Why Is Car Insurance Expensive in Illinois?
Several factors drive higher insurance costs in Illinois, especially in the Chicago metro area:
1. High Vehicle Theft Rate
Chicago has one of the highest auto theft rates in the U.S. The Chicago metro area consistently ranks among the top metropolitan areas for vehicle theft, which increases comprehensive insurance costs statewide.
2. Severe Weather Exposure
Illinois faces significant weather risks including severe winter storms, ice, tornadoes (spring through early summer), and occasional flooding. Comprehensive claims for hail, wind, and winter weather damage are common. Illinois is part of “Tornado Alley,” with peak severe weather occurring from March through June.
3. Uninsured Driver Rate
Approximately 12% of Illinois drivers lack insurance, per Insurance Research Council data. This increases UM/UIM claim costs for insured drivers and raises everyone’s premiums.
4. Urban Congestion and High Accident Rates
Chicago is the third-largest city in America with notoriously heavy traffic. More vehicles on the road mean more accidents, which translates to higher claim costs and premiums.
5. High Medical and Repair Costs
Illinois has above-average medical care costs and vehicle repair expenses. When accidents happen, insurers pay more for hospital bills and body shop work—costs that get passed on to policyholders.
6. At-Fault Insurance System
Illinois is an at-fault (tort) state, meaning the driver who causes an accident is responsible for damages. While this can mean lower premiums than no-fault states for some drivers, it also means lawsuits are more common, increasing overall costs.
Illinois Car Insurance Costs by Area
Where you live in Illinois dramatically affects your premium. Here are average annual full-coverage rates by area:
| Area/ZIP Code | Avg. Annual Full Coverage | vs. State Avg. | Key Cost Factors |
| Naperville (60540) | $1,700–$2,000 | -10–15% lower | Suburban, lower crime |
| Evanston (60202) | $2,000–$2,400 | Near average | Suburban density, proximity to Chicago |
| Springfield (62704) | $1,500–$1,800 | -20–25% lower | Lower density, fewer claims |
| Champaign (61801) | $1,400–$1,700 | -25–30% lower | College town, lower theft |
| Chicago – Lincoln Park (60614) | $2,400–$2,800 | +20–30% higher | Urban density, theft rates |
| Chicago – South Side (60621) | $2,800–$3,400 | +40–50% higher | Higher crime, accident rates |
| Chicago – Loop (60601) | $2,600–$3,000 | +30–40% higher | Urban core, high density |
| Rockford (61101) | $1,600–$2,000 | -10–15% lower | Mid-size city, moderate rates |
Moving from a high-rate Chicago ZIP code to a suburban area could save $500–$1,000+ annually.

8 Ways to Lower Your Illinois Car Insurance
- Shop around and compare quotes.
Different insurers weigh factors differently. Getting 5+ quotes can reveal savings of $500–$1,500/year. Erie Insurance consistently offers among the lowest rates in Illinois.
- Increase your deductibles.
Raising your collision and comprehensive deductibles from $500 to $1,000 can reduce premiums 15–25%. Only do this if you can afford the higher out-of-pocket cost.
- Bundle home and auto.
Multi-policy discounts typically save 10–20% on both policies. This can mean $300–$500 in annual savings.
- Maintain a clean driving record.
One speeding ticket can increase your premium significantly. Accidents can nearly double your rate. Safe driving pays off.
- Ask about all available discounts.
Common discounts include: good student (for teens), defensive driving course, low mileage, anti-theft device, payment in full, paperless billing, military/veteran, and professional association memberships.
- Consider usage-based insurance.
Programs like Progressive’s Snapshot or State Farm’s Drive Safe & Save can reduce premiums 10–30% if you’re a safe, low-mileage driver.
- Review your coverage annually.
As your car ages, you may not need as much comprehensive/collision coverage. For vehicles worth under $5,000, the premiums may exceed potential payouts.
- Improve your credit score.
Illinois insurers use credit-based insurance scores. Improving your credit from “poor” to “good” can reduce premiums 20–40%.
Liability vs. Full Coverage: What’s Included
| Coverage | State Minimum | Full Coverage | Typical Use Case |
| Injuries you cause to others | $25K/$50K limits | 100/300 or higher | Essential asset protection |
| Property damage you cause | $20,000 limit | Higher limits (50K–100K+) | Protects against lawsuits |
| Your car (crash damage) | Not covered | Collision covers minus deductible | Financed/leased vehicles, newer cars |
| Your car (theft, weather) | Not covered | Comprehensive covers minus deductible | High-theft areas, severe weather zones |
| Your medical expenses | Not included | MedPay (optional, recommended) | Covers your injuries regardless of fault |
| Uninsured/Underinsured Motorist | UMBI mandatory (25/50) | Match to liability limits | Critical with 12% uninsured rate |
Illinois Insurance Requirements Explained
What Does 25/50/20 Mean?
Illinois’s minimum liability limits are expressed as 25/50/20:
- $25,000 for bodily injury to one person
- $50,000 for total bodily injury per accident (multiple people)
- $20,000 for property damage per accident
Why Minimum Coverage Often Isn’t Enough
Consider these realities: average new car price exceeds $48,000 (far above the $20K property damage limit), and average hospital stays can cost $13,000+ per day. If your liability limits are exhausted, you’re personally responsible for the remainder. Most insurance experts recommend at least 100/300/100 coverage to adequately protect your assets.
Medical Payments Coverage (MedPay) in Illinois
Unlike no-fault states, Illinois doesn’t require PIP. Traditional PIP is not available for purchase in Illinois. However, insurers offer MedPay, which covers your medical expenses regardless of fault—no deductible required. MedPay limits commonly range from $1,000 to $50,000. It’s a cost-effective way to get no-fault medical coverage in Illinois.
