ALPR records in Maryland
Ask your police department or sheriff what their license-plate cameras log, who they share with, and what they cost. A starting point, not legal advice.
Public records law
Maryland Public Information Act

Checked against the official statute text on 2026-10-13. Laws change, so read the source before you rely on it.
Fees & appeals
- Set a fee cap in your letter and ask for an estimate before any work that would exceed it.
- Ask for electronic copies. They're usually cheaper than paper.
- If anything is withheld, ask for the specific exemption and the reasonably segregable parts.
- If you're denied or the deadline passes, ask the agency in writing how to appeal; the appeal route is set out in Maryland's statute (source).

Maryland ALPR law
Public Safety Code § 3-509
Captured plate data can only be used for legitimate law enforcement purposes as defined in the statute including investigating crimes, violations of vehicle laws, terrorist or missing person searches/alerts. Historical license plate data cannot be sold, accessed by vendors without explicit authorization, or uploaded to other agencies/entities outside the state. Law enforcement agencies must adopt procedures for operating ALPR systems and data, including access controls, data protection measures, auditing processes, training and breach of reporting. Data is not subject to disclosure under the Public Information Act. The Department of State Police must submit an annual report with specific details on the use of ALPR systems by law enforcement agencies. An employee of a law enforcement agency or the vendor contracted by the law enforcement agency who violates this subsection is subject to imprisonment not exceeding 1 year or a fine not exceeding $10,000 or both.
