Why rates vary so much by state
The gap between Hawaii ($1,446/year) and Florida ($4,848/year) isn't random — it reflects how differently states regulate insurance, how often accidents and severe weather occur, and how litigious local court systems are. Every variable that affects an insurer's expected payout is built into the price you see.
State regulation is the biggest lever. Hawaii is one of only three states that prohibits credit scoring and also limits what insurers can charge based on age. That removes two factors that typically inflate premiums, which is the main reason it sits at the bottom of the rankings despite being an island state with limited competition.
Litigation climate drives Florida, Michigan, and Louisiana. These three states consistently rank in the top five most expensive because each has a legal or regulatory environment that increases what insurers pay out on claims. Florida had a well-documented attorney fee abuse problem that drove carriers out of the market. Michigan until recently required unlimited personal injury protection. Louisiana has among the highest bodily injury claim costs in the country. High claim costs flow directly into premiums.
Urban density amplifies everything. States with one dominant metro — Nevada (Las Vegas), New York, Delaware — tend to have higher statewide averages than their geography would otherwise suggest, because most of their insured population lives in a high-theft, high-accident corridor. The state average masks the difference between rural and urban ZIP codes, which can be 40–80% even within a single state.
Weather matters, but not as much as you'd think. Hail and tornado corridors in Kansas, Oklahoma, and Nebraska push comprehensive coverage costs up, but these states are still mid-table because bodily injury claims — not vehicle damage — drive the biggest rate differences.
Not sure what coverage you actually need?
Most drivers either over-insure or leave themselves exposed. The Coverage Calculator walks you through your specific situation — car value, finances, driver profile — and tells you exactly what to buy and what to skip.

The averages above are statewide full-coverage benchmarks — they reflect what a typical driver pays across all carriers in that state. Your actual rate depends on your ZIP code, driving record, vehicle, and which carrier you choose. Within any state, rates between carriers can vary by 50–100% for the same driver.
