Safety, Dept. of - As enacted, removes present law that requires an offender sentenced to a period of incarceration for a DUI to begin their sentence within 30 days of conviction or, if space is not immediately available in the appropriate municipal or county jail or workhouse within such time, as soon as such space is available; requires, instead, the sentencing court to determine when such an offender is required to commence service of their sentence. - Amends TCA Title 55 and Title 65.

HB 1317 requires Tennessee's Department of Safety to provide a copy of its annual report on ignition interlock devices to the legislative librarian, in addition to legislative committees. The report tracks offenders who have these devices installed on their vehicles and confirms whether each installation followed legal requirements. This change directly affects the Department of Safety (which must submit the report) and the legislative librarian (who will receive it). The bill amends Tennessee Code Sections 55-10-418 and related transportation laws to add this reporting requirement.
