Drivers in California pay an average of $93 per month for liability coverage and $191 for full-coverage insurance, according to our data. In comparison, the national averages are $98 for liability coverage and  $182 for full coverage.

California’s rate increases are due to a variety of factors, including:

• Vehicle parts and auto repair costs: California has some of the nation’s highest auto repair bills.^[2] The cost of vehicle parts continues to rise due to supply chain issues and tariffs.^[3] Growing claims expenses push insurers to raise auto insurance premiums to recoup revenue losses.^[4]

• Thefts and vandalism: California leads the country in catalytic converter thefts and vehicle theft rates, according to the National Insurance Crime Bureau.^{[5] [6]} For example, Mercury Insurance saw a 40% rise in the number of comprehensive claims for auto theft and vandalism in California in 2021.

• State regulations: As of Jan. 1, 2025, Senate Bill 1107 requires California drivers to have higher liability limits. Though the legislation aims to protect Californians in a crash, higher minimum-coverage requirements drive up insurance rates.^[7]

How to Save Money on Your Car Insurance in California

Although California car insurance may be expensive, you still have ways to save money on your premium. Some tips to lower the cost of auto insurance in California include:

• Shop around regularly. Many factors go into insurance pricing, and every company has its own way of calculating rates. Comparing car insurance quotes when your current policy renews or when you make a change can ensure you’re always getting the best deal.

• Raise your deductible. If you can’t afford to fix or replace your car, it’s usually worth having comprehensive and collision coverage. Increasing your deductible lowers your premium, but you’ll take on more financial responsibility when you file claims.

• Bundle your policies. The multi-policy discount usually provides the largest car insurance discount, and you can get it by bundling your home and auto insurance with the same company.

• Consider telematics. If you’re a safe driver, allowing your insurer to track your driving habits could lead to significant savings.
