Car Insurance in Illinois (2026): Costs, Minimums & Chicago Rates

Minimum Car Insurance in Illinois: 25/50/20 Plus Uninsured Motorist

Illinois law (625 ILCS 5/7-601) says no one may operate — or even keep a registration on — a motor vehicle designed for public roads unless it is covered by a liability policy. The minimum amounts come from 625 ILCS 5/7-203 and have applied to policies issued or renewed since January 1, 2015:

Two Illinois-specific details from the Illinois Department of Insurance (IDOI) are worth knowing. First, under 215 ILCS 5/143a-2, underinsured motorist coverage becomes mandatory as soon as you raise your uninsured motorist limits above 25/50. Second, insurers must offer uninsured motorist property damagecoverage, with a deductible no higher than $250 — useful if you drop collision on an older car but still want protection against an identified uninsured driver.

Is the minimum enough?The IDOI itself tells consumers that "the state minimums may not be enough to fully protect you from lawsuits." A $20,000 property damage limit will not replace many late-model SUVs, and the Insurance Research Council estimated that more than 16% of Illinois drivers were uninsured in 2022 (as cited by NerdWallet), which is exactly why the state makes UM coverage mandatory.

What Changed in 2026: SB 714 and Illinois Rate Review

You may have seen claims online that Illinois raised its minimums to 30/60/25 in 2026. That is not correct — the statute and the IDOI still list 25/50/20. The real 2026 change is about how rates are approved, not how much coverage you need.

Until now, Illinois was one of the only states where auto insurers could change prices without prior state review. On August 4, 2026, Gov. JB Pritzker signed Senate Bill 714. According to Capitol News Illinois and Repairer Driven News coverage of the signing:

• The IDOI gains authority to review auto rate filings and reject rates that are "excessive, inadequate or unfairly discriminatory."
• The rules apply to rates filed on or after July 1, 2027 — so 2026 renewals are not yet affected.
• Insurers must give 30 days' advance notice before renewal increases above 10%.
• Insurers may not pass out-of-state catastrophe losses onto Illinois policyholders, and the department can order rebates for overcharges.

What SB 714 did not do: Secretary of State Alexi Giannoulias had pushed a separate bill (SB 1486) to price policies on driving record instead of credit score or ZIP code, but the final law does not ban either factor. Illinois insurers can still use credit-based insurance scores, subject to the existing Use of Credit Information in Personal Insurance Act (215 ILCS 157/20), which bars insurers from denying, canceling, nonrenewing, or setting renewal rates solely on credit information.

Average Cost of Car Insurance in Illinois

Published Illinois averages vary widely because each company prices a different sample driver, vehicle and coverage level. Here are the most recent figures from four national rate studies:

The spread — roughly $99 to $205 a month for "full coverage" — is a good reminder that an average is not a quote. MoneyGeek, for example, found that moving from minimum liability to 100/300/100 limits with a $1,000 deductible raised its sample premium from $68 to $105 a month, while dropping the deductible to $0 pushed it to $143. In other words, deductible choice can move an Illinois premium more than liability limits do.

Rates have also been volatile. ValuePenguin's tracking of Illinois rate filings (data as of July 28, 2026) shows State Farm cutting rates 10.0% and Country Financial 8.0% so far in 2026, while Farmers raised rates 5.8%. Over five years, though, most carriers are still well up — for example Erie +93.2%, Farmers +86.6%, Liberty Mutual +63.9% and Allstate +58.3% — which is the backdrop to the SB 714 rate-review debate.

Car Insurance in Chicago, Illinois vs Downstate

Chicago is the single biggest pricing factor in Illinois. NerdWallet's September 2026 analysis puts the average full coverage premium in Chicago at $3,386 per year, versus $2,461 statewide. Even inside the city the gap is large: among Chicago's most populated ZIP codes, NerdWallet found averages from $3,167 in 60625 (Lincoln Square/Albany Park) to $3,830 in 60623 (Little Village/North Lawndale) for the same 35-year-old driver.

Source: ValuePenguin Illinois rate study, updated September 25, 2026 (full coverage, 30-year-old male).

