How Does Car Insurance Work in California?
In a Nutshell: California car insurance is unique — the state bans credit scoring, has relatively low minimum requirements (15/30/5), and operates under strict rate-setting rules from Proposition 103. The average full coverage premium is $2,180/year — 12th highest in the nation. Insurers like Geico, State Farm, and AAA dominate the market.
California's Minimum Requirements
| Coverage | Minimum Required | Notes |
|---|---|---|
| Bodily injury (per person) | $15,000 | Lowest minimum in a major state |
| Bodily injury (per accident) | $30,000 | Shared among all injured parties |
| Property damage (per accident) | $5,000 | Dangerously low — won't cover most modern cars |
| Uninsured motorist | Not required (must be offered) | Can reject in writing |
⚠️ California's $5,000 property damage minimum is the second-lowest in the nation. A single fender bender on a modern car can easily cost $8,000–$15,000 to repair.
