The most expensive state for car insurance — plus what it costs in every state

But the high cost of car insurance can depend on the state you live in (see the chart below for average premiums by state), with Maine often being the cheapest and Louisiana the most expensive. Louisiana’s high rates are largely due to its higher crime rate, frequent extreme weather and growing traffic density, while Maine, a state with low population density, has the lowest amount of uninsured drivers and a lower risk of accidents, says Andrew Hurst, auto insurance expert at Policygenius.

In general, states with cheaper car insurance may have lower levels of required car insurance, more insurance company competition, lower crime rates, lower rates of uninsured drivers, fewer total claims from drivers, drivers who overall drive fewer miles and/or less extreme weather.  “A rural state with little crime, many car insurers and not much extreme weather will likely pay less than a largely urban state with many car insurance claims, few insurers and many weather-related claims for flooding and hail,” says Les Masterson, insurance analyst with Carinsurance.com.  (See the lowest car insurance rates you can qualify for here.)

It’s also important to consider whether you are in a no-fault state: “No-fault states (there are 12) — [this] means that insurance companies cover their members’ injuries and damages instead of having the at-fault driver’s coverage pay — often lead to higher rates,” says Masterson. These include Florida, Michigan, New Jersey, New York, Pennsylvania, Hawaii, Kentucky, Massachusetts, Minnesota, North Dakota and Utah. Litigious states also get handed higher rates, as insurers price against litigation. “If a policyholder makes a claim and isn’t satisfied with it, they may take their insurance company to court. This process can be expensive, creating the potential for higher expenses and losses for insurance companies,” says Hurst. In places where rate setters have judged the population to be more litigious, rates may be higher.

The number of uninsured drivers can also be a big driver in rates, experts say. Indeed, Louisiana and Florida, which frequently land near the top of lists of the most expensive states to insure your car, have a lot of uninsured drivers, which creates a feedback loop: when there’s a large number of uninsured drivers, other drivers are more likely to carry more forms of insurance against them, explains Hurst: “This increases the likelihood of a single insurer paying more settlements, meaning that insurer will file for higher rates to cover expected losses,” says Hurst. Insurers also price against litigation and if a policyholder makes a claim and isn’t satisfied with it, they may take their insurance company to court. “This process can be expensive, creating the potential for higher expenses and losses for insurance companies. In places where rate setters have judged the population to be more litigious, rates may be higher,” says Hurst. Michigan, another state that has high rates, also faces this problem, Hurst says, and it “requires high personal injury protection coverage that often results in high settlements for insurance providers,” he adds, when explaining its high rates. (See the lowest car insurance rates you can qualify for here.)
