ALPR records in Massachusetts

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

Massachusetts public records law

M.G.L. c. 66, § 10

Response deadline

Records (or a response) no later than 10 business days after the request is received.

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 Massachusetts's statute (source).

General guidance, not state-specific fee or appeal rules.

What to ask for

  • Search audit logs

    Every ALPR search: date, the officer or agency, the plate or reason entered, and the case number. This shows who is looking, and why.

  • Contract & invoices

    The vendor agreement (Flock Safety or other), renewals, purchase orders and what it costs.

  • Retention policy

    How long plate reads are kept and the records retention schedule that applies.

  • Sharing list

    Every outside agency or organization that can search your local cameras, and the ones your agency can search.

  • Hot lists

    Which watch lists are loaded into the system, who can add plates, on what basis, and how many alerts fired.

  • Policy & camera list

    The written use policy or general order, and the number and locations of cameras.

Re: Public records request: automated license plate reader (ALPR) records

Under the Massachusetts public records law (M.G.L. c. 66, § 10 and related provisions), I request copies of the following records, in electronic format where available:

1. All contracts, purchase orders, renewals, and invoices with any ALPR vendor (including Flock Safety) from January 1, 2024 to present.
2. Any policy, general order, or procedure governing ALPR use, data retention, sharing, and access.
3. A list of outside agencies or organizations with which ALPR data is shared, or which have access to your ALPR system or network.
4. Audit logs, search logs, or audit reports of ALPR queries from January 1, 2024 to present, including the stated reason for each search where recorded.
5. The number and locations of ALPR cameras operated by or on behalf of the agency.
6. Any records retention schedule that applies to ALPR data.
7. Any hot lists, watch lists, or alert lists loaded into the ALPR system (or records describing who may add entries and on what basis), and the number of hot-list alerts from January 1, 2024 to present.

If any portion is withheld, please cite the specific exemption and release all reasonably segregable portions. If fees will exceed $25, please contact me before proceeding. I request a fee waiver because this information is in the public interest and is not sought for commercial purposes.

Thank you,
