Where is car insurance the most expensive in the nation?

The report from Insurify found that California, Missouri, and Minnesota could see rates surge by more than 50% this year. Insurify said that damage from severe storms and weather events such as wildfires could contribute to rising rates in the states, along with state laws about insurance coverage.

Legislative changes in Maryland and South Carolina increase insurers' financial responsibility – such changes could contribute to higher premiums for drivers, according to the report.

From the beginning of 2024 to the end of the year, the national average of car insurance is expected to increase by 22%.

Cassie Sheets, data journalist at Insurify and author of the report, said that three of the 10 most expensive states for car insurance have no-fault systems.

"In these states, drivers file claims with their own insurance companies to receive compensation for their injuries, no matter which party caused the accident. No-fault systems are supposed to speed up claims but have also provided opportunities for insurance fraud," Sheets wrote.

Why are auto insurance premiums rising?

Auto insurance rates are a reflection of the type and amount of coverage needed, personal driving records and where drivers live, USA TODAY reported. Insurers set rates based on operational expenses, including the cost to cover claims.

Repair rates, severity of claims, climate change and an increase in auto thefts, have increased insurers' operational costs.

As repair rates have increased, insurers take on more costs and that correlates as increased premiums for policyholders.
