HB 1315 modifies Tennessee's ignition interlock device laws to provide flexibility for drivers. It allows people with ignition interlock requirements to attend device calibration, monitoring, or inspection at any time within a 14-day window (7 days before or after their scheduled appointment) without penalty. The bill also creates a new provision for active-duty military members deployed outside Tennessee for over 30 days, enabling them to temporarily pause their ignition interlock period by submitting military orders. Courts can reinstate driver licenses if the only noncompliance was with device appointments and the driver has no other license restrictions. These changes apply to all drivers required to use ignition interlock devices under Tennessee law.
