Criminal Offenses - As introduced, creates a Class A misdemeanor for recklessly storing a firearm in a manner that a person knows or reasonably should know will allow a child younger than 18 years of age to access the firearm and the child brings the firearm to a school. - Amends TCA Title 39, Chapter 17, Part 13.

HB 312 creates a Class A misdemeanor for firearm owners who store guns in a way that allows children under 18 to access them, specifically when a child brings the firearm to school. It directly affects firearm owners in Tennessee who fail to secure guns safely, such as leaving them in unlocked vehicles or unsecured areas where minors could reach them. The law defines "school" broadly to include buildings, buses, campuses, athletic fields, and other properties operated by educational institutions. Violating this law results in a misdemeanor charge, not a felony, with no mention of enhanced penalties for the child or school. The bill takes effect July 1, 2025.
