Yes, under Illinois law all drivers are required to carry liability coverage insurance. 625 Ill. Comp. Stat. 5/7-601(a). Drivers must carry liability coverage of at least $25,000 per person for injury or death, at least $50,000 for injury or death of two or more people, and at least $20,000 for property damage of another. 625 Ill. Comp. Stat. 5/7-203. A driver that fails to comply with these laws may have their license plates suspended. 625 Ill. Comp. Stat. 5/7-601.
Illinois also requires that drivers obtain uninsured motorist coverage with limits that are equal to your bodily injury liability coverage ($25,000); however, this does not cover property damage. 215 Ill. Comp. Stat. 5/143a. Uninsured motorist coverage will help cover injuries to you or your passengers if you are involved in an accident with an uninsured driver.
