The License-Plate Reader File · MassachusettsIn reporting · updated Oct. 28, 2026

Who is reading your plate?
County by county.

Massachusetts has no state law on police use of license-plate readers: a 2025 House bill to limit them (H.3755) cleared the Joint Committee on Transportation and sits in House Ways and Means, while Cambridge, Methuen, Framingham and more than 20 other cities and towns ended Flock programs in 2025 and 2026 and Lowell, Waltham, New Bedford and Quincy paused theirs.

  1. Jan. 14, 2015 Sen. Cynthia Creem filed S.1817 in the 2015-2016 session to regulate automatic license plate reader systems, including a 14-day deletion requirement and annual reporting; it was referred to the Transportation committee. A similar bill (S.1648) had been filed in 2013-2014. (Massachusetts Legislature, Jan. 14, 2015)
  2. Jan. 14, 2025 Rep. Steven Owens (D-Watertown) filed H.3755, "An Act establishing driver privacy protections," with Rep. Lindsay Sabadosa added on Jan. 21, 2025. The bill would create a new Chapter 90K limiting government ALPR use: 14-day retention unless tied to a specific criminal investigation, a warrant to reach other entities' ALPR data, no sharing except in judicial proceedings, and no use to track constitutionally protected activity. (Legiplex (Massachusetts Legislature bill record), Feb. 27, 2025; NBC Boston / State House News Service, Sept. 9, 2026)
  3. Oct. 7, 2025 The ACLU of Massachusetts published network audits and contract records it obtained through public records requests to nearly 80 police departments, reporting that Massachusetts police spent over $2 million on Flock technology over three years and that out-of-state agencies searched data from Massachusetts departments. An update on Feb. 26, 2026 said more than 80 Massachusetts police departments have Flock contracts. (ACLU of Massachusetts, Data for Justice Project, Oct. 7, 2025)
  4. Jan. 2026 The ACLU of Massachusetts sent a letter to municipal leaders whose police use Flock or another plate-reader vendor, asking them within 30 days to confirm their vendor, obtain settings and contract terms, disable sharing outside Massachusetts, and end contracts where outside sharing cannot be stopped. (ACLU of Massachusetts, Jan. 1, 2026)
  5. March 2026 The Joint Committee on Transportation endorsed H.3755 on an 11-0 vote, after which the bill went to House Ways and Means, where it remained as of September 2026. Its sponsor said he expects to refile a revised version next session. (NBC Boston / State House News Service, Sept. 9, 2026; The New Bedford Light / State House News Service, Sept. 10, 2026)
  6. Sept. 2026 Gov. Maura Healey's office referred questions on plate readers to the Executive Office of Public Safety and Security, whose spokesperson said the office supports appropriate safeguards and will keep monitoring the issue; no executive action was described. A six-member conference committee was working on data privacy legislation (S.2619 / H.5479), which the H.3755 sponsor said may affect ALPR data. (The New Bedford Light / State House News Service, Sept. 10, 2026; NBC Boston / State House News Service, Sept. 9, 2026)
  7. Sept. 2026 The ACLU of Massachusetts said 25 Massachusetts municipalities had canceled Flock contracts or ended pilots over the preceding 18 months. (NBC Boston / State House News Service, Sept. 9, 2026)
  8. Sept. 16, 2026 Rep. Adam Scanlon (D-Bristol) said he plans to file legislation with Rep. Marcus Vaughn setting statewide standards for plate readers, covering data retention, access rules, and auditing. No bill number was given. (Boston 25 News, Sept. 16, 2026)

How this map is built

We start with each county’s sheriff’s office and its largest city police departments, then work outward. Each agency’s entry says whether it comes from agency records or from news reports, and links every source. Companies are tracked separately, so the map can show one company’s customers or all license-plate readers together.
