Criminal Offenses - As enacted, revises present law concerning driving under the influence. - Amends TCA Title 39 and Title 55.

SB 1400 revises Tennessee's driving under the influence (DUI) laws by two key changes: it permits law enforcement officers to assist medical professionals in obtaining blood samples from drivers using reasonable force during DUI investigations, and it increases the minimum jail sentence for a first-time DUI conviction from one year to one year and six months. These provisions directly affect drivers charged with DUI, law enforcement officers conducting blood tests, and medical personnel involved in the sampling process. The blood sample provision took effect immediately upon the governor's signature on May 5, 2025, while the sentence increase will apply starting January 1, 2026. The bill does not alter DUI testing standards or expand penalties beyond these specific changes.
