California bill seeks to limit police data retention from license plate readers

California is considering new legislation that could significantly restrict how long law enforcement agencies can store data collected by automated license plate readers (ALPRs). The bill, SB 1013, known as the Automated License Plate Recognition Data Accountability Act, aims to address growing concerns about driver privacy and data security.

The proposed law would redefine ALPR systems and specify which entities are covered by the regulations. It also clarifies the definition of "hot lists" – databases used to flag vehicles, which include records of stolen vehicles, official alerts like Amber Alerts, and lists related to missing persons, major thefts, and violent crimes. The bill seeks to ensure that this powerful surveillance technology is used responsibly.

A key provision of SB 1013 is the establishment of a general 30-day limit for retaining ALPR data. This data could only be kept longer if it is part of an active investigation or criminal proceeding, or if it matches an authorized alert list. Furthermore, by January 1, 2027, public agencies would be required to delete any data exceeding this temporal limit, unless an exception applies.

The legislation also imposes stricter obligations on agencies operating ALPR systems. While the provided text cuts off before detailing these obligations, the bill's intent is to enhance transparency and accountability in the use of this technology, balancing public safety needs with the fundamental right to privacy for California's drivers.