The most expensive place ValuePenguin found was not Chicago itself but Dolton, a south suburb, at about $303 a month; the cheapest was Chenoa, east of Peoria, at about $167. The pattern is consistent: Cook County and its south suburbs cost the most, the collar counties sit in the middle, and central Illinois college and farm towns are the cheapest.

The Chicago market also looks different. IDOI data for 2024 shows the city of Chicago accounts for 13.8% of statewide auto liability premium, and non-standard carriers such as Direct Auto (3.18% city share vs 0.86% elsewhere) and Unique Insurance (2.54% vs 0.66%) write far more business in the city than downstate. For Chicago drivers, NerdWallet's cheapest average full coverage rates for a 35-year-old came from Progressive ($2,055/yr), Erie ($2,574), Travelers ($2,589), Mercury ($2,627) and Auto-Owners ($2,660).

Best Car Insurance in Illinois: Who Actually Insures Illinois Drivers

Illinois is home to two of the country's biggest auto insurers — State Farm (Bloomington) and Allstate (Northbrook/Glenview) — plus Country Financial, which started in 1925 as a farmer-run insurer tied to the Illinois Agricultural Association and is also based in Bloomington. According to the IDOI's 2026 Cost Containment Report, these were the largest writers of private passenger auto liability insurance in Illinois in 2025:

Market share tells you who is big, not who is cheap. Here is how the main Illinois options compare in 2026 studies:

• State Farm – The dominant Illinois insurer with a large local agent network. ValuePenguin found its minimum liability rate around $62/mo, and it cut Illinois rates 10% in 2026.
• Country Financial – Illinois-based, agent-sold, and strongest downstate. MoneyGeek found it cheapest for Illinois drivers with bad credit ($184/mo full coverage), and it appears in ValuePenguin's top five for full coverage ($158/mo).
• Travelers – Cheapest full coverage in NerdWallet's ($1,524/yr) and ValuePenguin's ($120/mo) 2026 Illinois studies.
• Erie – A regional insurer that writes auto in Illinois through independent agents; among the cheapest for minimum coverage in both NerdWallet ($31/mo) and ValuePenguin ($42/mo) data.
• Auto-Owners and Westfield – Midwestern regionals sold through independent agents. Westfield tied Erie for the cheapest NerdWallet minimum coverage rate ($31/mo); Auto-Owners earned MoneyGeek's top overall score in Illinois.
• GEICO and Progressive – MoneyGeek found GEICO cheapest overall ($31 minimum, $70 full); Progressive was NerdWallet's cheapest in Chicago and after a DUI.
• Allstate – Headquartered in the Chicago suburbs; NerdWallet found it among the cheapest for liability coverage after a DUI ($67/mo) and with poor credit ($41/mo).

Illinois Insurance Verification (ILIVS) and Penalties for Driving Uninsured

Under Public Act 100-0373, the Secretary of State runs the Illinois Insurance Verification System (ILIVS), which electronically checks registered vehicles against insurers' records. If your vehicle does not match an active policy, you receive a notice and must confirm coverage through your insurer or agent at ILIVS.com using the reference number on the letter. Ignore it, and your license plates are suspended.

• Driving uninsured: a fine of $500 to $1,000 for a first or second violation; a third or later violation is a business offense with a $1,000 fine (625 ILCS 5/3-707).
• Plate suspension: a first mandatory-insurance suspension ends once you buy coverage and pay a $100 reinstatement fee. A second suspension must be served for four months, plus the $100 fee (625 ILCS 5/7-606).
• Driving on suspended plates: the Secretary of State's suspension notice warns that the minimum fine is $1,000.
• Repeat offenders: after a third uninsured-driving conviction, you must file proof of financial responsibility (an SR-22) and keep it for three years.
• Crashes while uninsured: the Safety Responsibility law can suspend your license if you are in a reportable crash without insurance and cannot post security for the damages.

Illinois accepts electronic proof of insurance on a phone (625 ILCS 5/7-602). If you already have violations, a suspension or a DUI, see our Illinois SR-22 insurance guide.

