Car insurance rules in Illinois

Illinois requires drivers to carry at least $25,000 of bodily injury liability per person, $50,000 per accident and $20,000 of property damage liability, often written 25/50/20. It also requires uninsured motorist coverage ($25,000 per person, $50,000 per accident).

These are legal minimums, not a recommendation: a serious crash can cost far more, and anything above your limits is yours to pay.
