ALPR law in Maine
Maine regulates automated license plate readers under 29-A M.R.S. § 2117-A. The statute caps retention at 21 days. Maine bans ALPR use outright and then carves out three permitted users: the Department of Transportation, the State Police for commercial vehicle screening, and law enforcement agencies. Plate data that is not investigative or commercial-screening record information may not be kept beyond 21 days, and violating the section is a Class E crime.
