AN ACT to amend Tennessee Code Annotated, Title 55, Chapter 10, Part 4, relative to oral-fluid testing.
SB2662 creates a detailed regulatory framework for the use of oral-fluid testing in DUI investigations in Tennessee. The bill defines key terms such as approved devices, accredited laboratories, confirmatory tests, quality-control checks, and articulable facts, and it limits when officers may administer roadside oral-fluid screening. Under the bill, officers may use a screening device only if it is on an approved list, the officer is trained and certified on that device, the device has been properly maintained, and a pre-use QC check is documented. The bill also requires officers to document extensive test information, including device identifiers, lot numbers, calibration status, error codes, and chain-of-custody details, and it requires agencies to retain those records for at least three years or through the end of related proceedings.
The bill further restricts the evidentiary use of oral-fluid screening results. If the state wants to use a screening result as substantive evidence in a criminal case or to support an administrative license action, it must obtain a confirmatory laboratory test from an accredited lab, either from a preserved second oral-fluid sample or a blood sample obtained lawfully in a clinical setting. Without confirmation, the screening result may be used only as a preliminary investigative lead and cannot by itself justify arrest, detention, or license deprivation. The bill also requires preservation of sample material for independent retesting, notice to defendants of preservation and retesting rights, and disclosure of device and testing records in criminal proceedings.
In terms of state law impact, SB2662 would amend Tennessee Code Annotated Title 55, Chapter 10, Part 4, by adding new procedural, evidentiary, and recordkeeping requirements for oral-fluid DUI testing. It authorizes the Department of Safety, in consultation with the POST Commission and the Tennessee Bureau of Investigation, to promulgate rules on training standards, approved devices and kits, documentation, preservation, audits, and reporting. The bill also establishes enforcement consequences for noncompliance, including inadmissibility of improperly obtained screening results and a rebuttable presumption of unreliability for failures involving preservation, disclosure, or related procedures. The act would take effect in stages, with rulemaking and implementation beginning July 1, 2026, and the substantive enforcement provisions applying to actions on or after January 1, 2027.
The overall sentiment suggested by the bill text is cautious and oversight-oriented rather than punitive. The measure appears designed to make oral-fluid testing more scientifically reliable and legally defensible while limiting overreliance on roadside screening alone. Because there are no committee transcripts or recorded votes provided, there is no direct evidence of support or opposition from lawmakers in the available materials.
The main points of contention likely center on the bill’s restrictions on law enforcement discretion and its evidentiary limits. Supporters would likely favor the added safeguards, confirmatory testing, and independent retesting rights as protections against inaccurate results and wrongful license consequences. Critics may view the bill as burdensome for police agencies and prosecutors because it imposes training, documentation, preservation, and laboratory confirmation requirements that could make DUI enforcement slower or more expensive. The bill also draws a clear line that generalized observations alone are insufficient, which may be controversial among those who want broader officer discretion in impairment investigations.
SB2662 would add a new oral-fluid DUI testing section to Tennessee law, creating statewide standards for device approval, officer certification, maintenance, documentation, sample preservation, discovery, and confirmatory laboratory testing. It would limit when oral-fluid screening can be used, make noncompliant results inadmissible or unreliable, and require the Department of Safety to issue implementing rules in consultation with POST and TBI. The bill would directly affect law enforcement agencies, DUI defendants, administrative license proceedings, laboratories, and courts handling impairment cases.
The bill’s tone is generally reform-minded and safeguard-focused, emphasizing reliability, transparency, and due process in DUI enforcement. Because no committee discussion or vote history is provided, there is no recorded legislative debate to indicate a formal consensus or split. Based on the text alone, the measure appears intended to strengthen confidence in oral-fluid testing while constraining its use absent confirmatory evidence.
The likely contention is between evidentiary safeguards and enforcement flexibility. Supporters would likely argue that oral-fluid screening should not be used as a stand-alone basis for arrest, detention, or license penalties without confirmatory testing and proper documentation. Opponents may argue that the bill imposes significant administrative and operational burdens on officers and agencies, especially the requirements for approved devices, certification, QC checks, preservation of samples, and laboratory confirmation before using results substantively. The requirement that generalized officer testimony cannot alone overcome noncompliance may also be a point of dispute.
