California Car Insurance

California drivers must now carry at least 30/60/15 liability coverage under Senate Bill 1107, effective January 1, 2025 and codified in California Insurance Code § 11580.1b¹². This is the first increase to the state minimum since 1967 and is scheduled to rise again to 50/100/25 on January 1, 2035. California's pricing framework is also distinctive: under Proposition 103, the California Department of Insurance must approve rate changes before they take effect, and only three factors (driving safety record, annual mileage, and years of driving experience) are mandatory rating inputs⁴. Credit and gender cannot be used to price personal auto in California⁴⁵. This page owns those California-specific rules; the consumer journey (after an accident, a DUI, a lapse, or a total loss) lives on our situation guides, which each cite California primary sources directly.

Finding cheap California car insurance in practice

Shoppers searching for "cheap car insurance California" and "cheap car insurance quote California" are asking a different question than the carrier-shortlist question. Three structural facts shape the answer here and distinguish California from almost every other state: credit-based insurance scoring is prohibited in personal auto rating under Proposition 103¹; the Good Driver Discount is statutory (California Insurance Code § 1861.025 requires a 20% reduction for drivers meeting the Good Driver criteria), not a competitive differentiator between carriers; and the California Low Cost Auto program (CLCA) provides liability-only coverage to income-eligible good drivers through CAARP-assigned carriers.

1. 1

   Pull the CDI Auto Premium Survey for your profile

   The California Department of Insurance publishes an interactive premium comparison tool at insurance.ca.gov (authorised by California Insurance Code § 12959). Pick your garaging ZIP, driver age, mileage band, and coverage profile. This is a per-scenario comparison, not a published carrier ranking; the CDI explicitly disclaims any endorsement of a particular insurer.

2. 2

   Request three direct carrier quotes with identical inputs

   For full coverage, NerdWallet (updated October 2, 2026) ranks GEICO #1 at $113/mo and Mercury #2 at $115/mo across California; Mercury leads for 30- and 50-year-old profiles and after a DUI or speeding ticket. Pull three quotes at identical limits, deductibles, and mileage band.

3. 3

   Confirm Good Driver eligibility and verify the 20% reduction

   If you meet the Good Driver criteria (three-year clean record, licensed at least three years, no at-fault bodily-injury accidents, no DUI), the 20% reduction is statutory and every CA insurer applies it. Confirm it is visible on the quote.

4. 4

   Check CLCA eligibility if income-qualified

   The California Low Cost Automobile Insurance Program serves income-eligible good drivers (at or below 250% of the federal poverty level, 2024 criteria). Rates vary by county. See the CLCA section below for enrollment.

5. 5

   Compare the final numbers at your ZIP, not at the state average

   California carriers price the same driver profile very differently across ZIP territories. A $400 annual-premium gap between carriers at your ZIP is not uncommon; the state-average published number is not your number.

For the carrier shortlist by shopper profile, see our cheapest car insurance by profile page. Mercury is the carrier most commonly cited as a California budget-value specialist in independent publisher roundups; it is one of several Prop-103-approved carriers that compete heavily on price for standard California profiles. Running three parallel California quotes at identical coverage design is the reliable path to the cheapest personal number.

The 30/60/15 minimum: what changed on January 1, 2025

Senate Bill 1107 (Dodd, 2022) raised the California minimum motor vehicle liability limits under California Insurance Code § 11580.1b from the long-standing 15/30/5 floor to 30/60/15 effective January 1, 2025¹². This was the first increase since 1967. The three numbers refer to:

• $30,000 bodily injury per person. The maximum a policy pays for one injured person's bodily-injury costs when you are at fault.
• $60,000 bodily injury per accident. The maximum a policy pays across all injured people in one accident when you are at fault.
• $15,000 property damage per accident. The maximum a policy pays to repair or replace someone else's property.

These amounts flow only to third parties. They do not pay for your own vehicle after an at-fault accident, your own medical bills, or replacement of your vehicle after theft or another covered event. Personal coverage-limit selection belongs on our coverage-limits guide. The next SB 1107 step, a further increase to 50/100/25, is scheduled for January 1, 2035¹.

