Illinois car insurance requirements explained
Illinois requires drivers to have liability insurance with limits of at least 25/50/20. You also need uninsured motorist (UM) coverage matching your liability limits. Illinois’ requirements are similar to those in other states, though the UM requirement is less common.
But UM can be valuable, because about 16% of Illinois drivers are uninsured, according to the Insurance Information Institute.[1]
Illinois bodily injury liability insurance requirements
Illinois drivers need at least $25,000 per person and $50,000 per accident of bodily injury liability coverage. That’s similar to limits in many other states. Bodily injury liability coverage helps pay for injuries you cause to others in an accident, up to your policy limits.
For example, if you injure two people in an accident, your policy would pay up to $25,000 for each person, up to the $50,000 per accident limit.
Illinois property damage liability insurance requirements
Illinois drivers must have at least $20,000 of property damage liability coverage. Property damage liability coverage helps pay for damages you cause to others’ property in an accident.
For example, if you cause an accident that totals the other driver’s $40,000 vehicle, your policy would cover up to $20,000. You’d potentially have to pay the remaining $20,000 out of pocket.
Illinois uninsured/underinsured motorist (UM/UIM) insurance requirements
While optional in many states, Illinois requires drivers to have uninsured motorist (UM) bodily injury coverage. Your UM limits must be the same as your bodily injury liability limits. UM helps cover your injuries if a driver without insurance hits you. If you purchase higher UM limits, Illinois law requires you to purchase underinsured motorist coverage as well.[2]

Are Illinois’ car insurance requirements sufficient for most drivers?
Illinois’ minimum car insurance requirements satisfy state law, but they may not provide sufficient financial protection in a serious accident. For example, if you cause an accident involving a new or expensive vehicle, you could easily exceed your policy limits. You’d be responsible for paying any remaining costs out of pocket.
The table below shows Illinois’ minimum car insurance requirements.
Coverage Type | Illinois Minimum Requirement |
|---|---|
| Bodily injury liability | $25,000/$50,000 |
| Property damage liability | $20,000 |
| Uninsured motorist bodily injury | $25,000/$50,000 |
| Underinsured motorist coverage | Required when UM limits exceed $25,000/$50,000 |
| Collision | Not required |
| Comprehensive | Not required |
Other car insurance requirements to be aware of in Illinois
Illinois law doesn’t require collision or comprehensive coverage. But if you lease or finance your vehicle, your lender may require both coverages to protect its investment. The exact coverage limits depend on the terms of your loan or lease agreement.
The state of Illinois follows an “at-fault” or “tort” insurance system. Under an at-fault system, the person at fault for an accident is responsible for the other driver’s property damages and injuries.
How Illinois’ car insurance requirements influence rates
The average cost of Illinois car insurance is $83 per month for liability-only coverage and $162 per month for full coverage. That’s typically slightly cheaper than the national monthly averages of $98 and $187.
Illinois’ minimum 25/50/20 requirements are similar to those of many other states, which explains why liability rates are close to the national average. Purchasing additional coverage, like collision or comprehensive insurance, usually costs more than liability coverage because the insurer takes on more risk.
When choosing your car insurance limits in Illinois, it’s a good idea to consider how much coverage you need. For example, if you cause $25,000 in vehicle damage in an accident, minimum property damage liability insurance would cover only $20,000. But you can purchase higher limits and additional coverage for more financial protection.
