The rules — with the statutes

What Illinois law does to your number

Shared fault: Modified comparative — 51% bar

You recover if your fault is 50% or less, reduced by your share; more than 50% bars the claim.735 ILCS 5/2-1116

Filing deadline

2 years for personal injury735 ILCS 5/13-202. The clock is jurisdictional — one day late and no court will hear the case.

Damage caps

  • Compensatory damages: No caps — Illinois courts have struck down every attempt: general tort caps in Best v. Taylor Machine Works (1997) and medical-malpractice caps in Lebron v. Gottlieb (2010), both as unconstitutional 'legislative remittitur.'

Insurance rules

At-fault state — no PIP mandate.

Minimum liability coverage: 25/50/20 — $25,000 per person, $50,000 per accident, $20,000 property damage.625 ILCS 5/7-203 — policy limits are the practical ceiling on most settlements, which is why identifying every available policy (including your own underinsured-motorist coverage) matters.

The 25% rule quietly caps multi-defendant recoveries

Illinois's modified joint-and-several statute makes any defendant found less than 25% at fault only severally liable for non-economic damages — so in multi-defendant cases, a minor-share deep pocket can't be made to pay the whole pain-and-suffering award. Medical expenses stay joint and several. It's a collectability rule most valuation discussions skip.735 ILCS 5/2-1117

Common questions

FAQ

How are car accident settlements calculated in Illinois?

The same multiplier method used everywhere — (medical bills + lost wages) × a 1.5–5× severity multiplier + property damage — then Illinois's fault rule is applied: You recover if your fault is 50% or less, reduced by your share; more than 50% bars the claim. The calculator on this page runs exactly that math and prints every line.

How long do I have to file an injury claim in Illinois?

2 years for personal injury (735 ILCS 5/13-202). Miss the deadline and the claim is barred permanently, no matter how strong it is — and claims against government entities often have much shorter notice requirements.

Are damages capped in Illinois?

Compensatory damages: No caps — Illinois courts have struck down every attempt: general tort caps in Best v. Taylor Machine Works (1997) and medical-malpractice caps in Lebron v. Gottlieb (2010), both as unconstitutional 'legislative remittitur.'
