Minimum Coverage Requirements in Illinois
Illinois requires minimum liability coverage of 25/50/20: $25,000 bodily injury per person, $50,000 per accident, and $20,000 property damage. Drivers with DUI convictions, multiple at-fault accidents, driving without insurance, or license suspensions typically must file SR-22 proof of financial responsibility with the Illinois Secretary of State for three years. The state uses a point system where three moving violations in 12 months trigger automatic suspension, creating both point-related rate increases and potential SR-22 requirements. Uninsured motorist coverage is not mandatory but strongly recommended since approximately 12–15% of Illinois drivers operate without insurance.
How Much Does Car Insurance Cost in Illinois?
High-risk auto insurance costs in Illinois vary widely based on violation type, point accumulation, location, and carrier availability. A DUI conviction typically increases premiums by 150–300%, while a single at-fault accident may raise rates 30–60%; drivers needing SR-22 filing face additional premium surcharges because they are restricted to non-standard carriers. Urban areas like Chicago, Aurora, and Joliet see higher rates due to accident frequency and theft risk, while rural counties offer modestly lower premiums but fewer non-standard carrier options.
What Affects Your Rate
- Violation type and severity—DUI convictions increase premiums 150–300%, while single at-fault accidents raise rates 30–60%
- Point accumulation on your Illinois driving record—each point typically adds 10–20% to premiums, and three violations in 12 months trigger suspension
- SR-22 filing requirement—adds $15–$35 filing cost and restricts you to non-standard carriers with premiums 150–300% higher than standard market
- Location—Cook County, DuPage County, and Will County have the highest rates due to density and accident frequency; rural counties offer 10–20% lower premiums but fewer carrier options
- Coverage level and deductibles—raising collision and comprehensive deductibles from $500 to $1,000 can reduce premiums by 15–25%
- Time since violation—most carriers reduce surcharges after 3 years violation-free, and many high-risk drivers can return to standard market after 5 years clean
