Should insurance companies be prohibited from using your marital status to set your auto insurance rates?

The California Department of Insurance has proposed new regulations to bar insurers from considering marital status in auto insurance pricing. This move aims to ensure that rates are determined strictly by driving risk rather than personal circumstances.

Why it matters

The proposal addresses concerns that unmarried drivers currently pay higher premiums than married counterparts for similar coverage. Regulators intend to focus rating criteria on verified safety records and mileage to promote fairness in the insurance market.

Analysis from The Zebra shows single and divorced drivers pay an average of $1,148 for six-month premiums, compared to $1,051 for married motorists. Meanwhile, Bureau of Labor Statistics data indicates auto insurance costs increased 55% from 2020 to 2025.

The players

California Department of Insurance

The details

Insurers currently using marital status, which has been permitted in California since 1996, will be required to revise their rating plans through the state regulatory review process if the measure passes. Under existing mandates from Proposition 103, companies must prioritize driving safety, annual mileage, and years of experience as their primary rating factors.

Marital status was first permitted as an insurance rating factor in 1996.
Auto insurance costs surged 55% between 2020 and 2025.
The Consumer Federation of America tested premiums from five insurers in 2025.
The California Department of Insurance announced the regulatory proposal in September 2026.

Market Dynamics

The proposed rule aligns California insurance regulations with the consumer-protection framework established by Proposition 103. It signals a move toward state-mandated rating standards that emphasize objective driving metrics over demographic indicators.

If enacted, the regulation will likely force insurers to recalibrate their pricing algorithms, which could lead to shifts in premium costs for unmarried California drivers. Policyholders should monitor their future renewal statements to see how these adjustments affect their specific household insurance budgets.

The takeaway

The move reflects a broader trend of states restricting the use of personal lifestyle factors in insurance underwriting. Residents should keep their records updated regarding annual mileage and driving history to ensure they are receiving the most accurate rates available.
