Cheapest car insurance for military families in Illinois

If you're an active member of the military or a veteran — or have an immediate family member who is — chances are you'll get a relatively cheap rate with USAA, a company that isn't available to the general public.

Because of that restriction, USAA isn't ranked with the others, but it was among the cheapest five auto insurance options for 5 of the 70 driver profiles we examined.

Minimum auto insurance limits required in Illinois

Illinois law requires residents to carry liability insurance, including uninsured/underinsured motorist bodily injury coverage (UMBI), in the following amounts:

  • $25,000 bodily injury liability per person.

  • $50,000 bodily injury liability per incident.

  • $20,000 property damage liability per incident.

  • $25,000 UMBI per person.

  • $50,000 UMBI per incident.

Liability car insurance covers the cost of any damage, injuries or deaths you cause in a car accident, up to your policy’s predefined limits.

Uninsured motorist coverage will cover expenses from injuries or damage after an accident with a driver who doesn’t have car insurance. Underinsured motorist coverage will cover the same expenses if you’re hit by a driver with some car insurance, but not enough to cover all costs from the crash.

Personal injury protection will cover your medical bills and expenses if you’re injured in a car crash, up to your policy limits, no matter whose fault it was. Depending on your state, PIP may also pay for:

  • Lost wages if you’re unable to work due to injuries from an accident.

  • Services you can no longer perform, like house cleaning or child care, because of your injuries.

  • Funeral costs if an accident-related injury leads to death.

  • A small death benefit as a cash payout.

Even though this will be enough to drive legally, you may want more than the minimum requirements. Imagine causing a crash and totaling another person’s car, for instance. The damages could easily top your $20,000 liability limit, and the remaining balance would have to come out of your pocket.

The Illinois secretary of state randomly selects registered vehicles and requires their owners to prove they have insurance via questionnaire. Residents who fail to fill out the form or who report they don’t have insurance will have their license plates suspended.

Alternative car insurance in Illinois

High-risk drivers who are denied car insurance on the voluntary market because of prior crashes, DUIs, poor credit or other factors can seek coverage through the Illinois Automobile Insurance Plan.

METHODOLOGY

For our “good driver” profile, NerdWallet averaged insurance estimates for single male and female drivers with good credit and no tickets or violations. The analysis included 5-10 of the largest insurance companies in each state; smaller insurers were also included when rates were available. Liberty Mutual and its subsidiaries were excluded from our analysis as rates were not available.

For full coverage policies, we used the following coverage limits:

  • $100,000 bodily injury liability per person.

  • $300,000 bodily injury liability per accident.

  • $50,000 property damage liability per accident.

  • $100,000 uninsured motorist coverage per person.

  • $300,000 uninsured motorist coverage per accident.

  • Collision coverage with a $1,000 deductible.

  • Comprehensive coverage with a $1,000 deductible.

In states where required, minimum additional coverages were added. Some policies include additional coverages at the insurer’s discretion.

We used a 2021 Toyota Camry LE for all drivers and assumed 12,000 annual miles driven.

We analyzed rates for drivers 20 to 70 years old in ten-year increments. For the average cost of full and minimum coverage in each state, we looked at 35-year-old drivers.

We used the same assumptions for all other driver profiles, with the following exceptions:

  • For drivers with minimum coverage, we adjusted the numbers above to reflect the minimum required coverage by law in the state.

  • We changed the credit tier from “good” to “poor” as reported to the insurer to see rates for drivers with poor credit.

  • For drivers with one at-fault crash, we added a single at-fault crash that happened six months ago, resulting in $10,000 in property damage and no bodily injury claim.

  • For drivers with a DUI, we added a single drunken driving violation that happened six months ago.

We looked at 35-year-old drivers to find the cheapest company overall, the cheapest company for minimum coverage and the cheapest company for drivers with poor credit in states where credit history is used to price rates. We looked at 20-year-old drivers to find the cheapest company for young drivers.

These are rates generated through Quadrant Information Services. Your own rates will be different. Some insurance companies included in this article may have made changes in their underwriting practices and no longer issue new policies in your state.
