Illinois Comparative Fault Law

Illinois draws a hard line at 50 percent. A driver who is 50 percent responsible for a crash on Route 13 can still collect damages, reduced by that share. A driver who is 51 percent responsible collects nothing. Whitfield Crosby & Flynn is a personal injury and wrongful death trial firm that represents injured people across Southern Illinois, including Williamson County, Franklin County and the communities along the Route 13 corridor, and that line is where many of our cases are won or lost.

Understanding Illinois comparative fault law matters from the first day of a claim, not the last. Insurance adjusters know the 50 percent rule better than most claimants do. They look for any fact that moves your share of blame upward: a few miles per hour over the limit, a phone in the cup holder, a decision to walk home on a dark road. Every percentage point they add comes straight off your recovery, and one point past the line ends it.

How the 50 Percent Rule Works Under 735 ILCS 5/2-1116

Illinois follows a modified comparative negligence system. The statute asks a jury, or a judge in a bench trial, to assign a percentage of fault to each person whose conduct contributed to the harm, including the injured plaintiff. If the plaintiff’s share is more than 50 percent, the claim is barred. If it is 50 percent or less, the plaintiff recovers, but the award is cut by the plaintiff’s own percentage.

The practical result is that fault allocation is a contest of evidence. The same crash can produce a full recovery, a reduced one, or nothing, depending on whose version of events the proof supports. That is why we treat liability as something to be built, not assumed, even in cases that look clear on the police report.

The rule applies to the whole range of injury claims: car and truck collisions, falls on unsafe property, workplace third-party suits, and medical negligence cases where a defendant argues the patient failed to follow instructions or disclose symptoms.

Whitfield Crosby & Flynn has more than 90 years of combined attorney experience and has played a role in settlements and verdicts totaling over $1 billion. We are trial lawyers first. We prepare every case for trial from day one, which matters in fault disputes because adjusters price a claim based on how well they think it will hold up in front of a jury. Clients have a direct line to their attorney, and we serve injury victims across Southern Illinois, Western Kentucky, Southeast Tennessee and Central Indiana.

Andrew Flynn has handled cases at every level of the Illinois state court system, including arguments before the Illinois Supreme Court, which is the court that ultimately shapes how fault statutes are applied. Sarah Bearden, a former public defender, brings courtroom experience to cross-examining the witnesses an insurer relies on to shift blame. Tim Crosby focuses his practice on personal injury and wrongful death trial work. Chuck Flynn is a member of the Multi-Million Dollar Advocates Forum and was recognized as an Attorney for Justice by the Tennessee Supreme Court.

Our results include a $5.78 million jury verdict for a law enforcement officer in a negligence case against a municipality, $3 million for a motorcycle rider against a trucking company, and $3.2 million for a motorcycle rider against a coal company. Motorcycle cases are a fair test of fault skills, because defendants routinely argue the rider was speeding or hard to see. Our attorneys are members of the American Association for Justice, the Kentucky Justice Association and the Tennessee Trial Lawyers Association, and the firm has been recognized by Best Lawyers: Ones to Watch. Prior results do not guarantee a similar outcome in any future case.

Where Fault Arguments Come Up in Illinois Injury Claims

Rear-End and Intersection Collisions: Defendants argue sudden braking, a late turn signal, or a stale yellow light. On Route 13 through Marion, Carterville and Carbondale, heavy turning traffic makes these arguments common.
Tractor-Trailer Wrecks: Carriers point to the passenger driver’s lane changes or following distance. Electronic logging device data, maintenance files and dashcam footage often answer those claims.
Motorcycle Crashes: Insurers say the rider was speeding or lane-splitting. Reconstruction work and independent witnesses are the usual counter.
Pedestrian and Cyclist Injuries: Dark two-lane county roads invite claims that the victim was not visible or crossed outside a crosswalk.
Premises Liability: A property owner may argue you should have seen the hazard or ignored a warning. Whether a danger was open and obvious becomes a fault question.
Medical Malpractice: Hospitals and physicians sometimes allege the patient delayed care or did not follow discharge instructions. Those allegations can reduce a verdict even when the standard of care was breached.
Mining and Industrial Accidents: Third-party claims against equipment makers and contractors often meet arguments that the worker caused or ignored the hazard.
Multi-Party Crashes: When several drivers or companies share blame, each gets a percentage, and the way blame is divided among them affects what you can recover.

What to Do Now If the Other Side Is Blaming You

Start by saying less. Do not give a recorded statement to the other driver’s insurer, and do not guess about speed, distance or what you could have done differently. Casual remarks like “I didn’t see him” or “I might have been going a little fast” get quoted back as admissions of fault.

