Illinois is a fault-based (tort) auto insurance state, meaning the at-fault driver’s insurance covers damages instead of each driver’s own policy. This system allows victims to sue for non-economic damages like pain and suffering if injuries meet specific thresholds. Illinois courts enforce comparative negligence rules, reducing compensation proportionally to the victim’s percentage of fault.

No, Illinois does not require personal injury protection (PIP) coverage, as it is a fault-based state that relies on liability insurance for medical expense reimbursement. However, drivers can voluntarily purchase PIP or MedPay to cover medical costs regardless of fault, though it’s less common than in no-fault states like Michigan. Most Illinois policies include MedPay as an optional add-on.

An SR-22 is required in Illinois if your driver’s license is suspended due to serious violations like DUI, reckless driving, or driving without insurance, and you must prove future financial responsibility.

Filing an SR-22 often increases annual premiums by $500 or more in Illinois.
