Illinois auto insurance — what affects your rate
Illinois auto rates reflect the state’s loss-cost mix — urban density, weather exposure, litigation costs, and how quickly the regulator lets carriers re-rate.
The four factors that drive your specific rate the most: ZIP code (theft + claim density), age (under 25 and over 70 pay materially more), vehicle (repair-cost class and theft rate), and driving record (one at-fault accident or moving violation typically lifts a rate 20-40%).
Minimum auto insurance required in Illinois
$25,000 BI per person / $50,000 per accident / $20,000 PD (25/50/20), plus uninsured-motorist coverage at the same limits.
