Is Illinois a No Fault State
No, Illinois is not a no-fault state for car accidents; Illinois operates under a traditional fault-based (tort liability) system paired with a modified comparative negligence rule, meaning the driver who caused the crash is financially responsible for all property damage and medical injuries.
Illinois Fault-Based Insurance and Modified Comparative Negligence
Under Illinois Compiled Statutes (735 ILCS 5/2-1116), you can recover damages from the at-fault driver as long as you are less than 51% responsible for the accident.
| Legal Element | Illinois Statutory Rule | Practical Impact on Injury Claims |
|---|---|---|
| Liability Insurance System | At-Fault / Tort System | Victims file claims directly against at-fault driver policy |
| Comparative Fault Standard | Modified Comparative Fault (51% Bar) | You can recover if 50% or less at fault; damages reduced by % |
| Minimum Liability Coverage | 25/50/20 Mandatory Insurance | $25k bodily injury / $50k per accident / $20k property |
| Statute of Limitations | 2 Years (Personal Injury) / 5 Years (Property) | Lawsuit must be filed within 24 months of accident |
