Joliet Car Insurance Rates by Company
Comparing quotes across insurers is the most powerful way to lower your insurance costs in Joliet. Rates can vary by hundreds of dollars per year for the same driver and the same coverage level. AAA (Auto Club Group) consistently offers some of the most competitive rates in the greater Chicago area, but availability requires membership.
| Insurance Company | 6-Month Premium | Monthly Cost |
|---|---|---|
| AAA / Auto Club Group Cheapest | $541 | $90 |
| State Farm | $550 | $92 |
| Travelers | $720 | $120 |
| Progressive | $750 | $125 |
| Allstate | $850 | $142 |
These rates reflect full coverage (liability, comprehensive, and collision) for a typical Illinois driver with a clean record and good credit. Your specific rate will vary based on your vehicle, driving history, age, and ZIP code within Joliet.
AAA and State Farm offer nearly identical pricing in Joliet, but AAA requires annual membership. If you're not already an AAA member, State Farm is the best option among easily accessible national carriers — and its local agents throughout Will County are highly rated for customer service.
Average Car Insurance Cost in Joliet
Joliet drivers pay an average of $1,197 per year for car insurance, working out to $599 every six months or about $100 per month. That's about 7% higher than the Illinois state average of $1,120 per year, though it's still meaningfully lower than the national average of $1,548.
| Location | Annual Rate | 6-Month Rate | Monthly Rate |
|---|---|---|---|
| Joliet, IL | $1,197 | $599 | $100 |
| Illinois Average | $1,120 | $560 | $93 |
| National Average | $1,548 | $774 | $129 |
Joliet's slightly elevated rates compared to the Illinois average reflect its location at the intersection of major interstates — I-55, I-80, and I-355 all converge near the city. That traffic volume translates to more accidents and higher claim frequencies, which insurers factor into local pricing.
Factors Affecting Car Insurance Rates in Joliet
High-Traffic Interstate Corridors
Joliet is positioned at one of the busiest highway interchanges in Illinois. Commuters heading into and out of Chicago regularly pass through the city, creating significant congestion on I-55 and I-80. Higher traffic density means more collisions, and more collisions mean higher insurance costs for all Joliet drivers — regardless of how carefully you drive.
If you commute primarily on surface roads and avoid the I-55/I-80 interchange, some insurers' telematics programs can reward you with discounts of up to 20-30% for low-risk driving habits. Ask your insurer about usage-based insurance options.
Driving Record Impact
Violations significantly increase costs in Joliet. A DUI conviction jumps the annual average to $2,589 — a $1,392 increase. Reckless driving is even worse at $2,729 per year. A speeding ticket adds about $240 per year on average. A clean record is your most valuable insurance asset.
Credit Score
Illinois allows credit-based pricing for insurance. Joliet drivers with very poor credit (300-579) pay an average of $2,404 per year, while those with exceptional credit (800-850) pay just $1,058 — a difference of $1,346 annually. Even improving from poor to fair credit saves about $444 per year.
Age-Based Rate Differences
Joliet's youngest drivers face dramatically higher rates: teenagers average $4,823 per year, compared to $1,031 for drivers in their 50s. The biggest drop happens when a teen turns 20 — rates fall by about 65% on average. Adding a teen driver to your policy will significantly increase your premium regardless of which insurer you choose.
Vehicle Theft in Will County
Will County sees above-average auto theft rates compared to rural Illinois, which can push comprehensive coverage premiums higher. Parking in well-lit areas, installing anti-theft devices, and choosing a vehicle with a lower theft rate can help reduce your comprehensive coverage costs.

Illinois Minimum Car Insurance Requirements
Illinois is an at-fault state — the driver who causes an accident is responsible for paying for damages. Illinois also mandates uninsured motorist coverage, which provides protection against the approximately 12% of Illinois drivers who carry no insurance.
| Coverage Type | Illinois Minimum | Recommended |
|---|---|---|
| Bodily Injury (per person) | $25,000 | $100,000 |
| Bodily Injury (per accident) | $50,000 | $300,000 |
| Property Damage Liability | $20,000 | $100,000 |
| Uninsured Motorist (per person) | $25,000 | $100,000 |
| Uninsured Motorist (per accident) | $50,000 | $300,000 |
Illinois's $20,000 property damage minimum is dangerously low in today's market. The average new vehicle costs over $48,000. If you total someone's car and your PDL limit is exhausted, you're personally responsible for the remainder. We recommend at least $50,000-$100,000 in property damage coverage.

Frequently Asked Questions
AAA/Auto Club Group and State Farm offer the most affordable car insurance in Joliet, with six-month full coverage premiums starting around $541-$550 ($90-$92 per month). However, AAA requires membership. Among easily accessible national carriers, State Farm consistently delivers the best rates in the Will County area. Always get quotes from multiple insurers since rates vary significantly based on your personal profile.
Joliet's location at the intersection of several major interstates (I-55, I-80, I-355) results in higher daily traffic volumes and accident frequency compared to smaller Illinois cities. Insurers use local claims data to set rates, and higher accident frequency in a zip code translates to higher premiums for everyone in that area — regardless of individual driving history.
Illinois requires minimum liability coverage of 25/50/20: $25,000 bodily injury per person, $50,000 per accident, and $20,000 property damage. Illinois also mandates uninsured motorist coverage at the same 25/50 bodily injury limits. Illinois is an at-fault state, so the driver who causes the accident is responsible for all damages.
Adding a teenage driver to a Joliet policy typically increases the premium substantially. Teenagers in Joliet pay an average of $4,823 per year for their own policy, but adding them to a parent's policy is usually less expensive. Good student discounts (typically B average or better), defensive driving courses, and choosing a safe, modestly-priced vehicle can all help reduce the impact on your premium.
No — Illinois only requires liability and uninsured motorist coverage. Comprehensive and collision are optional unless your vehicle is financed or leased, in which case your lender will require them. However, given the theft rates in Will County and the severe Illinois winters that can damage vehicles, most Joliet drivers benefit from carrying full coverage, especially on vehicles worth $10,000 or more.
