Why Is Car Insurance So Expensive in Illinois? (2026): Statewide Averages Sit Near the National Level, but Chicago Theft, Traffic, and Lawsuits Push Bills Up

Illinois car insurance feels expensive because the bills climbed fast, not because the state is the priciest in the country. Statewide averages sit near or below national figures in most 2026 studies, but Chicago drivers pay far more than the rest of the state, and renewal notices that jumped 20% or more left many households stunned.

Auto theft, dense traffic, severe weather, injury lawsuits in Cook County, and the same repair and medical cost inflation hitting every state all feed the price. Rates fell during 2025 but rose again in the first half of 2026, and comparison shopping still pays off.

Illinois is not the most expensive state, but Chicago is expensive within it, and shopping around still cuts the bill.

The sources agree on the causes and differ on how high rates are. Insurify attributes Illinois pricing to severe weather, heavy congestion, and theft, and notes Chicago sits above the state average while Bloomington drivers pay some of the lowest rates because of low population density. CoverageAdvisor adds Cook County’s reputation for large injury lawsuits and a spike in Kia and Hyundai thefts in 2022 and 2023. ABC7 Chicago quotes Chicago Consumer’s Checkbook saying drivers saw renewals rise 20% or more because claims cost more to settle.

Is car insurance really expensive in Illinois?

Finhabits calls Illinois slightly above the national average, while PocketGuard, citing Insurify’s 2026 data, says Illinois sits below the national average even though premiums there climbed 41% over three years, nearly double the national pace. The dollar figures in the table below depend on the sample used.

Why is car insurance so expensive in Chicago?

Chicago combines several of the costliest ingredients for insurers in one place.

• Theft is a large factor. Illinois has the fifth highest auto theft rate in the country, per Experian citing NICB data, and Chicago thefts spiked after a social media trick made certain Kia and Hyundai models easy to steal, according to CoverageAdvisor.
• Traffic is heavy. Illinois drivers logged more than 106 billion miles in 2025, with over 30 billion in Cook County alone, and more than 300,000 vehicles use Interstate 90 each day, per Insurify.
• Injury lawsuits raise costs. CoverageAdvisor says Cook County has a reputation for large injury suits, and carriers cite rising attorney involvement on injury claims in their rate filings.
• Uninsured drivers shift costs. The Insurance Research Council puts Illinois uninsured drivers at 16.3%, which Experian cites as a driver of higher rates. Finhabits gives a lower estimate of about 12% for Chicago.
• Weather causes claims. Every Illinois county is at risk of severe storms that can cause tornadoes and hail damage, and many counties face flood risk, according to Insurify.

Finhabits estimates Chicago drivers pay 30% to 50% more than the statewide average. Insurify’s city averages agree: dense areas cost more, while Bloomington sits near the low end.

Why did my car insurance go up in Illinois?

Your rate can rise even if you have not filed a claim. Insurance.com cites several years of high inflation, repair costs on technologically advanced vehicles, longer repair times due to parts shortages, litigation, and natural disasters. Liberty Mutual told ABC7 that inflationary increases in labor rates, repairs, used car prices, and medical costs are behind higher premiums for most customers nationwide.

Experian adds that healthcare and injury severity matter too: increasingly serious injuries from auto accidents raise claim payouts. Your own record and location count as well. A claim, a ticket, an added driver, or a move to a costlier ZIP code can push your renewal up on top of the market trend.

The trend is mixed. Insurify’s data shows Illinois averages falling through 2025, and MyStateline reports one 2026 analysis that projected a decrease of about 4.26%. But Insurify’s mid-2026 report shows rates up 4.1% in the first half of 2026 and projects a 5.6% rise for the full year. CoverageAdvisor’s review of 103 filings from the nine largest carriers found prices up about 2.5% since mid 2023, and notes State Farm, the biggest insurer in Illinois, has held its rates mostly flat. Which carrier you have matters as much as the market.

Illinois car insurance requirements

Illinois requires bodily injury liability of $25,000 per person and $50,000 per accident, and property damage liability of $20,000, according to Finhabits. Medical payments coverage is optional and pays your medical expenses regardless of fault. Finhabits warns that Illinois minimum limits often leave drivers financially exposed after a serious crash, so higher liability limits are worth pricing.

How to lower car insurance in Illinois

1. Compare quotes from at least three insurers, since the cheapest company varies by driver profile. Finhabits names Erie, State Farm, and GEICO as competitive starting points.
2. Ask about discounts, including bundling auto with home, insuring multiple vehicles, and safe driver programs. Availability varies by state and insurer.
3. Consider paying in full. ABC7 Chicago’s report suggests paying your full bill instead of installments can cut costs.
4. Check your vehicle’s theft exposure. Some models are more expensive to insure in areas with high theft rates.
5. Review coverage after life changes, and raise your deductible only if you could cover it from savings.
