• Although California is one of the most expensive states to live in, California drivers actually pay less for auto insurance than most other states.

According to NerdWallet’s analysis, the average cost of full coverage insurance in California is $1,659 per year, or about $138 a month, for a 35-year-old driver with a clean driving record. The average cost of a minimum coverage policy in California is $506 per year, or about $42 per month.

California is one of the most consumer-friendly states when it comes to car insurance. Insurers are banned from using a driver’s gender or credit score to price insurance premiums. This means drivers with poor credit won't necessarily pay more for a policy than those with good credit.
