Every state has its own car insurance laws, and that's one reason why car insurance rates by state vary dramatically across the country. Another reason is that your location is chief among the factors car insurance companies use when setting rates.

Based on the number and severity, or cost, of car insurance claims within the area, insurers assign ZIP codes different risk levels. Insurers take into account the frequency of thefts, collisions and vandalism to gauge the likelihood of such incidents happening to drivers within the ZIP code. This is used as the base rate from which insurers calculate your premium.

Other pricing factors, such as your driving record, type of car you drive, how much coverage you buy and your age are then added into the calculation.

Key Highlights
  • Maine, New Hampshire and Virginia are the cheapest states for full coverage policy whereas South Dakota, Iowa and Wyoming are the cheapest for state minimum coverage.
  • Michigan, Louisiana and Nevada are the most expensive states for full coverage policy whereas Michigan, Connecticut and New York are the most expensive states for minimum car insurance coverage.
  • Vehicles stolen, fraudulent injury claims and reports of vandalism are some of the factors that can drive rates higher in your particular state.
  • Michigan ranks second in the country for uninsured drivers that is roughly 25.5% of drivers whereas in Nevada the uninsured rate is around 10.4%.

Auto insurance rates by state minimum and full coverage policy

Below you’ll see how states rank for a full coverage policy, as well as what the average cost is for bare-bones coverage. The difference in price is significant, as minimum coverage only pays for damage you do to others and their property.

In accidents that are your fault, your own car is not covered under a state minimum policy. Full coverage includes collision insurance, which pays for damage to your car in accidents you cause.

It also includes comprehensive insurance, which pays out up to the cash value of your car to repair or replace your car for damage due to fire, flooding, hail and animal strikes. Comprehensive insurance also covers theft. Liability limits under full coverage are higher than state minimums, so provide more financial protection. That’s why there is a significant price difference.

Which states have the lowest car insurance rates?

States that are more rural and have fewer drivers generally have lower car insurance rates, overall, because there are fewer accident claims. A states’ rate of uninsured drivers also plays a role in keeping costs low.

Other factors come into play, too for instance if the majority of drivers in a state have good credit, that can impact the state average, in states where it is legal to use credit when setting prices.

Finally, rates are typically lower in states that have a competitive market for car insurance, meaning there are many local, small-sized carriers as well as major insurance companies selling policies in that state.


Maine ranks 38th in the nation for population density, so that means it’s a state with relatively fewer drivers than others. In addition, Maine has a healthy car insurance market. Thanks to a competitive market, Maine consumers are paying less for auto insurance than consumers in nearly every other state, according to statements made by Insurance Superintendent Eric Cioppa.

Maine also has one of the lowest rates of uninsured drivers (4.9%) in the country. This lowers an insurer’s risk, which results in better premiums for everyone.

New Hampshire also qualifies as a low-population, rural state, so that helps keep its rates low, on average. It also nurtures a competitive market in that state laws require insurance companies to accept all drivers with clean records who apply for coverage.

Eireann Sibley of the state insurance commission says that the state also has many drivers that are retired, which may mean overall that many drivers are not commuting long distances, which cuts down on accidents.

Additionally, the state has a relatively high median income which may mean more drivers have chosen higher deductibles.


Ohio is not as rural as Maine and New Hampshire, but like those states, its rates are among the cheapest in the nation because of consumer choice in the market, with over 250 carriers offering car insurance.

"Strong competition helps produce some of the lowest rates in the country, and Ohio is fortunate to have many insurers offering a wide array of products giving consumers a lot of choice. The Ohio Department of Insurance focuses on protecting consumers, while also providing stability and predictability in the market to foster competition and growth," says Robert Denhard with the Ohio Department of Insurance Communications.

Which states have the highest car insurance rates?

Generally, states that are more urban or have large populations tend to have higher average car insurance costs than rural states. More drivers means more accident claims, which spikes costs. But other factors come into play, too, such as car insurance laws.


Michigan is notorious for leading the nation in car insurance costs due to its unique no-fault car insurance laws that provided unlimited benefits. However, auto reform laws that went into effect in July are designed to mitigate these high insurance costs.

Historically, Michigan car insurance laws operated under an unlimited no-fault car insurance mandate that required all drivers to carry Personal Injury Protection (PIP) coverage. PIP helps cover medical expenses for the policyholder, family members and passengers that are injured in a car accident.

While other states that require PIP have put limits on PIP coverage amounts, Michigan did not. Michigan guaranteed unlimited, lifetime medical benefits to auto accident victims, which dramatically increased an insurer’s risk, and your premium. The new car insurance laws allow drivers to choose between PIP limits of $50,000 (if enrolled in medicaid), $250,000, $500,000, or to opt-out if they meet certain eligibility rules.

The reforms also made it so insurance companies cannot rate on a variety of non-driving factors such as: ZIP code, credit score, educational level, home ownership, occupation, marital status or gender. However, even though a ZIP code cannot be used territories can.

Additionally, Michigan ranks second in the country for uninsured drivers. Roughly, 25.5% of drivers in Michigan are without insurance, according to the latest data. This also helps push rates up for insured drivers.

