MI HB5493

Restricts Michigan governmental entities from using automatic license plate reader (ALPR) systems except for specific purposes: identifying uninsured/unregistered vehicles, locating vehicles tied to outstanding arrest warrants or missing persons, finding stolen vehicles, investigating crimes, parking enforcement, toll collection, and controlling access to secured areas.

Requires captured plate data to be deleted within 14 days unless retained as evidence, subject to a preservation request, court disclosure order, judicial warrant, or part of an active criminal investigation.

Mandates governmental entities using ALPR systems adopt and publicly post usage and privacy policies on their websites, including automatic data deletion protocols.

Requires quarterly public reports detailing the number of plates scanned, alert matches, arrests resulting from matches, preservation requests, disclosure orders sought and denied, data sharing with external agencies, and policy violations.

Establishes that law enforcement may manually enter license plates into ALPR systems only when relevant to ongoing criminal or missing persons investigations, with documented justification required.
