Car Insurance in California
California is one of the most complex auto insurance markets in the country. With nearly 28 million registered vehicles, congested urban corridors from Los Angeles to San Francisco, and a regulatory environment unlike any other state, drivers face a unique combination of legal rules and market pressures.
In 2025, California raised its mandatory minimum liability limits for the first time since 1967 — a significant shift that affects every driver in the state. At the same time, California's longstanding ban on credit-based insurance scoring, its status as an at-fault state, and its high rate of uninsured motorists all shape what you pay at renewal. This page covers the verified legal requirements, what drives your premium, and how to find your best rate.
California's Minimum Coverage Requirements
Under Senate Bill 1107, California's minimum liability limits increased effective January 1, 2025. The new required minimums are:
| Coverage Type | Minimum Required Limit | What It Covers |
|---|---|---|
| Bodily Injury Liability — per person | $30,000 | Medical costs for one injured person you're at fault for harming |
| Bodily Injury Liability — per accident | $60,000 | Total medical costs for all injured persons in one accident |
| Property Damage Liability — per accident | $15,000 | Damage to another person's vehicle or property |
These limits are commonly expressed as 30/60/15. They replace the old 15/30/5 minimums, which had not been updated in nearly 60 years. The next scheduled increase is set for 2035, when limits will rise to 50/100/25.
Important: Minimum liability coverage protects other people — it does NOT cover your own vehicle or your own medical bills. Collision and comprehensive coverage are optional in California but may be required by your lender or leaseholder if you have a car loan.
Optional coverages California insurers must offer:
- Uninsured/Underinsured Motorist (UM/UIM) — must be offered; requires a signed waiver to reject
- Medical Payments (MedPay) — optional; covers your own medical bills regardless of fault
- Collision and Comprehensive — optional unless required by a lender
California does not require Personal Injury Protection (PIP) and is not a no-fault state. MedPay is the closest equivalent available to CA drivers.
What Drives California Premiums
At-Fault (Tort) System
California is an at-fault state, meaning the driver who causes an accident is legally responsible for the other party's damages. This allows injured parties to sue for pain and suffering, which can increase liability claim payouts and, in turn, insurer costs. PIP is not required because the at-fault driver's liability coverage is the primary payment mechanism.
Credit Scores Are Prohibited
California's Proposition 103 (passed by voters in 1988) prohibits insurers from using credit scores or credit-based insurance scores to set auto insurance rates. California law requires that premiums be based primarily on three factors: your driving safety record, the number of miles you drive annually, and your years of driving experience. This is a significant consumer protection that distinguishes California from most other states, where credit score is a major rating factor.
High Rate of Uninsured Drivers
An estimated 16–17% of California drivers carry no insurance — roughly 1 in 6 vehicles on the road. When an uninsured driver causes an accident, costs are absorbed by other drivers' UM coverage or through litigation. This systemic risk elevates premiums for insured drivers statewide.
Urban Density and Congestion
Los Angeles, San Francisco, San Diego, and Sacramento are among the most congested metro areas in the United States. Higher traffic volume directly correlates with more frequent accidents, theft, and vandalism claims. A driver in rural Northern California will typically pay substantially less than one in the Los Angeles metro for the same coverage.
Wildfire and Weather Risk
California's wildfire exposure has become a significant factor in comprehensive coverage costs, particularly in inland areas and foothill communities. Smoke, falling debris, and evacuation-related accidents contribute to claims. Additionally, flooding and mudslides in Southern California raise comprehensive risk profiles further.
Insurer Market Constraints
California's regulatory environment — including requirements for prior approval of rate changes under Proposition 103 — has caused several major national insurers to pause or restrict new policy issuance in the state in recent years. Reduced competition in some segments can limit consumer choices and affect pricing.
