As I've always understood it, a Peace Officer WHO IS ALSO LICENSED UNDER CHAPTER 411 OF THE GOVERNMENT CODE (License to Carry) is prohibited from disobeying 30.06 and 30.07 signs when off duty. 46.15 exempts us from 46.02 (UCW) and 46.03 (Places Weapons Prohibited) but not 46.035 (Unlawful Carrying of a Handgun by License Holder).
