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

Who is reading your plate?
County by county.

Tennessee law limits how long agencies may keep plate-reader data to 90 days; in 2026 the Knox County Commission ordered the sheriff's fixed cameras removed, the Sullivan County sheriff suspended his program, the Hamilton, Coffee and White county sheriffs and Collegedale ended theirs, and Metro Nashville police have had no plate-reader program since a 2023 pilot ended.

A county’s color reflects any documented agency in it: the sheriff’s office or a city police department. “Not yet checked” is not the same as “none”.

Statewide

  1. 2014 Tennessee law (T.C.A. § 55-10-302, added by Acts 2014, ch. 625) bars government agencies from keeping data captured by automated license plate recognition systems for more than 90 days. Data kept as part of an ongoing investigation may be held longer but must be destroyed when the investigation ends without charges or when the related criminal case concludes. (City of Murfreesboro, Sept. 15, 2023)
  2. 2021 A 2021 state law authorizes TDOT to let law enforcement agencies install cameras on interstate and state highway rights of way. TDOT later said the law gives it permission to allow such cameras but does not require it to. (Tennessee Lookout, May 20, 2022; Tennessee Department of Transportation, April 23, 2025)
  3. April 22, 2021 Gov. Bill Lee signed SB 699 (Public Chapter 201), which made captured plate data from license plate reader systems confidential and not open to public inspection. The Senate passed it 29-0 and the House 86-1. As passed, the confidentiality provision was set to expire July 1, 2026. (Plural Policy (Open States), April 22, 2021)
  4. March 2022 TDOT turned down a West Tennessee police department's request to put a plate reader on a state highway right of way. The department cited an ongoing review of the state's role in plate-reader use. A Tennessee Lookout column reported that the Lee administration was reviewing privacy, data collection and public safety questions around the cameras. (Tennessee Lookout, May 20, 2022)
  5. April 6, 2022 HB 2586, sponsored by Rep. Michael Curcio, would have raised the state's 90-day limit on keeping plate-reader data to 100 days. It was taken off notice in the House Criminal Justice Subcommittee and did not pass. (FastDemocracy, April 6, 2022)
  6. April 23, 2025 TDOT issued Traffic Memorandum TM 2504, which sets out how local governments and law enforcement agencies get permission for surveillance cameras, including plate readers, on interstate and state route rights of way. Each request is reviewed by the Department of Safety and Homeland Security, regional TDOT offices and TDOT's Excess Land Committee, and needs a signed license agreement before installation. Agencies with cameras already on state right of way must go through the same steps. (Tennessee Department of Transportation, April 23, 2025)
  7. July 28, 2026 State Rep. Jason Zachary (R-Knox County) said he plans to talk with other state lawmakers about plate-reader limits before the January legislative session. Rep. Gloria Johnson (D-Knoxville) questioned whether the cameras are needed. U.S. Rep. Tim Burchett has introduced a federal bill that would bar federal funds from paying for license plate readers. (WVLT / WMC Action News 5, July 28, 2026)
  8. Aug. 20, 2026 The Tennessee Sheriffs' Association and the Tennessee Association of Chiefs of Police announced a joint effort to draft recommended principles and model-policy guidance for plate-reader use, which they expect to present to the General Assembly before the 2027 session. Safeguards under consideration include a documented law enforcement purpose for searches, human verification of alerts before enforcement, access limited to trained staff, search audits, rules on sharing, retention and deletion, and discipline for misuse. (Tennessee Association of Chiefs of Police / Tennessee Sheriffs' Association, Aug. 20, 2026)
  9. Aug. 21, 2026 TBI said it supports responsible use of plate-recognition technology, limits access to trained, authorized staff, bars personal and political use, and requires audits. Director David Rausch said the technology must be used responsibly with clear rules and accountability. TBI said it would work with partners and policymakers on standards. (WTVF NewsChannel 5, Aug. 21, 2026; WZTV FOX 17 / WTVC NewsChannel 9, Aug. 23, 2026)
  10. Sept. 2026 In a WVLT interview, Attorney General Jonathan Skrmetti said plate readers are likely legal when they collect data in plain view for a limited purpose. He said he expects the General Assembly to take up the issue, and that lawmakers could choose a ban or set limits on how long data is kept and how it is used. No formal Attorney General opinion was cited. (WSMV / WVLT, Sept. 17, 2026)

No count disclosed. TBI describes using plate-reader data in investigations; it did not say whether it owns cameras.
  1. 2024 TBI said plate-reader data helped investigators quickly narrow in on suspects in the shooting of a Tennessee state trooper. (WZTV FOX 17 / WTVC NewsChannel 9, Aug. 23, 2026)
  2. Aug. 21, 2026 TBI said in a statement that it uses plate-recognition technology in some cases. It said Georgia plate data helped find a 1-year-old taken from Tennessee and helped track a missing at-risk adult to Colorado. TBI said its policy bars personal, political and retaliatory use and requires audits. (WTVF NewsChannel 5, Aug. 21, 2026; WZTV FOX 17 / WTVC NewsChannel 9, Aug. 23, 2026)
Conflicts and open questions

  2. April 23, 2025 Under TDOT's TM 2504, the Department of Safety and Homeland Security reviews every application for a plate reader or surveillance camera on state highway right of way. (Tennessee Department of Transportation, April 23, 2025)

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.
