Minimum Coverage Requirements in Illinois
Illinois operates as an at-fault state and requires minimum liability coverage of 25/50/20: $25,000 bodily injury per person, $50,000 per accident, and $20,000 property damage. While Illinois does not legally mandate mature driver course discounts, most major carriers operating in the state offer them voluntarily, typically ranging from 5–10% for drivers who complete an approved defensive driving course. The Illinois Department on Aging partners with AARP and other organizations to offer these courses both online and in-person at no cost or reduced rates for seniors. Senior drivers should verify discount availability with their specific carrier, as requirements and percentages vary by insurer.
How Much Does Car Insurance Cost in Illinois?
Auto insurance rates for senior drivers in Illinois typically decrease until age 70, then begin rising as insurers apply age-based risk factors. Drivers aged 65–69 often pay less than middle-aged drivers due to decades of experience and clean records, while those 75 and older face steeper increases. Illinois insurers consider location heavily — Cook County seniors pay 30–50% more than downstate drivers due to higher accident frequency, theft rates, and uninsured motorist density in the Chicago metro area.
What Affects Your Rate
- Mature driver course discounts of 5–10% are available from most Illinois insurers for drivers who complete an approved defensive driving course, typically valid for three years and renewable
- Low-mileage programs can reduce premiums by 10–20% for senior drivers who no longer commute — Illinois insurers increasingly offer pay-per-mile and usage-based options ideal for retirees driving under 7,500 miles annually
- Location within Illinois affects senior rates significantly — Cook County seniors average 35–45% higher premiums than those in McLean or Champaign counties due to congestion, theft, and uninsured motorist rates in metro Chicago
- Bundling home and auto insurance produces discounts of 15–25%, particularly valuable for senior homeowners with paid-off properties who can consolidate coverage
- Credit-based insurance scoring remains legal in Illinois and affects senior rates — maintaining strong credit can reduce premiums by 20–30% compared to drivers with poor credit, even with identical driving records
- Loyalty discounts of 5–15% apply after 3–5 years with the same carrier, though senior drivers should still compare rates every two to three years as competitor pricing shifts
Coverage Types
Liability Insurance
Covers injury and property damage you cause to others. Illinois minimums of 25/50/20 are often inadequate for senior drivers with assets to protect.
Uninsured Motorist Coverage
Protects you when hit by a driver with no insurance or insufficient coverage. Illinois requires insurers to offer this, but you can decline in writing.
Comprehensive Coverage
Covers non-collision damage: theft, vandalism, hail, fire, and animal strikes. Optional unless required by a lender.
Collision Coverage
Pays for damage to your vehicle in an accident, regardless of fault. Required by lenders, optional for paid-off vehicles.

Covers medical expenses for you and passengers regardless of fault, in amounts typically ranging from $1,000 to $10,000.
Full Coverage Package
Combines liability, comprehensive, collision, uninsured motorist, and medical payments into a complete protection package.
