Car Insurance in California

California Car Insurance: What You Need to Know

California drivers pay an estimated $148 per month ($1,776 per year) for auto insurance, about 1% below the national average of $150 per month [1]. As a tort state with some of the strongest consumer protections in the country, California regulates insurance rates through Proposition 103 and prohibits insurers from using credit scores to price your policy [2].

Coverage Requirements in California

California updated its minimum liability limits on January 1, 2025, through the Protect California Drivers Act (SB 1107) [3]. The new minimums are:

• $30,000 per person for bodily injury or death
• $60,000 per accident for bodily injury or death
• $15,000 per accident for property damage

These replaced the prior 15/30/5 limits that had been in place since 1967. If your policy was at the old minimums, it should have automatically renewed at the new limits [4]. A second increase to 50/100/25 is scheduled for 2035.

California is a tort (at-fault) state, meaning the driver who causes an accident is financially responsible for the other party's injuries and property damage. Liability-only coverage meets the legal minimum, but it does not cover your own vehicle or medical expenses. Optional coverages include collision, comprehensive, uninsured/underinsured motorist, medical payments, towing, and rental reimbursement [4].

What Car Insurance Costs in California

At $148 per month, California sits just below the $150 national average [1]. That is notable for a state with 39 million residents, some of the heaviest traffic in the country, and major metro areas like Los Angeles, San Francisco, and San Diego. Several factors help explain the relatively moderate cost:

• Proposition 103 rate regulation: Approved by voters in 1988, Prop 103 requires every auto insurance rate change to be reviewed and approved by the California Department of Insurance (CDI) before it takes effect [2]
• Credit score ban: California prohibits insurers from using credit scores in auto insurance pricing, unlike most other states where poor credit can more than double your premium
• Mandatory rating factor order: Insurers must weigh your driving record first, followed by annual mileage and years of driving experience [4]

Location still affects your rate within California. Drivers in Los Angeles and San Francisco typically pay more than drivers in rural areas due to higher traffic density, theft rates, and accident frequency. However, because Prop 103 restricts how heavily ZIP code can be weighted, the urban/rural gap is smaller than in most states.

How to Save on Car Insurance in California

California's regulatory framework gives drivers more control over their rates than nearly any other state. Say you are a driver in Los Angeles paying above-average premiums. Here are strategies specific to California that can lower your cost:

• Using the CDI premium comparison tool: The California Department of Insurance publishes a free automobile premium comparison survey covering dozens of carriers by ZIP code [5]
• Qualifying as a good driver: California law requires insurers to give at least a 20% discount to drivers with three or more years of experience and no more than one violation point in the past three years [4]
• Reducing your annual mileage: Because mileage is one of the three mandatory rating factors under Prop 103, driving fewer miles directly lowers your premium
• Comparing quotes from multiple carriers: Even with rate regulation, premiums vary significantly between companies for the same coverage and profile
• Raising your deductible: Choosing a higher deductible on collision and comprehensive coverage reduces your monthly premium

California-Specific Programs and Resources

The California Department of Insurance (CDI) is the primary regulator overseeing auto insurance in the state. CDI handles rate approvals under Prop 103, consumer complaints, and publishes the premium comparison survey [5].

Income-eligible drivers may qualify for the California Low Cost Automobile Insurance Program (CLCA), which provides liability coverage at reduced rates. The program, established in 1999, covers drivers whose vehicles are valued at $25,000 or less. CLCA offers lower liability limits ($10,000/$20,000 bodily injury, $3,000 property damage) at affordable premiums. You can check your eligibility at mylowcostauto.com or by calling 1-866-602-8861 [6].

Drivers who cannot obtain coverage through the standard market due to a poor driving record can apply through the California Automobile Assigned Risk Plan (CAARP) at 1-800-622-0954 [4]. Policies can only be canceled for fraud, nonpayment, or a substantial increase in the insured hazard.

Frequently Asked Questions

What are California's minimum car insurance requirements?

As of January 1, 2025, California requires 30/60/15 liability coverage: $30,000 per person and $60,000 per accident for bodily injury, plus $15,000 for property damage [3]. These limits doubled from the prior 15/30/5 minimums that had been unchanged since 1967. A further increase to 50/100/25 takes effect in 2035.

Why does California ban credit scores in auto insurance?

Proposition 103, approved by voters in 1988, restricts insurers to rating factors directly related to driving risk. The three mandatory factors are driving record, annual mileage, and years of driving experience [2]. Credit scores, which correlate with income and demographics more than driving ability, are prohibited. California is one of only a few states with this restriction.

What happens if I drive without insurance in California?

Driving without insurance in California is illegal. If the DMV does not receive proof of insurance for your vehicle, your registration will be suspended and the vehicle cannot be operated or parked on public roads until coverage is restored [3]. You may also face fines and license penalties if cited by law enforcement.

How can I find the cheapest car insurance in California?

Start with the CDI's free premium comparison tool, which shows rates from dozens of carriers for your specific ZIP code and profile [5]. Qualify for the good driver discount (at least 20% off) by maintaining a clean record for three years. If your income is limited, check your eligibility for the CLCA low-cost program at mylowcostauto.com [6].
