DUI Offenses - As introduced, adds a 30-day mandatory minimum period of incarceration for persons convicted of driving under the influence if, at the time of the offense, the person was within a marked school zone and a warning flasher or flashers were in operation. - Amends TCA Title 39; Title 40 and Title 55, Chapter 10.

HB 1755 adds a mandatory 30-day jail sentence for drivers convicted of DUI who were operating a vehicle within a marked school zone when warning flashers (like those on school buses) were active. This applies to all DUI convictions meeting both conditions, increasing the sentence beyond the standard penalty under Tennessee law. The bill amends Tennessee Code Sections 55-10-401 and 55-10-402 to implement this change, effective July 1, 2026. It directly affects drivers convicted of DUI in active school zone scenarios with operational warning lights. The provision does not apply to DUI offenses without these specific conditions.
