Were You Partially at Fault for Your Accident? Here's What Illinois Law Says About Your Claim

You're dealing with injuries after a car accident, a slip and fall, or some other incident that wasn't entirely your fault. Maybe you were speeding a little. Maybe you weren't watching where you stepped. And now the insurance company is telling you that because you share some of the blame, you don't deserve full compensation — or any compensation at all.

That's not how it works in Illinois. And understanding the law could mean thousands — even tens of thousands — of dollars in your pocket.

At Stavros Law Offices, we've been fighting for injured people in Wheeling, Cook County, Lake County, and across suburban Chicago since 1978. We're second generation trial lawyers — three brothers, one mission: making sure you get what you're owed, even when the other side tries to shift the blame.

What Is Comparative Fault in Illinois?

Let's start with the basics. Comparative fault (sometimes called "comparative negligence") is the legal framework Illinois uses to determine how much compensation an injured person can receive when more than one party shares responsibility for an accident.

In plain English: if you were partially at fault for what happened, your compensation gets reduced by your percentage of fault — but you can still recover damages.

Illinois follows a modified comparative fault system under 735 ILCS 5/2-1116. Here's the key rule:

• You can recover damages as long as you are not more than 50% at fault for your injury.
• If you are 51% or more at fault, you recover nothing.
• Your damages are reduced by your percentage of fault.

This is sometimes called the 50% bar rule. If you're 50% at fault, you can still recover. At 51% or more, you're barred completely. That cutoff makes the fault percentage assigned to you one of the most important numbers in your case.

How Fault Percentages Actually Reduce Your Damages

Here's where it gets practical. Under Illinois's modified comparative fault system, the math is straightforward:

Example: You're in a car accident. Your total damages — medical bills, lost wages, pain and suffering — come to $100,000. But the jury determines you were 30% at fault (maybe you were going a bit over the speed limit). Your recovery is reduced by 30%:

• $100,000 x 30% fault = $30,000 reduction
• You recover $70,000

Now flip it. If you were found to be 55% at fault? Under Illinois law, you get nothing. That's the 50% bar in action.

This is exactly why the percentage assigned to you matters so much — and why insurance companies fight so hard to inflate it.

Real-World Examples of Comparative Fault in Illinois

Comparative fault comes up in almost every personal injury case. Here are some common scenarios we see at our Wheeling office:

Intersection car accident: You enter an intersection on a yellow light. Another driver runs their red. You're hit broadside. The insurance company argues you should have stopped. A jury might assign you 20% fault and the other driver 80% — reducing your damages by 20%, but you still recover the majority.

Rear-end collision with a twist: Someone rear-ends you, but your brake lights were malfunctioning. Normally, the rear driver is presumed at fault, but the broken lights give them an argument. You might be assigned 10-15% fault.

Slip and fall: You slip on an icy sidewalk outside a store in Cook County. The property owner failed to salt, but you were looking at your phone. The defense argues you weren't paying attention. Fault might be split 25% to you, 75% to the property owner.

Pedestrian accident: You're crossing the street outside a crosswalk when a distracted driver hits you. You share some fault for jaywalking, but the driver was texting. A jury might assign 30% to you and 70% to the driver.

In every one of these cases, the specific percentage makes a real difference in your compensation. That's why evidence gathering starts from day one.

How Insurance Adjusters Use Comparative Fault to Lowball You

Here's something most people don't realize: insurance adjusters are trained to use comparative fault as a tool to reduce what they pay you. It's not personal — it's their job.

Their playbook looks something like this:

• They take your recorded statement early — before you have a lawyer — hoping you'll say something that sounds like you're accepting blame.
• They inflate your fault percentage in their internal evaluation to justify a lower offer.
• They cherry-pick evidence — maybe you mentioned being "in a hurry" or "not feeling great" before the accident.
• They present their number as final, hoping you'll accept without pushing back.

We've seen adjusters try to pin 40-50% fault on clients who were clearly only 10-15% responsible. Why? Because the higher your fault percentage, the less they pay. If they can push you past that 50% threshold, they pay nothing.

This is one of the biggest reasons to have an experienced personal injury attorney on your side before you talk to any insurance company.

How Comparative Fault Plays Out at Trial in Illinois

If your case goes to trial, the process works like this:

• Both sides present evidence about what happened and who was at fault.
• The jury assigns a fault percentage to each party involved — you, the defendant, and any other responsible parties.
• The jury also determines your total damages — the full value of your injuries, losses, and suffering.
• The judge then reduces the verdict by your assigned fault percentage.

So if the jury says your damages are $200,000 and you're 25% at fault, the judge enters a judgment for $150,000. It's automatic — the jury doesn't do the math, the court does.

This is why trial preparation matters. We build cases that minimize our clients' fault exposure and maximize the evidence against the defendant. Every photograph, every witness statement, every expert opinion can shift those percentages.

Why Having an Attorney Makes the Difference

When the insurance company says you were 40% at fault, you need someone who can say, "No, here's why it was 15%." That's what we do.

At Stavros Law Offices, we:

• Investigate the accident thoroughly — police reports, witness interviews, surveillance footage, accident reconstruction when needed.
• Push back on inflated fault claims with evidence and expert analysis.
• Negotiate aggressively with insurance companies who try to lowball you.
• Take cases to trial when a fair settlement isn't on the table. Insurance companies know which firms actually go to court — and they negotiate differently when they know you're serious.

And here's what matters most: you don't pay unless we win. Our personal injury cases are handled on a contingency fee basis. There's no upfront cost, no hourly billing. We get paid when you get paid.

Remember: in Illinois, you have two years from the date of your injury to file a personal injury lawsuit. Don't wait until it's too late to protect your rights.

Frequently Asked Questions About Comparative Fault in Illinois

Can I still get compensation if I was partially at fault for my accident in Illinois?

Yes. Under Illinois's modified comparative fault law (735 ILCS 5/2-1116), you can recover damages as long as you are not more than 50% at fault. Your compensation is reduced by your percentage of responsibility.

What is the 50% bar rule in Illinois?

The 50% bar rule means that if you are found to be 51% or more at fault for your accident, you cannot recover any damages. If you are 50% or less at fault, you can still recover, but your award is reduced by your fault percentage.

How do insurance companies use comparative fault against me?

Insurance adjusters often try to inflate your percentage of fault to reduce the amount they owe you. They may take early recorded statements, cherry-pick evidence, or argue that your actions contributed more to the accident than they actually did. Having an attorney helps protect you from these tactics.

Does Illinois follow a no-fault insurance system?

No. Illinois is an at-fault state, which means the person who caused the accident is responsible for paying damages. This is why determining each party's percentage of fault is so critical to your claim.

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

The statute of limitations for personal injury cases in Illinois is two years from the date of injury. If you miss this deadline, you generally lose the right to file a lawsuit. Contact an attorney as soon as possible to protect your claim.
