open data portal. Because the framework has changed since 2017, read the corridor list above as the city's 2017 analysis rather than a current ranking, and check the city's latest publication for where it stands today.

We are deliberately not publishing a ranked list of "most dangerous intersections." Those lists circulate widely, but the ones we could find were produced by law firms using proprietary scoring rather than by any government agency, and two versions of the most-cited study report materially different crash counts for the same intersections. We would rather cite the city's own designation than repeat a number we cannot stand behind.

On the expressways: the Jane Byrne Interchange, where the Kennedy, the Dan Ryan and the Eisenhower meet, carried roughly 400,000 vehicles a day and averaged about 940 crashes per year before its $804.6 million reconstruction was completed in December 2022. IDOT projected a 25% reduction in crashes from that work. Anyone still describing it with pre-2022 numbers is quoting a road that no longer exists in that configuration.

If the other side says it was your fault

Illinois is a modified comparative negligence state. Under 735 ILCS 5/2-1116, you are barred from recovering only if your share of the fault is found to be more than 50%. At 50% or less, you can recover, and your damages are reduced in proportion to your share.

Note the exact wording, because the common shorthand is slightly wrong: the statute says "more than 50%," not "51% or more." Someone found 50.5% at fault is barred. That precision is why the percentage argument is worth having properly, with someone who does it for a living.

The courthouse where your case would live

Chicago injury cases are filed in the Circuit Court of Cook County. Which department depends on the value of the claim, and in the City of Chicago the dividing line is $30,000.

• Richard J. Daley Center — Law Division and First Municipal District — 50 W. Washington St., Chicago, IL 60602. Law Division for claims exceeding $30,000 arising in Chicago: motor vehicle injury, premises liability, medical malpractice, product liability, construction injury and wrongful death. First Municipal District for claims up to $30,000. Law Division Clerk's office is in Room 801.
• Illinois Workers' Compensation Commission — Chicago hearing site — Richard J. Daley Center, 50 W. Washington St., Room LL-17, Chicago, IL 60602. Work injury claims are heard here rather than in the Circuit Court. Administrative offices are at the Cook County Office Building, 69 W. Washington St., Suite 900.
• Cook County Mandatory Arbitration Center — 222 N. LaSalle St., Chicago, IL. Municipal District personal injury claims of not more than $30,000 go to a three-member arbitration panel under Circuit Court Rule 18.3(b). Awards are non-binding and can be rejected in favour of trial.
