How to think about auto insurance in Illinois: what to buy and why (2026)

Updated 2026-05-21 Source: PolicyChat Rate Authority Methodology

For most Illinois drivers, $300K/$300K liability is the right starting point. The math: most carriers price the jump from $100K/$300K to $300K/$300K at $8-18 a month, and the protection difference is real. A serious bodily-injury claim crosses $100K fast.

How to think about this

The threshold to think harder is $500K in assets. Past that point, $300K/$300K plus a $1M umbrella is the standard package; the umbrella runs $150-300 a year and requires you to first carry $250K/$500K underlying. Below $500K in assets, $300K/$300K alone is plenty.
