MSP did not disclose how many freeway readers it installed in its 2023 metro Detroit pilot (WXYZ, Feb. 2023). No current count found.
- Jan. 30, 2023 MSP began installing plate readers along the Southfield Freeway and I-96 in metro Detroit as a pilot it said would later expand statewide; it said images would be kept 30 days and used for serious and violent crimes, not traffic enforcement. (WXYZ, Feb. 2, 2023; FOX 2 Detroit, Feb. 1, 2023)
- March 2023 MSP said readers were in use on freeways in several parts of the state and that it wanted to expand them. (WILX, March 6, 2023)
- June 20, 2023 MSP Procedure Manual 07-13, 'License Plate Reader Systems,' took effect. Under it MSP stores no historical plate data itself (the provider it subscribes to holds the data), MSP's agreements ask providers to keep data from MSP hardware no more than 30 days, every query must cite an incident number, and outside agencies can get data by written request to MSP supervisors with confirmation of an ongoing criminal investigation. (Michigan State Police (PowerDMS public), June 20, 2023)
- July 2026 MDOT said its permits for plate readers on state trunklines require agencies to comply with the MSP license plate reader manual. (Michigan Advance, July 27, 2026)
- Vendor for MSP's own readers not named in any source opened; the manual refers only to the provider MSP subscribes to.
- The newest source on MSP's own readers is from 2023, so current use is marked unconfirmed.
- No Michigan Attorney General opinion or action on plate readers was found.
