Illinois sits in the Midwest and ranks 43rd of 51 for car insurance cost. Premiums stay lower thanks to lower catastrophe risk and fewer costly claims. Either way, the same coverage is quoted very differently between carriers, so what you personally pay comes down to who you buy from.

The levers that move your rate the most: bundling auto with home or renters; raising your deductible; asking about low-mileage and safe-driver discounts; comparing at least 3 carriers — the same driver is quoted hundreds apart. The biggest one is simply re-shopping at renewal — insurers raise rates on existing customers faster than they quote new ones, so loyalty quietly costs you.
