Illinois FAQ

Frequently Asked Questions

Illinois gives you two years from the accident date to file a personal injury lawsuit. That clock runs regardless of whether you're still receiving medical treatment or negotiating with an insurance adjuster, so an open claim doesn't pause it. Because Illinois' fault rule can eliminate your recovery entirely past a certain point, documenting the crash early, police report, medical records, witness contact info, gives you a stronger position long before that two-year deadline becomes a pressure point.

Illinois follows modified comparative negligence with a 51% bar under 735 ILCS 5/2-1116 - you can recover damages as long as you are not more than 50% responsible. Your compensation is reduced by your own percentage of fault, so 35% fault means a 65% recovery, and exactly 50% fault still allows recovery with damages reduced by half. At 51% or more, Illinois law bars recovery entirely. Because insurers know this threshold determines their exposure, they often push hard on fault percentage in negotiations.

Illinois requires drivers to carry at least $25,000 per person and $50,000 per accident for bodily injury, plus $20,000 for property damage, written as 25/50/20. This coverage compensates people the at-fault driver injures or whose property they damage, not the at-fault driver's own losses. Because these figures are legal minimums, a serious crash involving significant medical treatment or vehicle damage can exceed them, shifting attention to what other coverage is available.

Illinois insurers must offer uninsured motorist coverage on every auto policy, though a driver can reject it in writing. If no written rejection exists, the coverage applies. It matters because it pays out when the at-fault driver carries no insurance or insufficient limits to cover your injuries. With Illinois' liability minimums capped at $50,000 per accident, UM coverage is often what closes the gap after a serious multi-party crash.
