Which states have the most expensive car insurance rates?

Michigan, Rhode Island, Nevada, Florida and New Jersey have the highest car insurance rates.

Michigan: Michigan has by far the most expensive car insurance rates in the country. Drivers in Michigan pay an average of $196 a month for minimum coverage. That's more than triple the national average.

After recent changes to Michigan car insurance requirements, drivers now only need $250,000 in PIP insurance, and those with Medicare can opt out altogether. This has helped to lower costs, even though rates are still expensive. Progressive, Auto-Owners and USAA have the best rates for minimum coverage car insurance in Michigan.

Rhode Island: Rhode Island is the second-most expensive state for auto insurance, with rates averaging $100 per month for minimum coverage. That's 72% higher than the national average. Travelers, Amica and Geico typically have the cheapest minimum coverage rates for Rhode Island drivers.

Nevada: With residents paying an average of $97 per month for minimum coverage, Nevada has the third-highest car insurance rates in the country. Traffic congestion is high around cities such as Las Vegas and Reno, which account for much of the state's population. That causes insurance companies to charge rates 67% higher than the national average for all drivers in the state. Nevada drivers can get the most affordable rates from State Farm and Geico.

Florida: Florida is one of the most expensive states for car insurance, averaging $91 per month for a minimum coverage policy. High rates are due to both the large percent of uninsured drivers and the risk of weather damage. Geico and State Farm have the most affordable quotes for drivers looking to save on minimum coverage in Florida.

New Jersey: As a no-fault state, New Jersey car insurance laws require drivers to carry PIP insurance. New Jersey drivers pay about $86 per month for minimum coverage, which is 48% above the national average. Geico has the cheapest liability-only coverage for most New Jersey drivers.

How do state coverage requirements affect car insurance costs?

Each state has different car insurance laws. The car insurance requirements affects car insurance premiums.

States usually require bodily injury and property damage liability insurance, and sometimes uninsured motorist and PIP coverages.

  • Bodily injury liability (BI)
  • Property damage liability (PD)
  • Uninsured or underinsured bodily injury (UIM)
  • Uninsured or underinsured property damage (UIM)
  • Personal injury protection (PIP)

Most states require drivers to have auto insurance. All states except Florida require drivers to have bodily injury liability, and all 50 states and the District of Columbia require property damage liability. About half of all states require uninsured or underinsured coverage, and 16 states require PIP.

Is full coverage required in my state?

Full coverage car insurance is not required by any state. However, it's usually required if you have a car loan or lease.

Full coverage gives you more protection than a minimum coverage policy. It includes collision and comprehensive coverages to pay for nearly any damage to your own car if you cause an accident. Full coverage also has higher liability limits beyond what your state requires.

Full coverage car insurance costs about $90 more per month than a minimum coverage policy. The smallest price difference is in Maine, where full coverage only costs $54 more per month than minimum coverage.

The rule of thumb is that full coverage is worth it if your car's value is more than $5,000, or if it was made in the last decade. Companies that have the cheapest rates for minimum coverage aren't always the cheapest for full coverage.

Of the major national companies, State Farm is the cheapest company for full coverage. But you may find a better deal with a small local or regional company, so get car insurance quotes from multiple companies before purchasing a policy.

No-fault state vs. fault states

Car insurance can be expensive in states where no-fault car insurance is required. This means drivers need to have PIP insurance to cover their own medical bills after an accident, and a driver's right to sue after an accident is limited.

Of the 12 no-fault states, three appear in the top five for the highest auto insurance rates.

The 12 no-fault states

  • Florida
  • Hawaii
  • Kansas
  • Kentucky
  • Massachusetts
  • Michigan
  • Minnesota
  • New Jersey
  • New York
  • North Dakota
  • Pennsylvania
  • Utah

In fault states, the person who causes the car accident must use their liability insurance to pay for the other driver's injuries.

A few states, including New Jersey and Pennsylvania, let drivers pay more to opt out of the no-fault system. This lets them sue for pain and suffering.

Some states, like Delaware, Maine and Oregon, require PIP, even though they are not no-fault states.

What other factors besides location affect auto insurance rates?

In addition to local factors like ZIP code and crime and theft rates, insurance companies also consider personal details when setting insurance rates. This includes your age, driving record and credit score.

  • Driving record. If you've received speeding tickets or been in accidents in the past, companies assume you are a high-risk driver and typically raise your rates.
  • Age. Young drivers pay much more for car insurance. Rates drop quickly between ages 16 to 25. After leveling off in middle age, rates slowly start to rise again after age 60.
  • Credit score. Usually, a good or excellent credit score gets you a lower rate on car insurance. A poor or bad credit score means you'll probably pay more. However, several states, including Michigan, Hawaii and California, have banned the use of credit scores to set rates.
  • Car. The more expensive your car is to repair, the more you'll usually pay for insurance. Expect to pay more if you have a luxury car, sports car or electric car.
  • Marital status. Insurance companies charge married drivers slightly lower rates than single drivers because they see married drivers as less risky.
  • Gender. Men typically spend more time on the road and get into more accidents than women, especially when they're young. Except for a few states, insurance companies generally charge men higher rates than women to reflect this increased risk.
  • Lapse in coverage. Any gap in insurance coverage means your insurance rates will likely be higher. A gap of more than a month could increase your rates by 29%.

Every company has its own unique formula for developing rates, with some companies considering certain factors more than others. That's why it's so important to compare quotes to maximize your chance of getting the best rate.

How moving states can impact your car insurance rates

Moving across state lines will likely impact your auto insurance rates. As a general rule, if the state you're moving to has higher requirements for minimum coverage, you'll pay higher rates. If it has lower requirements, you could pay less for car insurance.

Comparing the requirements can help you start estimating your car insurance to see how your bills might change after a move.

For example, drivers who move from Pennsylvania to Texas will likely pay more for car insurance after the move.

Texas drivers pay 20% more, on average, for minimum coverage than Pennsylvania drivers. This is partly because Texas has higher minimum coverage requirements than Pennsylvania.

The driving conditions of your new state may also affect your rates. For example, minimum coverage car insurance in Pennsylvania costs an average of 53% less than in New Jersey. Both states have identical minimum coverage requirements and are both no-fault states. But New Jersey has more people and more traffic.

You may also need to factor in the cost to change your registration and license with your new state DMV.
