Average cost of car insurance Illinois

While full coverage is more expensive than minimum liability, the extra protection is worth it for most drivers. Liability-only policies cover damage you cause to others, but not your own car. Full coverage adds collision and comprehensive protection, covering accidents, theft, weather, and other risks.

In Illinois, the average cost of full coverage is $363 less compared to the national average.

We recommend carrying at least 100/300/100 in coverage – $100,000 for bodily injury per person, $300,000 per accident, and $100,000 in property damage liability. These limits provide stronger protection in serious accidents that could otherwise exceed state minimums.

What is full coverage car insurance?

Full coverage car insurance includes bodily injury liability and property damage liability coverage, as well as comprehensive and collision coverage. Collision insurance covers your vehicle if it’s damaged or destroyed in an accident, while comprehensive insurance provides protection against damage that is caused by something other than collisions, such as hail or theft.

If you lease or finance your car in Illinois, your lender may ask you to purchase collision and comprehensive insurance beyond the state-mandated liability coverage.

The bottom line on saving and staying protected

Everyone wants to save on car insurance, but skimping on coverage can leave you with big bills after an accident.

The best approach is to balance affordability with protection. Always compare quotes from at least three companies to find the cheapest car insurance in Illinois.

Methodology

Insure.com gathered data from Quadrant Information Services to get car insurance rates in Illinois. The rates are based on a sample profile of a 40-year-old male and female driving a Honda Accord LX with a good insurance score and no violations on record for a full coverage insurance policy with limits 100/300/100 and $500 comprehensive and collision deductibles.

We analyzed 53,409,632 insurance quotes from 170 insurance companies across 34,588 ZIP codes nationwide.

To determine car insurance rates for high-risk drivers with a history of traffic violations, we used a sample profile of a 40-year-old male and female driver who own a Honda Accord LX.

We also used sample profiles of drivers from different age groups: Teen drivers (Age 16-19), young drivers (Age 20-24), adult drivers (Age 25-60) and senior drivers (Age 65-75)

We determined the premiums for a high-risk driver with the following incidents applied

  1. 1 At-fault property damage accident over $2K
  2. 1 At-fault property damage accident under $2K
  3. At-fault bodily injury accident
  4. Poor credit
  5. DUI/DWI first offense
  6. Speeding 30+ over limit
  7. Speeding ticket 1-10 MPH over limit
  8. Speeding ticket 11-29 MPH over the limit

These are sample rates, and your exact rates may vary.
