Sentencing - As introduced, increases the penalty for failing to stop at the scene of an accident when the person knew or should reasonably have known that death resulted from the accident by requiring a mandatory period of confinement of not less than one year and a minimum fine of $10,000. - Amends TCA Title 39; Title 40 and Title 55.

SB 1678 increases penalties for hit-and-run accidents that cause death in Tennessee. The bill requires a mandatory minimum one-year prison sentence and a $10,000 fine for drivers who knew or should have reasonably known death resulted from the accident. It amends Tennessee law to reclassify such offenses as a Class E felony, applying to incidents occurring on or after July 1, 2026. This directly affects drivers who flee the scene of fatal crashes without stopping.
