Illinois Statute of Limitations for Personal Injury: How Long You Really Have
Illinois generally gives injury victims two years to file — but several exceptions can shorten or extend that window dramatically. Here is what every Illinoisan should know before time runs out.
The Two-Year General Rule
Under 735 ILCS 5/13-202, most Illinois personal injury lawsuits must be filed within two years of the date the injury occurred. This applies to the majority of car crashes, slip-and-falls, and similar negligence claims. Miss the deadline and the court will almost certainly dismiss your case no matter how strong it is — the defendant only has to point to the calendar.
Two years can feel like a long time when you are focused on recovery, but it disappears faster than most people expect. Medical treatment, insurance back-and-forth, and the simple exhaustion of being hurt all eat into it. Evidence also fades: witnesses move, vehicles get repaired, and surveillance footage is overwritten. The earlier a claim begins, the stronger it tends to be.
Claims Against the Government Are Different
If your injury involves a city, county, the State of Illinois, a transit agency like the CTA or Metra, or another public body, the rules change sharply. The Local Governmental and Governmental Employees Tort Immunity Act (745 ILCS 10/8-101) generally imposes a one-year limitation period — half the usual time — and some claims require formal notice even sooner.
Because a surprising number of injuries involve a government defendant — a pothole, a transit bus, a municipal vehicle, a poorly maintained public sidewalk — it is dangerous to assume you have the full two years. When any public entity might be responsible, the safest move is to talk to an attorney immediately.
The Discovery Rule and Other Exceptions
Some injuries are not obvious right away. Illinois recognizes a 'discovery rule' that can delay the start of the clock until you knew, or reasonably should have known, that you were injured and that the injury may have been wrongfully caused. This matters most in medical cases, toxic exposure, and certain product cases.
Other adjustments exist too: claims by minors are generally tolled until they turn 18, and legal disability can pause the clock. Medical malpractice carries its own framework — a two-year discovery period with a four-year outer limit of repose (735 ILCS 5/13-212). These exceptions are fact-specific and easy to misjudge, which is exactly why they should be evaluated by a lawyer rather than guessed at.
