Car Insurance in Illinois: 2026 Rates & Requirements

Illinois is one of the more insurance-affordable large states in the country, largely because it's a traditional at-fault (tort) state without the added PIP requirement that pushes up premiums in neighboring no-fault states like Michigan.

Minimum Insurance Requirements in Illinois

Illinois requires drivers to carry at least $25,000/50,000 in bodily injury liability (per person / per accident) and $20,000 in property damage liability. Illinois also requires uninsured/underinsured motorist coverage, at the same $25,000/$50,000 limits as bodily injury liability. Illinois is an at-fault (tort) state: the driver who caused the accident, through their liability coverage, pays for the other party's injuries and property damage. These are legal minimums, not a safety net for your own finances — most independent advisors recommend carrying meaningfully higher limits than the state requires, especially if you own a home or have savings to protect.

What Drives the Cost of Car Insurance in Illinois

The Chicago metro area drives most of the statewide average up: dense traffic, higher accident frequency, and elevated vehicle theft rates in and around the city push premiums well above what drivers in downstate Illinois typically pay for a similar profile. Illinois requires uninsured/underinsured motorist coverage as part of its minimum, which is worth understanding since not every state makes that mandatory. Winter weather - ice, snow, and the accident spikes that come with it - is another statewide factor that shows up in claims data every year.
