South Dakota sits in the Midwest and ranks 17th of 51 for car insurance cost. The main driver is hail and severe plains storms — insurers price that risk straight into your premium. 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.