Proposition 103: prior approval and mandatory rating factors

California's auto insurance pricing regime was reshaped by Proposition 103, passed by California voters in 1988. Two structural pieces still define how carriers operate today.

• Prior approval. The California Department of Insurance must review and approve rate changes before they take effect⁴. Insurers cannot file and use rates the way they do in Texas and many other states.
• Three mandatory rating factors. Proposition 103 defines the three factors that must carry the most weight in rating: driving safety record, annual mileage, and years of driving experience⁴. Additional optional factors require CDI approval before an insurer can use them.

The practical consequences are that pricing decisions California insurers make are constrained by what CDI has approved, and the mandatory factors carry structural weight above discretionary ones. That is why rating in California often behaves differently from rating in file- and-use states.

Credit-based insurance scoring is prohibited

Credit-based insurance scoring is not a permitted rating factor for personal auto insurance in California under the Proposition 103 rating framework⁴. This is one of the ways California underwriting differs from many other states, and it means that a California quote will not be built on credit history in the way credit-permissive states allow.

Gender is not a permitted rating factor

Under the California Department of Insurance Gender Non-Discrimination in Automobile Insurance Rating Regulation, effective January 1, 2019, gender cannot be used to price private passenger automobile insurance in California⁵. This is a state-specific restriction; many other states allow gender as a rating factor subject to their own DOI rules.

The California Good Driver Discount

The California Insurance Code § 1861.025 Good Driver Discount is a statutory discount, not a marketing program. A qualifying driver receives at least a 20 percent reduction from the insurer's standard rate for a comparable coverage. To qualify, a driver must have three consecutive years of California licensure and no principally-at-fault accident with bodily injury in the qualifying period. Under § 1861.025, absence of prior automobile insurance coverage cannot by itself be a criterion for determining Good Driver eligibility³.

Uninsured / Underinsured Motorist: must be offered

California insurers must offer both Uninsured Motorist (UM) and Underinsured Motorist (UIM) coverage on every personal auto policy. A driver who does not want either must reject the coverage in writing; without a written rejection on file, UM and UIM stay on the policy⁴.

UM applies when the at-fault driver has no liability insurance; UIM applies when the at-fault driver has insurance but not enough to cover the loss. Because a share of California drivers still drive without coverage (even though the state requires liability), UM and UIM are practically important coverage decisions.

Medical Payments coverage: opt-in

California does not require Personal Injury Protection (PIP) on personal auto policies. Medical Payments (MedPay) coverage is offered on an opt-in basis. Many California households coordinate their auto MedPay decision with health insurance and disability coverage they already carry rather than layering PIP-style first-party medical coverage.

DMV insurance verification and financial responsibility

California DMV administers electronic insurance verification for personal vehicles under California Vehicle Code § 4000.37 and the FFVR 18 program⁷. Two mechanics are worth calling out because they matter for daily life with a California registered vehicle:

• Registration proof. Evidence of insurance to register or renew must be from an insurer authorized by the California Department of Insurance. An out-of-state-only policy does not satisfy the requirement⁷.
• Suspension triggers. California DMV can suspend the vehicle registration when insurance information is not submitted within 30 days of a new registration card, when the DMV is notified that the policy was cancelled and a replacement is not submitted within 45 days, or when false proof was used to obtain the registration⁹.
• Affidavit of Non-Use. If a vehicle will not be operated and is not parked on a California roadway, the owner can file an ANU (REG 5090) before cancelling insurance to avoid a registration suspension¹⁰. This is a California-specific mechanic; other states have their own procedures or none.

CLCA: California's low-cost auto program

The California Low Cost Automobile Insurance Program (CLCA) was established by the Legislature in 1999 and is administered by the California Automobile Assigned Risk Plan (CAARP). CLCA is designed to provide income-eligible good drivers with liability protection at affordable rates as a way to satisfy California's mandatory auto insurance law⁶.

CLCA is not an insurer. It is a program that assigns applications to California-licensed insurance companies through CAARP. Policies are sold by licensed producers (agents or brokers) who are CAARP-certified. Households that meet the income and eligibility criteria may find CLCA a materially lower-cost path to satisfying the state liability requirement than voluntary-market pricing⁶. Details, income thresholds, and application information are maintained by CDI at the CLCA program page.
