LOS ANGELES, CA – California Insurance Commissioner Ricardo Lara has proposed regulations that would prevent auto insurance companies from using a driver’s marital status as an optional factor when setting private passenger automobile insurance rates.
The proposal, announced Sept. 16 by the California Department of Insurance, would remove a rating factor that insurers have been permitted to use since 1996. The proposed change does not immediately alter premiums, but it could affect how insurers structure rates if the regulations are ultimately approved.
What the proposed rule would change
California’s automobile insurance system operates under Proposition 103, the 1988 voter-approved law that established the state’s framework for insurance rate regulation.
The law requires insurers to consider certain primary factors when establishing automobile insurance rates, including a driver’s driving record, annual mileage and years of driving experience.
Marital status has been permitted as an optional rating factor since 1996. Under Lara’s proposal, insurers would no longer be allowed to use that factor when establishing private passenger automobile insurance rates.
The proposed regulations would therefore change how companies develop their approved rating plans, rather than simply ordering an immediate reduction in premiums for unmarried drivers.
If the rule becomes final, insurers that currently incorporate marital status into their rating plans would have to submit revised plans to the Department of Insurance for review.
Why the issue has drawn attention
Consumer advocates have argued for years that marital status can affect what otherwise similar drivers pay for automobile insurance.
Consumer Watchdog has challenged the practice and has presented insurance quote comparisons involving single, divorced, widowed and married motorists. In one 2025 comparison, the organization examined quotes for a 50-year-old California driver with a clean driving record and found differences associated with marital status among insurers.
The organization’s position is that marital status should not be used to determine automobile insurance premiums because it does not directly describe a driver’s behavior behind the wheel. That is an advocacy position, rather than a finding that every unmarried driver currently pays more than every married driver.
The Department of Insurance’s proposal would address the issue through California’s insurance regulatory process.
Lara points to driving-related factors
Lara said the proposed regulations are intended to move automobile insurance pricing away from marital status and toward factors connected to driving.
“The price of your auto insurance should be based on how you drive, not whether you’re married,” Lara said in announcing the proposal.
The commissioner also pointed to the fact that marital status has remained an optional rating factor for roughly three decades.
The proposed rule would not remove other rating factors from California’s insurance system. A driver’s safety record, mileage and driving experience would remain part of the regulatory framework established under Proposition 103.
The Department of Insurance continues to oversee automobile insurance rate filings and reviews submitted by insurers. Its broader rate-review system operates under Proposition 103 and includes public access to rate-related proceedings and filings.
The proposal follows a 2026 court case
The regulatory move comes after a California appellate court decision involving the commissioner’s authority over optional insurance rating factors.
On July 16, 2026, the California Court of Appeal issued its decision in Ison v. Lara, case No. A170267. The case appears in the court’s official 2026 case listings.
The litigation concerned the authority of the insurance commissioner under Proposition 103 to regulate optional rating factors, including marital status.
The court’s decision did not itself eliminate marital status from automobile insurance rating plans. Instead, the subsequent regulatory proposal represents a separate step by the Department of Insurance.
Consumer Watchdog had participated in the litigation and argued that the use of marital status raised issues under California civil-rights law.
What it could mean for drivers
If the regulation is finalized, California drivers would no longer have marital status incorporated into automobile insurance rating plans that are subject to the new rules.
That does not necessarily mean every single driver will automatically receive a lower premium.
Insurance premiums are based on multiple factors, and insurers could adjust other elements of their rating plans when one factor is removed. The final effect could therefore differ from one insurer to another and from one policyholder to another.
The Department of Insurance would review revised rating plans submitted by companies after the rule takes effect.
For consumers, that distinction is important: the proposal concerns how rates are calculated, not a guaranteed dollar amount that will be removed from every unmarried driver’s bill.
California’s broader insurance regulation
The proposal is part of a broader effort by the Department of Insurance to modify California’s insurance regulatory system.
The department has been pursuing changes to its rate-review procedures, including reforms that took effect in August 2026 to increase transparency and oversight of insurance rate proceedings. Those reforms expanded public access to information about pending administrative hearings and established additional standards for participants in the rate-review process.
The department describes these efforts as part of Commissioner Lara’s Sustainable Insurance Strategy, a broader regulatory initiative addressing insurance affordability, availability and oversight in California.
The marital-status proposal is narrower in scope, focusing specifically on private passenger automobile insurance rates.
What happens next
The proposed regulations must go through California’s formal rulemaking process before they can become final.
That process includes public notice and an opportunity for interested parties to review and comment on the proposed regulatory language.
If the regulations are approved, insurers using marital status in their rating plans would need to submit updated plans and rates to the California Department of Insurance for review.
Until that process is completed, California’s existing rules remain in effect.
For drivers, the proposal therefore represents a potential change to automobile insurance pricing rules rather than an immediate change to their current premiums.
The ultimate effect on individual policyholders will depend on the final regulations, the rating plans submitted by insurers and the Department of Insurance’s review of those plans.
