Minn. Stat. 13.824 subd. 6 requires every agency that operates ALPRs to obtain an independent audit at least every two years, checking that data is properly classified, used only for authorized purposes, destroyed on schedule, and that each query had a documented reason, with results due to state officials within 30 days. The audit is one of the few outside checks on how an agency actually runs its cameras. In practice most Minnesota audits report zero findings, often on a boilerplate template that clears nearly every agency it reviews, so a clean audit usually reflects a light-touch review rather than proof the program meets the intent of the statute. FinePrint's ALPR Audit Watch tracks each agency's audit date, auditor, and findings count.
