What's the minimum car insurance required in California?

The short answer: Since January 1, 2025, California's minimum is 30/60/15 — $30,000 in bodily-injury coverage per person, $60,000 per accident, and $15,000 for property damage. Senate Bill 1107 raised it from the old 15/30/5, the first change since 1967. It's the cheapest legal policy you can buy. It is almost never the one we'd put your family in.

Here's what those three numbers actually buy you. If you cause a crash and injure one person, your policy pays their medical bills up to $30,000. If you injure several people, everyone shares a $60,000 pool. And if you crush someone's bumper — or their brand-new EV — you have $15,000 for their property. That last number is the one that gets Bay Area drivers in trouble first: $15,000 doesn't go far when the car in front of you at the light is a Tesla, a Rivian, or a loaded pickup.

The limits are set in California Vehicle Code §16056 and Insurance Code §11580.1, and SB 1107 already schedules the next step up: on January 1, 2035, the minimum rises again to 50/100/25. If your policy renewed after January 2025, your limits were bumped to 30/60/15 automatically — and your premium likely nudged up with them. That renewal is the moment worth a second look, not a rubber stamp.

At-fault, no-fault — which is California, and why does it matter?

California is an at-fault state. That's not a technicality; it shapes every coverage decision below. In an at-fault (or "tort") system, the driver who causes the crash is legally responsible for the harm, and their insurance pays the victims. There's no separate no-fault bucket that covers your own injuries regardless of blame the way there is in, say, Florida or New York.

What that means in practice: after a crash that isn't your fault, you're relying on the other driver's liability coverage to make you whole. If they carry only the 30/60/15 minimum — or nothing at all — their policy caps out fast, and the rest is a fight or a write-off. That single fact is the argument for two things we'll come back to: carrying higher liability limits so you're not the underinsured driver, and carrying uninsured/underinsured motorist coverage so a broke at-fault driver isn't your problem.

What each coverage actually does

A California auto policy is really a stack of separate coverages. You don't buy "full coverage" off a shelf — you build it. Here's the plain-English version of what each piece does and who it protects.

"Full coverage" is just shorthand for liability + collision + comprehensive, usually with UM/UIM and MedPay layered in. If you have a loan or lease, your lender will require collision and comprehensive until the car is paid off. Once it's yours free and clear, keeping or dropping them becomes a math question about the car's value — one we're happy to run with you.

How much coverage should a California driver actually carry?

The short answer: Carry liability limits that match what you have to lose, not what the state will let you get away with. For most Bay Area households with a home, savings, or steady income, we're usually talking 100/300/100 — not 30/60/15 — plus uninsured-motorist coverage set to match.

Here's the logic. Liability isn't really about your car; it's about your net worth. If you cause a serious injury and the bills run past your limit, the injured party can come after your assets and future wages for the difference. In a region where a typical home carries hundreds of thousands in equity, the state minimum is a thin shield. Raising liability from 30/60/15 to 100/300/100 is often far cheaper than people expect, because you're buying the unlikely-but-catastrophic tail, not the everyday fender-bender.

Then match your uninsured/underinsured motorist limits to your liability limits. It's an odd but important quirk: if you carry 100/300 in liability but only 30/60 in UM/UIM, you've protected everyone else on the road better than you've protected yourself. When one in six drivers around you is uninsured, that gap is the one that bites.

Why is California car insurance priced so differently? (Prop 103)

If you've moved here from another state, your first California renewal probably felt strange — different discounts, different questions, some familiar national perks missing. That's Proposition 103, the 1988 voter law that governs how auto insurance is priced in California, and it works in your favor more than you'd guess.

Under Prop 103, insurers must price your policy primarily on three mandatory factors, in this order: your driving safety record, your annual mileage, and your years of driving experience. Just as important is what they can't use: your credit score, ZIP code, gender, occupation, and education are off-limits as primary rating factors. In most states your credit score quietly moves your premium hundreds of dollars a year. In California it legally can't.

The headline benefit is the Good Driver Discount. Every California insurer must knock at least 20% off the rate you'd otherwise pay if you qualify — and they can't refuse to write you. You're a good driver under the law if you've been licensed at least three years, have no more than one point on your record in the past three years, and haven't been the principal at-fault driver in a crash causing serious injury or death. If you meet that bar and you're not getting the discount, something's wrong with your policy, and it's worth a call.

How do I actually lower my California car insurance?

There's an honest way to save and a dangerous way. The dangerous way is stripping coverage down to the state minimum and hoping nothing happens — that's not saving money, it's borrowing against a bad day. Here's the honest list, roughly in order of impact:

Notice what's not on that list: "shop around every six months" and "chase the cheapest quote." A rock-bottom premium usually means rock-bottom limits, and in an at-fault state that's a trade you feel exactly once. Our job is to find you every discount you're entitled to on coverage that actually holds up — and because we work with more than one market, we can move your policy to the carrier that fits your profile instead of asking you to fit theirs.

The bottom line

California raised the floor, but the floor is still a floor. The 30/60/15 minimum keeps you legal; it doesn't keep you protected in an at-fault state where a single serious crash can eclipse those limits in an afternoon. The smart California policy pairs liability sized to your assets, uninsured-motorist coverage that matches it, and every Prop 103 discount you're owed — starting with the 20% good-driver discount that's yours by law.

If you're not sure whether your current policy does that, bring us your declarations page. We'll read your actual limits, check whether you're getting the discounts you qualify for, and tell you straight whether you're priced right — and whether you're carrying enough. No pressure, and it takes about fifteen minutes.
