3.1 California Auto Insurance Requirements

Proof of Financial Responsibility

California requires every owner or operator of a registered vehicle to maintain financial responsibility for damage they cause. The overwhelming majority satisfy this by purchasing an auto liability policy, but California Vehicle Code 16020-16021 also recognizes three other methods: a $35,000 cash deposit with the DMV, a DMV-issued surety bond for $35,000, or a self-insurance certificate for fleets of 25 or more vehicles. Drivers must carry evidence of coverage and present it on demand, and law enforcement and courts now accept electronic proof displayed on a phone.

California is a tort (at-fault) state. The driver who negligently causes a crash—and that driver's liability insurer—pays for the injuries and property damage suffered by others. This is the opposite of a no-fault state, where each party first turns to their own coverage regardless of blame.

SB 1107 and the New 30/60/15 Minimums

The single most important recent change: the Protect California Drivers Act (Senate Bill 1107) took effect January 1, 2025 and raised the statutory minimums that had stood since 1967. Producers must memorize both the new and old figures because exam items contrast them.

The new limits are codified in Insurance Code 11580.1b and Vehicle Code 16056. Because the increase applies at the policy's next renewal, not instantly on January 1, 2025, a policy issued in late 2024 carries old limits until it renews. SB 1107 also schedules a second increase to 50/100/25 on January 1, 2035.

Uninsured and Underinsured Motorist Coverage

Under Insurance Code 11580.2, an insurer must offer uninsured motorist (UM) and underinsured motorist (UIM) coverage with every bodily-injury liability policy. The offer is mandatory; the purchase is not. An insured may reject UM/UIM in writing, and that signed waiver carries forward to renewals until revoked. If the insurer never makes a valid offer, the law imputes UM coverage equal to the liability limits.

• UM pays when the at-fault driver has no insurance or is a hit-and-run.
• UIM pays the gap when the at-fault driver's limits are lower than the victim's damages.
• Insurers need not offer UM limits above 30/60, even on higher liability policies.
• California generally prohibits inter-policy stacking of UM/UIM across separate policies (Section 11580.2(k)).

Low Cost Automobile (CLCA) Program

The California Low Cost Automobile (CLCA) program, administered by the Department of Insurance, gives income-eligible drivers an affordable path to legal coverage. To qualify a driver must be at least 19, hold a valid California license, have household income at or below 250% of the federal poverty level, drive a vehicle valued at $25,000 or less, and have a clean record (no more than one at-fault property-damage accident or one point in three years). CLCA provides reduced liability limits of $10,000/$20,000 bodily injury and $3,000 property damage, with optional UM and medical-payments add-ons.

Proposition 103 Rating Factors and the Good Driver Discount

Proposition 103 (1988) controls how auto rates are set. It requires that the three mandatory rating factors be weighted in decreasing order of importance: (1) the insured's driving record, (2) annual miles driven, and (3) years of driving experience. Optional factors (such as territory) may be used only if they have less weight than the three mandatory ones, and the use of credit history to price personal auto insurance is prohibited.

Prop 103 also created the Good Driver Discount. A driver qualifies with three years of driving experience, no more than one violation point in the prior three years, and no at-fault accident causing death or damage over $500. Qualified drivers must be charged at least 20% below the otherwise-applicable rate, and every insurer writing auto in California must offer a Good Driver policy.

Penalties and Coverage Components

Driving without the required financial responsibility carries real consequences. A first offense brings a fine of $100 to $200 plus penalty assessments (raising the total to several hundred dollars), and the DMV may suspend the vehicle's registration. If an uninsured driver is in an at-fault crash, the DMV can suspend the driver's license for up to four years, reinstating after one year only if the driver files an SR-22 financial-responsibility certificate. 4), an uninsured driver injured by another motorist generally cannot recover non-economic damages such as pain and suffering.

A standard California personal auto policy combines several coverage parts the producer must distinguish:

• Bodily injury and property damage liability — the only legally mandated coverages.
• Medical payments (MedPay) — optional, pays the insured's own medical bills regardless of fault.
• Collision and comprehensive (other-than-collision) — optional first-party physical-damage coverages, typically required by lenders.
• Uninsured/underinsured motorist — must be offered but may be rejected in writing.

Liability is mandatory; the rest are optional but commonly purchased to protect the insured's own vehicle and finances. Producers should also know that California does not require personal-injury-protection (PIP) or no-fault medical coverage, because the state operates on a tort liability system rather than a no-fault one, which is a common point of confusion for candidates moving from other states.
