The short version: California's rule is that every driver and every owner of a motor vehicle must at all times be able to establish financial responsibility, and must carry evidence of it in the vehicle (Vehicle Code section 16020). A liability insurance policy is how almost everyone does that, but it is not the only way. This guide covers the law itself — who it applies to, the ways to meet it, the proof, and what happens when you do not. For what the 30/60/15 numbers pay, see what the 30/60/15 limits mean; for whether the minimum is enough for you, see California minimum coverage.
Who the law applies to
Both drivers and owners. The duty sits with every driver of a motor vehicle and every owner of one, "at all times" (section 16020). That is why the DMV tracks insurance on registered cars and not only on drivers, and why borrowing a car does not move the duty off you.
The four ways to meet it
The DMV accepts any of these:
- A liability insurance policy — what almost every driver uses. To count, it must generally come from a company admitted to do business in California (Vehicle Code section 16056).
- A $75,000 cash deposit with the DMV.
- A $75,000 surety bond.
- A DMV-issued certificate of self-insurance.
Sources: the DMV's insurance requirements page lists the four forms and the amounts, and Vehicle Code section 16021 sets out the forms that establish financial responsibility after an accident (it also covers public entities and charitable risk pools).
The minimum limits — and the change already scheduled for 2035
A policy counts only if it carries at least $30,000 for injury or death of one person, $60,000 for injury or death of two or more people in one accident, and $15,000 for damage to others' property, for any policy issued or renewed on or after January 1, 2025 (Vehicle Code section 16056; the same figures define "proof of financial responsibility" in section 16430).
The law already schedules the next step: for policies issued or renewed on or after January 1, 2035, each minimum rises by $20,000, $40,000 and $10,000 — which makes it 50/100/25 (sections 16056 and 16430).
The proof you must carry
"Evidence of financial responsibility" in the car can be (section 16020):
- the insurer's ID card or other form the DMV specifies;
- an insurance binder or covering note — which is why a policy bound today is proof today;
- for a self-insurer or depositor, the DMV's certificate or deposit letter;
- for a government-owned vehicle, a showing that it is publicly owned.
You may show it on a phone, and an officer may look only at that evidence on the device (Vehicle Code section 16028).
When the state checks
| Moment | What the law says |
|---|---|
| A traffic stop | When you are cited for another violation, the officer requests and verifies your evidence; if you cannot provide it, you can be cited for that too. An officer may not stop you solely to check for insurance (section 16028). |
| An accident | If an officer or collision investigator is called to a reportable accident, every driver involved must provide evidence (section 16028). Separately, the driver must report the accident to the DMV within 10 days on the SR-1 form when it caused over $1,000 in property damage to any one person, or any injury or death (section 16000). |
| Registration | Insurers report to the DMV electronically. For a new registration or a transfer, evidence must reach the DMV within 30 days of the registration certificate being issued; after an insurer reports a cancellation, the DMV must give the owner at least 45 days' notice before suspending the registration (section 4000.38). |
What the minimum does not do
- It does not pay for your car. Liability pays other people. Collision and comprehensive are optional under the law — a lender usually requires them on a financed car.
- It does not pay for your injuries — but uninsured motorist coverage, which does when an uninsured driver is at fault, must be included in a California liability policy unless you and the insurer delete it by written agreement (Insurance Code section 11580.2).
- It does not cap what you owe. The limits cap what the insurer pays; anything beyond them is a claim against you.
What happens if you are not covered
- A citation: a fine of $100 to $200 plus penalty assessments on a first offense, $200 to $500 plus assessments after that, and the court may order the vehicle impounded (Vehicle Code section 16029). If you were insured but could not show it, written evidence filed with the court gets the charge dismissed (section 16028).
- A suspended registration after the insurer reports a cancellation and the notice period passes (section 4000.38).
- A suspended license after an accident: if you were uninsured in a reportable accident, the DMV must suspend your driving privilege, for at least a year and until you file proof, which you then keep on file for three years (sections 16070 and 16072). Our guide to driving without insurance walks through that path.
