Affordable coverage for Illinois drivers

Drivers in Illinois are required to carry minimum coverage car insurance, which includes bodily injury and property damage liability coverage, as well as liability coverage for uninsured motorists.

Minimum coverage insurance in Illinois is abbreviated as 25/50/20, which includes:

  • $25,000 in bodily injury liability coverage per person
  • $50,000 in bodily injury liability coverage per accident
  • $20,000 in property damage liability coverage.

Purchasing minimum coverage insurance means you will pay the lowest rate. However, drivers are encouraged to purchase coverage beyond the minimum requirement. Car accidents can be expensive, and if your policy does not cover the full cost of an accident, you are responsible for paying the rest out-of-pocket.

How to get cheap car insurance in Illinois

If you are looking for the cheapest auto insurance in Illinois, finding an affordable carrier is important. However, there are several other ways that drivers can get a low rate. Here are some alternative ways to do this:

  • Shop around: Instead of settling for the first provider you find, do some research to identify a few car insurance companies that have the coverage and discounts you are looking for.
  • Compare rates: Get quotes from several insurance providers and compare them to see which company can offer the lowest-priced policy.
  • Take advantage of discounts: Look for insurance companies that offer discounts you qualify for. The more discounts you can take advantage of, the cheaper your premium will be.
  • Pay in full: If you can afford to pay your annual premium upfront and in full, you can probably save some money on your policy.
  • Raise your credit score: In Illinois, car insurance companies will use your credit score to price your insurance. Improving your credit score can help you get a lower rate.
  • Increase your deductible: If you can afford a higher out-of-pocket cost, consider raising your deductible. The savings are not significant, but it will lower your premium slightly.
