Maine’s residents pay just $949 a year for full coverage car insurance, making it one of the cheapest states. Louisiana’s drivers face much steeper costs at $2,734 yearly – about 48% more than what most Americans pay.
The numbers tell an interesting story. Maine leads the pack as the most affordable state, and Idaho comes in close behind at $992 per year. A driver’s location plays a huge role in their car insurance rates. The most expensive states’ rates can triple what drivers pay in cheaper areas. These regional price differences are a vital part of finding the best insurance deals, especially if you’re moving or buying a new car.
This piece dives into why some states have better insurance rates than others. You’ll find out what drives these prices up or down and how to get cheaper auto insurance no matter where you live. The comparison between states with the lowest and highest premiums will help you streamline your insurance costs in 2025.
The national picture: What car insurance costs in 2025

Car insurance costs have hit record highs across America in 2025. Full coverage car insurance now costs between $2,101 and $2,677 per year, based on different sources. The increase has slowed down to 7.5% in 2025 compared to 16.5% in 2024.
Average cost for insurance on a car in the U.S.
Car insurance prices swing wildly from state to state. Nevada ($3,639), Florida ($3,864), and Michigan ($3,193) rank as America’s most expensive states for car insurance in 2025. The best deals come from Vermont ($1,489), Idaho ($1,442), and Maine ($1,631). These states’ premiums run about 40% lower than what most Americans pay.
How full coverage and minimum coverage differ
Full coverage policies give you much more protection but cost more. Minimum coverage policies cost about $807 yearly, making them 153% cheaper than full coverage insurance. The catch? Minimum coverage only gives you the basic liability protection your state requires.
California leads the change in 2025 by raising its minimum liability requirements. The state now requires $30,000 for bodily injury per person, $60,000 per accident, and $15,000 for property damage. These new limits replace rules that were 58 years old.
Why your ZIP code still matters more than you think
Your exact location affects your premium in a big way. Drivers with similar records might pay hundreds more just because they live in different ZIP codes within the same state. Insurance companies look at several local risk factors:
- Accident frequency: More crashes in your area mean higher premiums
- Crime rates: Vehicle theft and break-ins push costs up
- Weather patterns: Areas prone to floods often cost more to insure
Detroit drivers pay the highest city average at $5,300 yearly, while Raleigh residents enjoy rates of just $1,239. These stark differences show why your address plays such a vital role in your insurance costs.

Some regions in America offer cheaper auto insurance rates than others. Recent analysis shows these eight states are the cheapest states for car insurance in 2025:
1. Maine: Low population, low premiums
Maine leads the pack with average annual rates of $949. The state’s full coverage costs $1,631 per year, and minimum coverage is just $418. The state’s sparse population and rural setting mean fewer accidents and claims. This leads to lower premiums for Maine’s residents.
2. Idaho: Rural roads and fewer claims
Idaho takes second place with yearly premiums averaging $992. Drivers pay about $1,442 annually for full coverage, while minimum coverage costs $375. The state’s well-maintained roads and light traffic help keep rates budget-friendly. Boise’s residents enjoy rates 9% below the state average.
3. Vermont: Safe drivers and low crime
Vermont holds third place with an average yearly rate of $1,053. The Green Mountain State’s low crime rate and scattered population create less crowded roads with fewer accidents. Vermont’s rates are nowhere near the national average. The state’s low uninsured motorist rate of under 9% helps keep costs down.
4. Ohio: Competitive market keeps prices down
Ohio’s average yearly premium sits at $1,083. More than 275 insurance companies operate in the state. This competition gives drivers more choices and better rates. Ohio’s drivers pay about $39 monthly for minimum liability coverage—35% below national averages.
5. Wisconsin: Affordable rates and strong infrastructure
Wisconsin’s yearly average comes to $1,145. The state ranks fifth cheapest for auto insurance. Minimum coverage costs $454 and full coverage runs $1,921. Green Bay residents pay around $954 yearly while Milwaukee drivers see rates of $1,482.

7. Iowa: Low traffic and high safety
Iowa’s average premium reaches $1,215. The state ranked third least expensive for auto insurance in 2021, with drivers paying $725.30 on average. Low maintenance costs, light traffic, and quick commutes make Iowa an affordable choice.

