Sharing some blame for an accident does not automatically end a claim in Illinois. State law reduces compensation based on fault rather than wiping it out entirely, though there is one specific point where recovery does disappear completely.
Illinois Uses A Modified Comparative Fault Standard
Under Illinois law, an injured person can recover damages as long as their own share of fault stays below 51 percent. This standard is set out directly in the state’s civil procedure statute governing negligence claims, and it applies broadly across car accidents, premises cases, and most other injury claims. Once fault reaches that 51 percent mark, recovery is barred entirely, no matter how serious the injury.
How Compensation Gets Reduced Below That Line
For anyone under the 51 percent threshold, the math is fairly direct. Total damages get reduced by whatever percentage of fault is assigned to the injured person. Someone found 20 percent at fault in a $150,000 case would recover $120,000, while someone found 45 percent at fault in that same case would recover about $82,500. The closer that percentage climbs toward 51, the more it costs in real dollars.
Why The Line At 51 Percent Feels So High Stakes
A single percentage point separates full eligibility from a total bar on recovery, which is exactly why insurers spend so much energy trying to push fault estimates upward. A finding of 49 percent still allows recovery, reduced accordingly, while 51 percent ends the claim outright. That narrow gap is often where negotiations get the most contentious.
What Actually Shapes A Fault Percentage
Fault findings are rarely based on a single fact. They usually come together from multiple sources, including:
- The police report and any citations issued at the scene
- Photos or video showing vehicle positions and road conditions
- Statements from witnesses who saw what happened
- Data from vehicle event recorders when it is available
How This Plays Out In Chicago Specifically
Chicago’s dense intersections, heavy pedestrian traffic, and mix of rideshare and delivery vehicles mean many crashes here involve more than one party whose actions contributed to what happened. Sorting out an accurate percentage for each party often requires pulling together several types of evidence rather than relying on a single account of the crash, which is where a Chicago personal injury lawyer can help build out the full picture.
Getting A Fair Read On Where Fault Lands
Because the fault percentage has such a direct effect on what a claim is worth, it helps to have someone review the evidence before accepting an insurer’s initial assessment. A Chicago personal injury lawyer can look at the police report, any available footage, and witness accounts to see whether the fault split an insurer is offering actually holds up.
