MO HB3192

Law enforcement agencies may only use automatic license plate recognition (ALPR) systems for criminal investigations with reasonable suspicion, missing/endangered person alerts, and stolen vehicle/plate alerts—prohibiting use for general surveillance, immigration enforcement, or monitoring lawful activity

ALPR data must be destroyed within 30 days of collection unless relevant to an ongoing investigation or active missing person alert, with retained data reviewed every 90 days

Beginning January 1, 2027, agencies must record traffic stops initiated from ALPR data and submit annual reports to the Missouri State Highway Patrol on scans conducted, alerts generated, case types, and resulting arrests

Installation of ALPR systems on state highways requires Department of Transportation approval, and agencies may only use systems from an approved vendor list maintained by the Office of Administration

Unauthorized access, personal/commercial use, or improper disclosure of ALPR data is a class A misdemeanor for first offense and class E felony for subsequent offenses
