HB 646 changes Tennessee hunting safety rules by allowing hunters to wear daylight fluorescent pink instead of the traditional daylight fluorescent orange during big game gun hunts (excluding turkey). It removes the legal definition of "daylight fluorescent orange" and requires hunters to wear at least 500 square inches of visible fluorescent color (pink or orange) on the upper body and head. This applies to all hunters participating in big game gun seasons as defined by the Tennessee Wildlife Resources Agency. The law takes effect July 1, 2025, after being enacted as Public Chapter 220 on April 29, 2025.
