Illinois: At-Fault Insurance Explained

Illinois's At-Fault Insurance System Explained

Illinois uses an at-fault (tort) insurance system, meaning the driver who caused the accident is financially responsible for damages.

How At-Fault Insurance Works in Illinois

At-Fault Basics

In Illinois's at-fault system:

• The at-fault driver's insurance pays for your damages
• You have three options: (1) file with their insurer, (2) file with yours and let them subrogate, (3) sue directly
• You can recover: medical expenses, lost wages, pain and suffering, and property damage
• Illinois's comparative negligence rules may reduce your recovery by your percentage of fault

At-fault states like Illinois typically see:

• Higher average settlements (full tort damages available)
