Illinois minimum liability is 25/50/20: $25,000 per person bodily injury, $50,000 per accident and $20,000 property damage. Illinois is an at-fault state with no PIP requirement, but mandates both UM and UIM coverage at matching limits. Every minimum policy in Illinois covers uninsured and underinsured drivers.

The average cost of car insurance in Illinois ranks 13th most affordable nationwide because rural downstate regions carry low traffic risk and the state has a competitive insurer market. Chicago's density pushes the statewide average higher than comparably rural states, but the overall mix keeps Illinois well below the national average. Illinois uses a UM/UIM mandate rather than a PIP requirement, which keeps baseline costs lower.

Minimum coverage averages $50 a month statewide; full coverage averages $99 a month, a $49 a month ($588 a year) gap. With GEICO, the gap is $38 a month ($31 minimum versus $69 full coverage). The full coverage benchmark is 100/300/100: $100,000 per person bodily injury, $300,000 per accident and $100,000 property damage, plus comprehensive and collision coverage with a $1,000 deductible. An at-fault accident causing $40,000 in bodily injury for one person exceeds Illinois's $25,000 per-person minimum by $15,000; the 100/300/100 benchmark covers the full amount.