Preserve evidence quickly. Photograph the scene, vehicle damage, skid marks, signage and lighting. Get names and numbers from witnesses before they scatter. Request the crash report from the responding agency, and keep every medical record and bill. Get medical care right away and follow the treatment plan, because a gap in care becomes another argument about your own conduct.

Know the deadlines. Illinois gives most injury claimants 2 years from the date of injury, and wrongful death claims run 2 years from the date of death. Medical malpractice claims run 2 years from discovery with an absolute 4-year repose period, subject to some exceptions. Product liability claims run 2 years, with a 12-year repose period from first sale. A claim against a city, county or other local government must be filed within one year. Missing any of these ends the case no matter how strong the fault evidence is.

Illinois injury suits in this region are filed in the circuit courts. Williamson County cases are heard in the Williamson County Courthouse in Marion, part of the 1st Judicial Circuit, which also covers Jackson, Saline, Alexander, Johnson, Massac, Pope, Pulaski and Union Counties. Franklin County cases are heard in Benton, in the 2nd Judicial Circuit. Some cases belong in federal court, and the Southern District of Illinois holds court in Benton, covering Franklin, Jackson, Saline and Williamson Counties among others.

Finally, talk to a lawyer before accepting any offer. An early settlement figure usually already assumes you carry a share of the blame, and once you sign a release, that assumption is permanent.

How an Attorney Fights a Fault Allocation

The work is concrete. We obtain the full crash file, event data recorder downloads, driver logs, cell records where relevant, scene video and maintenance history. We retain accident reconstructionists to test the other side’s story against physics, and medical experts to rebut claims that your own conduct worsened your injuries. We interview witnesses while memories are fresh and identify every responsible party and every insurance policy, because naming all at-fault parties keeps your own percentage in perspective.

We also prepare for the verdict form. Juries in Illinois are asked to put numbers on blame, and how a case is framed shapes those numbers. A defendant who looks reckless gets a larger share. A plaintiff who is credible and well documented gets a smaller one. Insurers track which firms take cases to a jury, and our preparation tends to change how they value the fault question before a courtroom is ever needed.

Illinois Comparative Fault: Common Questions

Can I still recover if I was partly at fault in Illinois?

Yes, as long as your share is 50 percent or less. Your damages are reduced by your percentage of fault. At 51 percent or more, you are barred from recovering anything.

What happens if I am exactly 50 percent at fault?

You can still recover. Illinois bars a claim only when the plaintiff’s fault is more than 50 percent, so at exactly 50 percent the award is simply cut in half.

Who decides the percentages?

The jury, or the judge if there is no jury. Before trial, the percentages are negotiated between lawyers and adjusters based on how each side expects the evidence to play out.

Does Illinois use the same rule as Kentucky, Tennessee or Indiana?

Not exactly. Kentucky is a pure comparative fault state with no cutoff. Tennessee and Illinois allow recovery only below or at the 50 percent mark in their own ways: Tennessee permits recovery when the plaintiff is less than 50 percent at fault, while Illinois permits it at 50 percent or less. Indiana bars a claimant whose fault is greater than the combined fault of the others, so 50 percent can still recover and 51 percent cannot.

Does the 2-year deadline change if I am partly at fault?

No. Fault percentages do not extend or shorten the filing deadline. The general injury deadline is 2 years from the date of injury, and shorter periods apply to claims against local governments.

Will my fault share reduce my medical bills coverage?

Fault reduces the damages award against the defendant. It does not by itself change what your own health insurance or medical payments coverage pays, though those insurers may seek reimbursement from any recovery.

What if I was hit by a drunk driver but I was not wearing a seatbelt?

The defendant may argue your choice made your injuries worse and ask a jury to assign you some fault. How that argument plays out depends on the medical evidence, which is why expert testimony on injury causation matters.

Can a pedestrian recover if they crossed outside a crosswalk?

Often, yes. Crossing outside a crosswalk is an argument for assigning the pedestrian some fault, not an automatic bar. A driver who was speeding, distracted or impaired can still carry most of the blame.

Should I accept a quick settlement that says I was partly responsible?

Be careful. A fast offer often builds in an assumption about your fault that a closer look at the evidence may not support. Once you sign a release, the number is final.

How long does a disputed-fault case take in Southern Illinois courts?

It varies with the number of parties, the need for experts and the court’s calendar. Cases with real fault disputes generally take longer than clear-liability cases, because both sides develop reconstruction and medical evidence before negotiating seriously.

Does comparative fault apply in wrongful death claims?

Yes. If the person who died bears some of the fault, the family’s recovery is reduced by that share, and a share above 50 percent bars the claim.

Is it worth hiring a lawyer if the other driver’s insurer says I was only a little at fault?

Often it is. “A little” can mean anything to an adjuster, and small shifts compound. A lawyer can test the figure against the evidence and push back on it before it becomes the basis of an offer.