Illinois Is an At-Fault State: What That Means After a Crash

Illinois has no personal injury protection (PIP) requirement. The at-fault driver's liability insurance pays the other side's medical bills and repairs, which is why your own policy's limits matter so much. Illinois uses modified comparative negligence (735 ILCS 5/2-1116): according to the IDOI, you can recover damages only if you are less than 50% at fault, and your payment is reduced by your share of the blame. If you are found 20% at fault, the other insurer may pay only 80% of your loss.

Because a minimum policy pays nothing toward your own injuries in a crash you cause, many Illinois drivers add medical payments coverage, and anyone with a financed or leased car will need collision and comprehensive. MoneyGeek notes Illinois ranked fourth nationally for vehicle thefts in 2023, which makes comprehensive coverage worth pricing even outside Chicago.

Liability Car Insurance in Illinois vs Full Coverage

"Liability-only" in Illinois still means 25/50/20 liability plus25/50 uninsured motorist coverage, so it is not quite the bare-bones policy it is in some states. It is a reasonable choice when your car is old and paid off. MoneyGeek's rule of thumb, using GEICO's Illinois pricing, is that the $468 a year extra for full coverage is hard to justify on a car worth less than about $1,500.

For a newer car, full coverage (liability plus collision and comprehensive) is usually required by your lender and is the only thing that pays to fix or replace your own vehicle. If you raise your UM limits for better protection, remember that Illinois then requires matching underinsured motorist coverage.

Illinois Rules on Cancellation, Nonrenewal and Switching Insurers

• First 60 days: an Illinois insurer may cancel a new policy for almost any reason while it reviews your risk.
• After 60 days: cancellation is limited to specific reasons such as nonpayment, fraud, a license suspension or revocation in the household within 12 months, or certain serious convictions within 36 months.
• Notice: at least 10 days for nonpayment and 30 days for any other reason. You may request an IDOI hearing at least 20 days before the cancellation date if you believe the cancellation was improper.
• Switching safely: the IDOI suggests asking an agent for a "non-bound application" so the new company confirms your price before you cancel your old policy.

If no company will accept you, the Illinois Automobile Insurance Planis the state's last-resort market. It is rarely used — the IDOI reports only 25 private passenger applications in 2025 — because most high-risk drivers find coverage from non-standard carriers first.

Illinois Car Insurance Quotes by Driver Type

• Teen and young drivers: the IDOI says the easiest and likely cheapest route is joining a parent's policy. Illinois can suspend drivers under 21 after two moving-violation convictions within 24 months (625 ILCS 5/6-206). NerdWallet's cheapest minimum coverage for 20-year-olds came from Westfield ($62/mo) and Erie ($67/mo).
• Seniors: Erie ($31/mo) and Westfield ($37/mo) had the lowest NerdWallet minimum coverage rates for 70-year-olds, and many insurers offer a discount for drivers 55 and older who complete an approved defensive-driving course.
• Drivers with tickets: ValuePenguin found Illinois rates rise about 23% after one speeding ticket and 52% after one at-fault accident. Three moving-violation convictions in 12 months can lead to a license suspension.
• DUI and SR-22 drivers: see the Illinois high-risk and SR-22 guide.
• No car of your own: see non-owner and temporary car insurance in Illinois.

How to Lower Your Illinois Car Insurance Bill

• Quote at least one regional carrier. Erie, Westfield, Auto-Owners and Country Financial repeatedly undercut national brands in 2026 Illinois studies, but they are mostly sold through local agents, so they may not appear in online-only comparisons.
• Check your deductible before your limits. MoneyGeek's Illinois data shows a low deductible can cost more than much higher liability limits.
• Protect your credit. Illinois still allows credit-based insurance scores. Insurify data cited by Axios in May 2026 showed Illinois drivers with excellent credit paying about $1,504 a year for full coverage versus $2,233 for drivers with poor credit.
• Ask for Illinois-listed discounts: good student (B average), low mileage (often under 7,500 miles a year), mature driver defensive-driving course, multi-car, auto/home bundle and anti-theft devices — all listed in the IDOI shopping guide.
• Never let coverage lapse. A lapse can trigger an ILIVS plate suspension and a $100 fee on top of higher future premiums.
