Car Insurance Rates by State: Full Ranking (2026)
Below is the complete ranking of all 50 states by average annual car insurance premium, from most to least expensive.
Why Car Insurance Rates Vary So Much by State
Several factors explain the dramatic differences in car insurance rates across states:
State insurance regulations: Some states allow insurers to use credit scores, while others prohibit it. No-fault states (like Michigan and Florida) tend to have higher premiums because of mandatory personal injury protection (PIP) coverage.
Uninsured driver rates: States with high rates of uninsured motorists — like Mississippi (29.4%) and New Mexico (24.5%) — see higher premiums as insurers spread the cost of uninsured motorist claims across all policyholders.
Weather and natural disasters: States prone to hurricanes (Florida, Louisiana), hail (Texas, Oklahoma), and flooding see more comprehensive claims, driving up rates.
Population density and traffic: Urban areas have more accidents, theft, and vandalism. States with large metro populations (California, New York, New Jersey) have higher rates.
Legal environment: States where lawsuits over auto accidents are more common (sometimes called 'judicial hellholes') see higher liability claim costs, which insurers pass on to policyholders.
Minimum coverage requirements: States that mandate higher minimum coverage (like Maine's 50/100/25) naturally have higher average premiums than states with lower minimums (like California's 15/30/5).
Methodology
This report uses data from the National Association of Insurance Commissioners (NAIC), the Insurance Information Institute (III), and state-level regulatory filings. Base rates reflect 2024 NAIC data, adjusted for 2025-2026 rate trends using approved rate filings from major insurers.
Profile assumptions: Rates are based on a 35-year-old driver with a clean record, good credit, and a 2022 mid-size sedan with full coverage (100/300/100 liability, $500 deductibles for collision and comprehensive).
National average: The $1,127 national average reflects minimum coverage rates. Full coverage averages approximately $1,895/year nationally.

Even in expensive states, you can lower your rate by: comparing quotes from 3-5 insurers, raising your deductible, bundling with home insurance, asking about all available discounts, and maintaining a clean driving record and good credit.
