California lawmakers are advancing a bill that would permit auto insurers to incorporate driver telematics data into rate calculations, Insurance Journal reported July 9, 2026, marking a potential turning point in how the state's carriers price individual auto policies.
The proposal arrives as California's auto insurance market continues to adjust after years of constrained competition. The California Department of Insurance has been processing a significant backlog of rate filings under the Proposition 103 regulatory framework, which requires prior CDI approval before insurers can change rates. Telematics-based rating, which uses data from smartphone apps or plug-in devices to measure driving behavior, has gained broad adoption across the United States but has faced legislative and regulatory barriers specific to California.
What would the California telematics bill authorize insurers to do?
The proposed legislation would allow California auto insurers to use driving behavior data, gathered through telematics programs, as a factor when pricing individual policies. Under such a framework, metrics including braking patterns, annual mileage, and time-of-day driving could allow carriers to price coverage more precisely to individual risk profiles rather than relying exclusively on broader demographic averages.
Telematics-based programs are already standard practice in many states. Progressive, State Farm, and Allstate each operate usage-based insurance programs that reward lower-risk drivers with premium discounts in states where telematics rating is permitted. California has been a notable exception, partly due to regulatory requirements established under Proposition 103, the 1988 ballot initiative that created the prior-approval rate system now overseen by the California Department of Insurance.
How does Proposition 103 currently govern California auto insurance pricing?
Proposition 103, administered by the California Department of Insurance, requires auto insurers to base rates primarily on three mandatory factors: driving safety record, annual miles driven, and years of driving experience. Telematics programs have long been seen as a tool to measure these factors with greater precision, but the legal pathway for insurers to use telematics-gathered data in rate filings has remained contested under the existing framework.
Under the current rules, any insurer seeking to use telematics-based factors in California would still need to submit those rating plans to the CDI for prior approval before implementation. The proposed bill aims to clarify the legal authority for telematics use without bypassing the CDI's prior-approval review process, according to Insurance Journal reporting on the measure.
What should California drivers know before enrolling in a telematics program?
Participation in telematics programs is typically voluntary. Drivers who enroll share driving data with their insurer through a mobile app or an on-board device, and many carriers operating outside California have reported that drivers who complete telematics measurement periods often qualify for premium reductions reflecting demonstrated low-risk driving behavior.
California already has some of the strongest consumer privacy protections in the country. Earlier in 2026, the California Legislature also examined AB 1833, the Consumer Driving Data Protection Act, a separate measure focused specifically on how insurers must handle and disclose their use of consumer driving data. Any telematics rating framework enacted in California would need to operate within those privacy law requirements, and the California Department of Insurance has noted in prior guidance that new rating factor proposals must align with both Proposition 103 requirements and California consumer protection statutes.
