3 Facts About Multi-Vehicle Pileup Illinois

Last Updated: October 30, 2026

735 ILCS 5/2-1116 measures each person’s contributory fault as a share of the proximate cause. 735 ILCS 5/2-1117 separates medical expenses from the 25 percent line for the other damages.

Several Drivers

Section 2-1116 diminishes damages in proportion when the plaintiff’s contributory fault is not more than 50 percent of the proximate cause. Fault above that share bars recovery. The sequence of impacts is part of the proof of that share. 735 ILCS 5/2-1117 makes defendants found liable jointly and severally liable for past and future medical and medically related expenses, except as provided in section 2-1118. A defendant whose fault is less than 25 percent of the total fault of the plaintiff, the defendants sued, and any third-party defendant except the plaintiff’s employer is severally liable for the other damages. A defendant at 25 percent or more of that total is jointly and severally liable for the other damages. The source is P.A. 93-10 and P.A. 93-12, effective June 4, 2003. Each driver’s percentage does not by itself set the amount that driver pays.

Reconstructing the Impacts

Evidence of the impact sequence can include photographs of damage and final vehicle positions, witness accounts, and available dashcam or traffic-camera recordings. A vehicle may also have an event data recorder. NHTSA describes an EDR as recording technical vehicle and occupant information for seconds around a crash; it is not an audio or video recorder. The data available depends on the vehicle and device. Preserve available recordings and vehicle evidence while the sequence can still be investigated.

The Policies

625 ILCS 5/7-601(a) requires a liability policy in amounts no less than 625 ILCS 5/7-203, issued in accordance with sections 143a and 143a-2. Section 7-203 sets liability minimums of $25,000 for one person, $50,000 for two or more persons, and $20,000 for property damage. Nothing in section 7-601 deprives an insurer of a policy defense. 215 ILCS 5/143a(1) covers a person insured under the policy for bodily injury caused by an uninsured or hit-and-run motor vehicle, at the section 7-203 limits. The declarations and the policy state who that person is. Which policy responds depends on the policy terms and the facts.

With several vehicles, identify each potentially responsible driver’s liability policy and any UM/UIM policy that insures the injured person. Under 215 ILCS 5/143a-2(4), the underinsured-vehicle comparison uses the sum of the applicable bodily injury liability limits and the insured’s UIM limit. The UIM insurer’s limit is reduced by amounts actually recovered under the applicable bodily injury coverage on that vehicle. Subsection (5) permits policy terms that cap benefits at the higher applicable limit where more than one coverage is available; covering several vehicles under one policy does not increase that limit. The policy definition of an insured and the actual policy terms still govern the particular claim.

The Filing Period

735 ILCS 5/13-202 is two years next after accrual for the private injury action that section describes. 745 ILCS 10/8-101(a) is one year from the date the injury was received or the cause of action accrued, against a local entity or its employees, other than the patient-care action in subsection (b). 745 ILCS 10/1-206 says a local public entity does not include the State or a department of the State. A tort claim against the State is filed in the Court of Claims. 705 ILCS 505/8(d) gives that court jurisdiction if a like cause of action would lie against a private person or corporation. The statutory base for a tort award is $2,000,000 to or for the benefit of any claimant. The same subsection requires the court to adjust that maximum each year for any increase in the Consumer Price Index For All Urban Consumers for the previous calendar year, as determined by the United States Department of Labor. The Comptroller’s 2026 award-limit notice states the adjusted tort limit for 2026 at $2,629,104.52. The amount for another year is the adjustment published for that year. Neither the statutory base nor the adjusted maximum applies to an award arising out of the operation by a State employee of a vehicle owned, leased, or controlled by the State. 705 ILCS 505/22(h) says all other claims must be filed within 2 years after the claim first accrues, with the stated saving for a minor or a person under legal disability. 705 ILCS 505/22-1 requires a notice, within one year from the injury or accrual, before a Court of Claims action for damages on account of an injury to the person. The same section says a claimant is not required to file that notice if the claim is filed within one year of accrual.

Frequently Asked Questions

How is fault determined in a multi-vehicle pileup in Illinois?

Section 2-1116 is the plaintiff’s share of the proximate cause. Damages are diminished in proportion when that share is not more than 50 percent. A share above 50 percent bars recovery. The order of the impacts is part of the proof.

Can I be blamed for a pileup if I was pushed into the car ahead of me?

Section 2-1116 uses the plaintiff’s own share of the proximate cause. Whether one vehicle pushed another is part of that proof. The section uses the share the evidence supports.

What if multiple drivers share fault in a pileup?

Section 2-1117 makes defendants found liable jointly and severally liable for past and future medical and medically related expenses, except as provided in section 2-1118. A defendant under 25 percent of the stated total is severally liable for the other damages. A defendant at 25 percent or more is jointly and severally liable for the other damages.

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

Section 13-202 is two years next after accrual for the private injury action it describes. Section 8-101(a) is one year against a local entity or its employees, other than subsection (b). A claim against the State uses sections 8(d), 22(h), and 22-1.
