DEFENSE OF SELF OR OTHERS, MOTOR VEHICLES, AND PUBLIC ASSEMBLIES ON ROADS – Amends and adds to existing law to revise a provision regarding defense of self or others, to provide for operators of a motor vehicle, and to establish provisions regarding public assemblies on roads.

H 679 amends Idaho's self-defense laws to clarify that individuals may use reasonable force (including standing their ground) to protect themselves or others from serious crimes like assault or murder, without needing to retreat. It specifically allows motor vehicle operators to use their vehicle defensively against attackers without criminal liability if they reasonably believe occupants are in imminent danger. The bill also creates new rules for public assemblies on roads, requiring public entities to establish permit policies for road closures while protecting spontaneous gatherings from obstruction. Participants must comply with traffic laws, and violations of permit terms or safety rules may result in misdemeanor penalties.
