Does Illinois have no-fault insurance?⌄
No. Illinois is an at-fault state. When an accident occurs, the at-fault driver's liability coverage pays for the other driver's injuries and property damage. This means your state-minimum liability coverage must be high enough to cover a potential claim against you.
Why is car insurance so cheap in Illinois?⌄
Rural Illinois is very affordable; Chicago metro skews the average upward with urban claims frequency.
Is my credit score used for car insurance in Illinois?⌄
Yes, in most cases. Illinois allows insurers to use a credit-based insurance score (distinct from your FICO) to predict claim likelihood. A poor credit-based score can add 20-100% to your premium. Improving your credit over 12-24 months can generate meaningful savings at renewal.
