Firearms and Ammunition - As introduced, specifies that a person does not commit an offense if the person possesses or carries a firearm into an area that is posted if, upon the request of an individual authorized to control access to the property, the person immediately leaves the property or stores the firearm in a personal vehicle in accordance with state law. - Amends TCA Title 39, Chapter 17, Part 13.

HB 478 clarifies that a person does not commit a crime if they carry a firearm into an area where firearms are prohibited (e.g., posted private property) and either immediately leaves upon request by the property owner or stores the firearm in their vehicle as required by state law (TCA § 39-17-1313). The bill directly affects individuals carrying firearms on private property where guns are banned, such as businesses or events with posted restrictions. It modifies existing law (TCA Title 39, Chapter 17, Part 13) to explicitly exempt compliant behavior from criminal liability. The change takes effect July 1, 2025, and does not alter existing firearm possession laws or create new restrictions.