Hawaii’s strict insurance rules don’t allow companies to use credit scores, gender, or age to set premiums. The state’s limited number of licensed drivers and good public transit help keep rates down.
Why some states are cheaper than others
Image Source: GOBankingRates
Car insurance prices vary dramatically between states due to four key factors that insurance companies use to set their rates.
State insurance laws and minimum coverage requirements
Insurance costs depend heavily on state regulations through rating restrictions and coverage requirements. Hawaii doesn’t allow insurers to look at credit scores, gender, age, or education when setting premiums. California has similar rules and bans gender, credit history, education, and occupation as rating factors. This means insurance companies can only look at driving records and vehicle types. States like Wyoming take a different approach and let insurers use almost any rating factor, which creates very different pricing structures.
Weather patterns and natural disaster risks
Natural disasters shape premium costs across America. Extreme weather cost the U.S. more than $92 billion in 2023 alone. Hurricanes, wildfires, and floods push rates higher in areas at risk. Florida’s insurance companies have pushed rates up because hurricanes keep getting stronger. States like Colorado have seen premiums jump by 50% due to increasing hail storms.
Population density and traffic congestion
Insurance rates tend to be higher in urban areas than rural ones. Companies look at how many cars are on the road to figure out risk. The logic is simple – more cars mean more chances for accidents. States like Maine and Vermont keep lower premiums because their smaller populations lead to fewer accidents and claims. The basic rule is clear – more vehicles on the road means higher accident risk and bigger premium costs.
Uninsured driver rates and local claim history
States where many drivers don’t have insurance pass these costs to insured drivers. About 14% of U.S. drivers (1 in 7) drive without proper insurance. This forces companies to raise rates for everyone else. Oklahoma and New Mexico had the highest uninsured motorist rates at 26.4%, which affects their premium costs by a lot. Maine and Wyoming have the lowest rates of uninsured drivers at about 6%. This helps keep their insurance costs among the lowest in the country.
States also control how much insurance companies can raise rates based on past claims.
How to find the best auto insurance prices in your state
Smart shopping helps you find cheaper car insurance, even in states with the lowest rates. You can save money in several proven ways.
Compare quotes from multiple providers
Getting at least three quotes from different insurance companies shows big price differences for similar coverage. The Insurance Information Institute suggests this as the minimum. You can speed up this process with online quote-comparison tools that show multiple options at once. Make sure coverages and deductibles match between quotes to compare prices accurately. State Farm, Allstate, and USAA offer some of the best rates nationwide. State Farm’s rates average $116 monthly for full coverage and $56 for liability-only policies.
Look for discounts based on your profile
Most drivers can get seven discounts on average. Your clean driving record could save you up to 30%. Students with “B” averages save up to 25%, and military members often get 15% off. A few hours in defensive driving courses can cut your premiums by 10-15%. New cars with advanced safety features are a great way to get discounts up to 40% on medical coverage.
Think over usage-based or low-mileage programs
Telematics programs watch your driving habits and reward safe behavior. Progressive’s Snapshot program helps drivers save $322 each year. Nationwide’s SmartRide gives up to 40% off for safe driving, and their SmartMiles program saves low-mileage drivers 25% compared to regular policies.
Bundle policies for extra savings
You can save up to $1,356 by putting your auto and home insurance with one company. Auto and renters insurance bundles save up to $834. Multiple cars under one policy can cut your premiums by about 20%. Bundling makes life easier with one bill and one account to manage.
Adjust your deductible and coverage levels
Your premiums drop 15-30% when you raise deductibles from $500 to $1,000. The math is simple – higher deductibles mean lower premiums but more out-of-pocket costs when you file claims. You can set comprehensive deductibles lower than collision deductibles without raising rates much.
Conclusion
Car insurance prices vary widely across states, and knowing the cheapest options helps drivers find better deals in 2025. Maine leads the pack as the most affordable state at $949 annually. States like Idaho, Vermont, and Ohio also offer great rates. The price gap becomes clear when you look at expensive states like Nevada or Florida, where drivers pay up to $3,600 for coverage.
Location plays a huge role in what you’ll pay, and there are good reasons for this. Maine’s low premiums stem from its sparse population. State laws shape pricing too – take Hawaii, which prohibits the use of credit scores and demographic factors in setting rates. Natural disasters and weather patterns push prices up in certain regions.
Smart drivers can find ways to save money, no matter where they live. Getting quotes from different companies often reveals surprising deals for similar coverage. You can cut costs by claiming discounts for good driving, bundling your policies, or joining usage-based programs. Playing with deductible amounts helps balance monthly payments against what you’ll pay after an accident.
The huge price gaps between states show why research matters when buying car insurance. While your zip code largely determines your premium, you can still save money by shopping around and customizing your policy. Understanding these regional differences helps you make smarter choices about coverage and save hundreds or thousands of dollars each year.
