Where you live affects your car insurance premium more than almost any other factor besides your driving record. State-level minimum coverage requirements, population density, weather risk, litigation costs, and theft rates all combine to create some of the widest cost gaps in the country — drivers in the most expensive states can pay two to three times more than drivers in the cheapest ones for similar coverage. Multiple 2026 industry rate studies point to a consistent group of low-cost states. Here’s what’s driving those numbers and how to use them.
Vermont
Vermont shows up as the cheapest or near-cheapest state for car insurance across nearly every major 2026 rate study, with full-coverage premiums commonly cited in the $1,300–$1,700 per year range. Low population density, light traffic congestion, and a low rate of uninsured drivers all contribute to its consistently low averages.
Maine
Maine regularly ranks as the second- or third-cheapest state, with average full-coverage premiums typically falling between $1,500 and $1,800 per year. Like Vermont, its low traffic density and lower accident frequency help keep statewide averages down.
New Hampshire
New Hampshire is unique in that it’s one of the only states that doesn’t require drivers to carry auto liability insurance at all, though most drivers carry coverage anyway to meet financial-responsibility requirements after an accident. It consistently posts some of the lowest average premiums in the country.
Idaho
Idaho often ranks among the very cheapest states for both minimum and full coverage, with some 2026 analyses placing its full-coverage average near or below $1,500 per year. Lower repair costs and a less congested road network are commonly cited as contributing factors.
Ohio
Ohio is frequently cited as one of the more affordable larger states, with full-coverage averages generally under $1,800 per year — notably lower than other Midwestern states of similar population size.
Hawaii
Despite its geographic isolation, Hawaii consistently posts lower-than-average premiums, which several rate studies attribute to strict state insurance regulation and lower accident frequency relative to mainland states with comparable populations.
Why These States Are Cheaper
A few consistent factors separate cheap states from expensive ones:
- Lower population density generally means fewer accidents and less traffic congestion.
- Lower rates of uninsured motorists, which reduces the cost insurers pass on through uninsured-motorist coverage.
- State insurance regulation. Some states allow regulators more authority to review or limit rate increases.
- Lower litigation and medical-cost exposure, particularly in states without expansive no-fault personal injury protection requirements.
- Less severe-weather risk, since hurricane-, hail-, and flood-prone states see higher comprehensive claims.
By contrast, states like Florida, Louisiana, Nevada, New York, and Michigan consistently rank among the most expensive, largely due to a combination of severe weather exposure, high litigation costs, dense traffic, and in Michigan’s case, complex no-fault coverage requirements.
Rankings Vary by Source — Here’s Why
You’ll notice that different rate studies don’t always agree on the exact order of the cheapest states. That’s because each uses different sample driver profiles, vehicles, coverage limits, and data providers. Rather than treating any single ranking as definitive, use these studies to identify the general pattern — low-density, lower-litigation states tend to be cheaper — and then get an actual quote for your specific situation, since your individual rate depends far more on your driving record, age, vehicle, and credit profile than on state averages alone.
Check Your State’s Specific Requirements
Minimum coverage requirements and regulatory rules differ by state and can change from year to year, so it’s worth confirming current requirements directly through your state’s official insurance regulator before shopping for a policy, especially if you’re moving.

Bottom Line
If you live in or are considering moving to a high-cost state, the location-driven part of your premium isn’t something you can control directly — but shopping around, maintaining a clean driving record, and comparing quotes from multiple insurers still has an outsized effect on what you actually pay, regardless of which state you call home.
