What to compare when shopping car insurance in Illinois
Auto insurance premiums for the same driver vary 30–60% across carriers. These are the factors that matter most.
Coverage level vs. minimum
Illinois sets minimum liability requirements — but minimums are rarely adequate. Consider liability limits above the minimum, plus uninsured/underinsured motorist coverage if not already required.
Carrier complaint ratio
The NAIC publishes complaint ratios for every licensed carrier at naic.org. A carrier with a low complaint ratio relative to its market share is a signal of better claims-handling quality.
Comprehensive and collision
Comprehensive covers non-collision events (theft, hail, flood, wildlife). Collision covers at-fault accidents. If your vehicle has significant value, both are worth comparing across deductible options.
Discounts
Safe driver, multi-policy (bundling home and auto), low-mileage, good student, and telematics/usage-based discounts can reduce premium 10–25%. Each carrier weights these differently.
Claims process reputation
J.D. Power auto insurance claims satisfaction studies and NAIC complaint ratios are the two most reliable public data sources for comparing how carriers actually handle claims.
Carrier license in Illinois
Verify any carrier is licensed with Illinois Department of Insurance before purchasing a policy. Unlicensed carriers have no regulatory recourse and are a fraud risk.
