The San Diego City Council has voted to continue the Automated License Plate Reader (ALPR) program, allowing the police department to maintain and expand its use of this technology. While the ALPR has proven effective in combating crime, concerns regarding privacy and data sharing practices have emerged.

The ongoing program reflects the city’s commitment to balancing public safety with privacy rights.

San Diego City Council Votes to Continue Automated License Plate Reader Program

San Diego, CA – On December 9, 2025, the San Diego City Council voted to continue the use of Automated License Plate Reader (ALPR) technology, a decision that has sparked ongoing debate over privacy and data sharing practices.

Council Decision

The council’s vote ensures the San Diego Police Department (SDPD) can maintain and expand its ALPR system, which has been operational since December 2023. This technology utilizes cameras to capture and analyze vehicle license plates, aiding in crime prevention and investigation efforts.

Effectiveness of ALPR Technology

Since its deployment, the ALPR system has been credited with significant contributions to public safety. The SDPD reports that the technology has assisted in over 600 investigations, leading to the recovery of more than $6 million in stolen property and resulting in approximately 420 arrests. Notably, vehicle thefts in San Diego decreased by 20% between 2023 and 2024, a trend attributed to the effectiveness of ALPR technology.

Privacy Concerns and Community Response

Despite these successes, the program has faced criticism from privacy advocates and community groups. Concerns center around potential misuse of data, unauthorized access, and the sharing of information with federal agencies, including Immigration and Customs Enforcement (ICE). In response to these issues, the SDPD has implemented measures to restrict data sharing, ensuring that ALPR data is not shared with federal immigration agencies and is only accessible to trained users within the department. Additionally, the data retention period has been limited to 30 days, aligning with local regulations.

Background Context

The use of ALPR technology in San Diego was initially approved in 2023 under the Transparent and Responsible Use of Surveillance Technology Ordinance. This ordinance requires annual reviews of surveillance technologies to assess their impact on privacy and civil liberties. The recent council vote marks the first such review since the program’s inception, reflecting the city’s commitment to balancing public safety with individual privacy rights.

Looking Ahead

As the ALPR program continues, the San Diego City Council has emphasized the importance of transparency and accountability. Ongoing evaluations and community engagement are expected to address concerns and ensure that the technology serves the best interests of the public while safeguarding privacy rights.
