MS HB528

Prohibits counties and municipalities from using automated recording equipment or automated license plate recognition systems to enforce traffic laws, speed limits, or vehicle liability requirements, effective July 1, 2025.

Requires all existing automated recording equipment or systems to be removed by July 1, 2025.

Permits mobile automated license plate recognition systems mounted on law enforcement vehicles that are wholly owned and operated by local law enforcement agencies, subject to written policy requirements covering data use, retention, sharing, training, oversight, and security.

Establishes that positive matches from automated license plate recognition systems alone cannot constitute reasonable suspicion for vehicle stops; officers must develop independent reasonable suspicion or visually confirm the license plate matches specific criteria (stolen vehicles, wanted persons, outstanding warrants, commercial trucking violations, criminal investigations, major crimes).

Requires law enforcement agencies using automated license plate recognition systems to audit their use annually and update system databases every 24 hours or as soon as practicable after updates become available.
