Conflicts and open questions
  • Retention differs by source: Policy 1015 (2019) says 18 months; the department's 2025 and 2026 reports to legislators say nine months.
  • The Banner (Oct. 1, 2026) reported the department had no readers in 2015.
  • Dated by month: WBFF (Aug. 18, 2026) gives no date for the department's statement.

Statewide

  1. April 14, 2014 The governor signed SB 699 (Chapter 192 of 2014), effective Oct. 1, 2014. It limits police use of captured plate data to a "legitimate law enforcement purpose," shields reader data from the Public Information Act, requires the State Police and agencies using readers to adopt operating and audit procedures, and requires annual reports to the General Assembly starting in 2016. (Maryland General Assembly, April 14, 2014; Maryland Department of Legislative Services, 2015)
  2. March 18, 2015 The House Judiciary Committee gave an unfavorable report to HB 417, which would have barred police from stopping a driver solely because plate-reader data showed the owner held a handgun carry permit. A similar bill, HB 1398, was filed in 2017; the legislature's site shows a March 14 hearing scheduled and no later action. (Maryland General Assembly, March 18, 2015; Maryland Department of Legislative Services, 2015; Maryland General Assembly, 2017)
  3. Oct. 1, 2015 MCAC sent its model audit policy for plate-reader data, developed in August 2015, to all Maryland law enforcement agencies. Under it, agencies audit a random sample of at least 1% of searches (minimum 50). (Maryland State Police / Maryland Coordination and Analysis Center (via Department of Legislative Services Library), March 5, 2025; Maryland Department of State Police / Maryland Coordination and Analysis Center (via Department of Legislative Services Library), March 1, 2026)
  4. May 16, 2024 The governor signed HB 1081 and SB 840 (Chapters 875 and 876 of 2024), effective Oct. 1, 2024. The law covers plate data stored in the cloud, makes captured data the property of the agency that collected it, bars its sale, allows certain data to be uploaded to MCAC, and extends penalties to vendors working for police. The House passed it 119-17 and the Senate 47-0. (Maryland General Assembly, May 16, 2024; Maryland General Assembly, 2024)
  5. Feb. 4, 2025 MCAC's report to legislators for calendar 2024 counted 857 reader units connected to the center and 1,010,086,796 reads retained from 18 agencies. It logged 5,221 requests to the center, 732 of them federal (609 resulting in a release), and reported no breaches. (Maryland State Police / Maryland Coordination and Analysis Center (via Department of Legislative Services Library), March 5, 2025)
  6. Feb. 27, 2026 MCAC's report for calendar 2025 counted 1,077 reader units connected to the center and 1,188,559,099 reads from 19 agencies. It logged 4,737 requests, 674 of them federal (570 resulting in a release), and reported no breaches. MCAC said it could not confirm that the agencies whose reports it forwarded were the only ones in Maryland using plate readers. (Maryland Department of State Police / Maryland Coordination and Analysis Center (via Department of Legislative Services Library), March 1, 2026; The Baltimore Sun (via WBFF FOX45), Aug. 25, 2026)
  7. Aug. 2026 After a Baltimore Sun analysis of the state reports, Sen. Charles Sydnor III (D-Baltimore County) said his office had begun collecting information to decide whether more legislation is needed. In October, The Banner reported that Sydnor, Senate Minority Leader Steven Hershey and Del. N. Scott Phillips want the 2027 session to look at private-sector plate readers, which state law does not regulate. (The Baltimore Sun (via WBFF FOX45), Aug. 25, 2026; The Baltimore Banner, Oct. 1, 2026)

MCAC's table counted 296,536,235 MDTA reads for 2025, the most of any agency. (Maryland State Police / Maryland Coordination and Analysis Center (via Department of Legislative Services Library), March 5, 2025; Maryland Department of State Police / Maryland Coordination and Analysis Center (via Department of Legislative Services Library), March 1, 2026)
  3. Feb. 19, 2026 The MDTA Office of Audits' compliance audit of 2025 plate-reader use (report INT 2026-07) found controls working and no reportable findings. (Maryland Department of State Police / Maryland Coordination and Analysis Center (via Department of Legislative Services Library), March 1, 2026)
Conflicts and open questions
  • The Banner (Oct. 1, 2026) gave 1.5 million reads for 2015, which matches the mobile-unit count in the 2016 state report only.
  • Report figures differ: MDTA's own total and MCAC's table for 2025 are not the same; both are given as filed.