Penny Gusner, senior consumer analyst for CarInsurance.com, offers the following tips for Michigan drivers who want to take advantage of the new auto reform laws:

  • A first step to obtaining cheaper rates inMichiganis to review the coverages and limits you currently have.
  • If you continued with what you had previously, you might have missed out on saving by lowering your PIP limit, which is now allowed.
  • Review if what you have is suitable for your situation. If not, then adjust.
  • Our research shows that lowering PIP limits can lower your rates. However, remember that you must qualify by having a specific type of health care plan for some of the lower limits.
  • Lowering liability limits is not typically a good idea as it is what covers those you may harm and protects your assets.
  • If you have collision, raising your deductible may help you save.
  • The way to save the most is by comparison shopping. Get rates for the policy you want with your current insurer, then comparison shop with at least three other insurance providers to make sure you are getting the best rates.


Louisiana has a different set of issues. Almost 40% of driver are carrying the absolute minimum coverage levels, according to Louisiana Insurance Commissioner Jim Donelon. And, nearly 12% of Louisiana drivers don’t have car insurance. As a result, many drivers to turn to the legal system to get higher insurance settlements.

Louisiana Watchdog reports that Louisiana lawsuit costs are amount the highest in the U.S., with annual expenses nearly hitting $7 billion, 20.6% higher than the national average. Auto accidents are the largest portion of the tort system costs reaching more than$3 billion. These higher payouts lead to higher premiums for everyone as insurers pass their costs on to policyholders.


In Nevada, there is also a high rate of uninsured motorists, 10.4%. And as host to Las Vegas, the iconic gambling and resort destination, it has its share of traffic claims that balance out the more rural areas of the state.

Learn more about how car insurance rates vary by state

There are several reasons why auto insurance rates change by state. One major reason is that the state required minimum car insurance limits you need to have in place to drive legally vary by state. Some are lower than others.

Liability insurance is typically written out showing amounts for each component. These include personal injury liability to pay medical expenses for those you injure in an accident you cause, and property damage liability, which pays for damage you cause to other vehicles and property.

Like this example, for California, 15/30/5:

  • $15,000 for injuries you cause, up to $30,000 per accident
  • $5,000 for property damage

In your particular state, the minimum required liability limits may be as much as 30/60/25, as it is in Texas, or as low as California’s, where it’s 15/30/5.

Also, some states require you to buy personal injury protection and uninsured motorist coverage, in addition to liability insurance.

Why does where you live affect your car insurance rate?

Your insurance company's experience with losses in your neighborhood influences how much you pay. So does your state’s car insurance laws. In addition to state minimum liability requirements that differ, some states, for instance, allow insurers to consider your credit history and gender when calculating your cost, while others don’t allow it.

Additionally, urban areas tend to have more cars on the road more often than rural areas. That leads an increased number of accidents, theft and vandalism. The more claims made in an area, the higher the rates will be.

In your particular ZIP code, factors that can drive rates higher include the number of:

  • Claims for that area and how much they cost
  • Vehicles stolen
  • Fraudulent injury claims
  • Reports of vandalism

Common questions about state-specific car insurance laws

What is a tort state?: Thirty-eight states use the tort system, which means that someone is found at fault for every accident that involves car insurance, even if the fault is determined to be 50/50 between two drivers.

What is a no-fault state?: Under the no-fault system, car insurance companies pay for certain damages (typically bodily injuries) regardless of who was at fault. Laws vary among the 12 states that have no-fault insurance.

No pay, no play states: In states with “no pay, no play” laws, driving without insurance is even more risky than in other states. Uninsured drivers in these states are not compensated for any damage, even in accidents that are not their fault.

Which states share speeding ticket information?: Many states have formal agreements with each other, such as the Drivers License Compact and the Non-Resident Violator Compact, to share information regarding traffic tickets when drivers are ticketed out of state.

Should insurers only base rates on driving record?

A Congressional bill proposed in 2019 would make it illegal for car insurance companies to base rates on anything other than a person’s driving record. In that case, a person’s place of residence would no longer affect car insurance costs.

Eric Poe, lawyer, activist entrepreneur and COO of the not-for-profit CURE Auto Insurance in Princeton, NJ, said the bill “levels the playing field” and protects lower-income consumers against discrimination.

“The purpose of insurance is to pool risks so that everyone who is compelled to buy it can afford it,” Poe said. “

The fundamental mechanism and purpose of insurance is to protect against any one-single catastrophic loss that can't be absorbed by an individual. Ultimately, poor people have no assets to protect and therefore do not receive the typical benefits associated with insurance but are compelled to buy it for statutory reasons (laws require it).

“If you are required to buy insurance by a state government, it is our position that it should be priced fairly. Charging the lowest income drivers (even the safest clean drivers) significantly more than the higher income drivers is simply fundamentally unfair and unjust,” Poe added.

However, Megan Shepherd, insurance editor at finder.com and a licensed insurance agent in health, life, disability and general lines of coverage, said insurers should be able to consider a driver’s state, city and ZIP when figuring out rates.

“For example, a higher population density means a higher probability for accidents and, therefore, more costs that inslourance companies will need to offset. Weather conditions and wildlife also vary by state, since in some states you experience a higher likelihood of damage from say a hurricane or a collision with a deer; those risks factor into your rate,” Shepherd said.

Shepherd said another issue with the legislation is what to do about new drivers, who don’t have a driving record.

In that case, insurers might have to base young driver rates based on statistics alone until they establish a driving record, Shepherd said.
