California Car Insurance Laws: Minimums, Proof, and Penalties

California car insurance laws require every driver to carry liability coverage of at least 30/60/15, meaning $30,000 for injury or death of one person, $60,000 total per accident for injuries, and $15,000 for property damage. Those limits took effect on January 1, 2025, under Senate Bill 1107, doubling the floor from the 15/30/5 figures that had stood for decades. You can meet the requirement with a traditional policy or an approved alternative, but you must carry proof at all times, and driving without coverage can cost you several times what a basic policy would have.

The Minimum Coverage You Must Carry

Vehicle Code § 16056 sets the floor for any policy issued or renewed on or after January 1, 2025.¹

$30,000 for bodily injury or death of one person in a single accident
$60,000 total for bodily injury or death of two or more people in a single accident
$15,000 for property damage per accident

If your policy still shows the old 15/30/5 figures, it will be updated to the new minimums at your next renewal.²

These are liability limits only. They pay for injuries and damage you cause to someone else. They do not cover your own medical bills, your own vehicle repairs, or situations where someone else hits you and has no insurance of their own. A serious crash can run well past $60,000 in medical costs alone, and you are personally on the hook for anything your policy will not pay.

California Is an At-Fault State

The driver who causes a collision pays for the other party’s medical expenses, lost income, and property damage. In practice, the at-fault driver’s liability insurance covers those costs up to the policy limits, and the injured person can sue for anything beyond that.

This is why the state minimums are a floor rather than a goal. Your liability insurance protects other people from your mistakes; it does nothing for you. Many drivers add uninsured motorist coverage, collision, and medical payments on top of the required liability because the law only forces you to protect others.

Alternatives to a Standard Policy

You do not have to buy a traditional policy. Vehicle Code § 16021 recognizes three other ways to prove financial responsibility.³

A cash deposit with the DMV in the amount set by § 16056. The DMV holds the money as a dedicated fund to settle claims against you, and the required deposit rose with the 2025 limits.⁴
A surety bond from a company licensed by the California Department of Insurance, in an amount tied to the § 16056 minimums.
A certificate of self-insurance, available to any person or organization with more than 25 vehicles registered in their name, issued by the DMV once it confirms the applicant has the resources to cover its own liabilities.⁵

Most individual drivers use a standard policy because the alternatives either tie up a large amount of cash or require qualifying for a bond.

Proof You Must Carry in the Car

Vehicle Code § 16020 requires you to carry evidence of financial responsibility in the vehicle at all times, and you must show it to a peace officer who asks during a stop or an accident investigation.⁶ A phone or other mobile electronic device displaying your insurance information counts. An officer cannot pull you over solely to check whether you have insurance.

You also present proof when you renew your vehicle registration and after any collision.⁷ The DMV runs an electronic verification system that tracks whether your policy is active. If your insurer reports a cancellation or lapse and you do not replace coverage, the DMV will suspend your vehicle’s registration, and you cannot legally drive or even park the vehicle on public roads until you reinstate coverage.⁸

Penalties for Driving Uninsured

Driving without proof of financial responsibility is an infraction under Vehicle Code § 16029, and the ticket price understates the real cost.⁹

First offense: a base fine of $100 to $200, plus penalty assessments that routinely multiply the base fine by four or more, bringing the actual bill above $450 in most cases.
Repeat offense within three years: a base fine of $200 to $500, plus the same assessments, pushing the total into the $900 to $1,200 range or higher.

A court can also order your vehicle impounded. If that happens, you will not get the car back until you show proof of insurance and pay all towing and storage fees.⁹ Add a DMV reinstatement fee if your registration was suspended during the lapse, and a single uninsured stretch can easily cost more than a year of minimum liability premiums.

Accident Reporting and SR-22

You must report a collision to the DMV within 10 days if anyone was injured or killed, or if property damage exceeded $1,000.¹⁰ That rule applies even for minor injuries, and failing to report can lead to a license suspension.

After certain serious violations, including DUI convictions or at-fault accidents while uninsured, the DMV will require you to file an SR-22 certificate. An SR-22 is not a separate kind of insurance. It is a form your insurer files with the DMV to confirm you are carrying at least the minimum coverage. You typically have to maintain the SR-22 for three years from the date your license is reinstated, and any lapse during that period can reset the clock. SR-22 policies cost more than standard ones because they signal high-risk status, and not every insurer offers them.

How Your Premium Is Calculated

California regulates auto insurance pricing more strictly than most states. Proposition 103, passed by voters in 1988, requires insurers to weigh three mandatory rating factors in decreasing order of importance.¹¹

Your driving safety record carries the most weight. At-fault accidents and moving violations push your premium up; a clean record brings it down.
Annual miles driven come next. Drivers with short commutes or limited mileage pay less.
Years of driving experience come third. The longer you have held a license, the lower the risk your insurer assigns you.

Insurers can use additional factors like zip code or vehicle type, but only with approval from the California Department of Insurance, and those secondary factors cannot outweigh the three mandatory ones.¹¹

Credit Scores Cannot Be Used

California prohibits insurers from using your credit score or any credit-based insurance score to set your premium. If you have poor credit but a clean driving record, you will not be penalized for it the way you might be in other states.

The Good Driver Discount

California law guarantees at least a 20 percent discount for drivers who qualify as “good drivers.”¹² To qualify, you must have held a license for at least three years and, during that period, accumulated no more than one violation point, had no at-fault accidents causing bodily injury, and had no DUI convictions within the past ten years.¹³ Every insurer doing business in California must offer the discount, and it applies to the lowest available rate for a comparable driver.

Help Affording Coverage

If you meet income eligibility guidelines and are struggling to afford a standard policy, the California Department of Insurance administers a Low Cost Auto Insurance Program that provides liability coverage satisfying the state’s requirement at reduced rates. Eligibility rules, covered amounts, and enrollment details are available through the Department of Insurance. The program exists specifically to keep lower-income drivers legal and insured rather than forcing a choice between paying for coverage and driving without it.
