Amends TCA Title 39.

Tennessee SB1955 amends the definition of "criminally negligent conduct" in the context of criminally negligent homicide to include the failure or refusal to provide aid to an unconscious person or someone in need of medical care, specifically when the individual knows or should reasonably know that the situation arose after the consumption of a controlled substance. This bill affects individuals who may encounter someone in need of assistance under these circumstances. Key provisions include the explicit inclusion of the failure to act in situations involving controlled substances as a basis for criminal negligence.
