A Connecticut law signed in May tightens ALPR data retention and usage, generally requiring deletion of most data after 21 days unless linked to an active investigation, and restricting ALPR use for immigration enforcement as well as certain healthcare and First Amendment-related investigations.

The law is designed to address privacy concerns by limiting how long data is kept and what it can be used for, reflecting ongoing state oversight of ALPR deployment.

Local decision-making varies across towns and cities, with differences in installation, technology, and data-retention policies, and roughly half of CT police departments reportedly using Flock Safety services.

ALPRs collect license plate numbers along with vehicle make, model, color, location, date, and time, and some systems can identify vehicle characteristics even when plates aren’t visible; alerts and searches can aid investigations, though these systems do not use facial recognition.

Context and regulation summarized through CT Mirror reporting on Reginald David’s coverage and Connecticut legislative actions.

Some communities have paused or reconsidered new ALPR deployments amid privacy and data-sharing concerns, and Governor Lamont has asked municipalities to pause camera deployments pending state guidance.

ALPRs differ from traffic cameras and are not used to enforce traffic laws; they operate continuously rather than being triggered solely by violations.
