TN HB1315

Active duty U.S. Armed Forces members deployed outside Tennessee for more than 30 days may request to toll (pause) their ignition interlock device requirement period by submitting military orders to their provider

Deployments exceeding 90 days allow service members to have the device removed to avoid monthly lease costs, with 30 days after deployment ends to reinstall and resume the requirement

Calibration appointment flexibility expanded to allow completion within 7 calendar days before or after the scheduled date, with the next appointment due within 30 days of actual service (effective January 1, 2026)

Failed breath tests (0.02% BAC or higher) on startup or rolling retests do not count as violations if a retest within 10 minutes shows compliant results and digital images confirm the same person performed both tests

Courts may reinstate driver's licenses for individuals whose only ignition interlock noncompliance involves missed calibration, monitoring, or inspection appointments, provided they meet all other reinstatement requirements
