The bill aims to regulate the use of automatic license plate reader (ALPR) systems by state and local governmental entities in Michigan. It establishes definitions for key terms such as "alert data," "automatic license plate reader system," and "captured plate data." The legislation prohibits governmental entities from using ALPR systems except for specific purposes, including identifying uninsured vehicles, locating missing individuals, and supporting ongoing criminal investigations. Additionally, it mandates that captured plate data must not be retained for more than 14 days unless certain conditions are met, such as ongoing investigations or judicial warrants.

Furthermore, the bill requires governmental entities that utilize ALPR systems to adopt and publicly post policies governing their use, including privacy policies that limit data sharing and establish maximum storage durations. Entities must also submit quarterly reports detailing their ALPR practices, including the number of plates scanned, matches with alert data, and any policy violations. The act emphasizes the importance of data security and accountability in the use of ALPR technology, ensuring that captured data is protected from unauthorized access and that the public is informed about the usage of such systems.
