A very literal interpretation of what you state appears to be true. However, I suspect the intent in 30.05 for a defense to prosecution was for carry under authority of a CHL, even though not explicitly stated, and a 30.05 trespass arrest may be a possibility for the sign the OP posted. I would stay off the property with a firearm. I think there is high probability you are at risk for arrest for a 30.05 or a 30.06 violation.ScottDLS wrote:
The 30.06 doesn't apply to a CHL because definition of "premises" does not include parking lots. <----Edit. I was wrong. It's because if you keep gun in your car and have a CHL, PC 30.06 doesn't apply because you're carrying under MPA, not "authority of CHL". And 30.05 DEFENSE still applies becaue you HAVE a CHL.
From PC30.05:
(f) It is a defense to prosecution under this section that:
(1) the basis on which entry on the property or land or in the building was forbidden is that entry with a handgun was forbidden; and
(2) the person was carrying a concealed handgun and a license issued under Subchapter H, Chapter 411, Government Code, to carry a concealed handgun.
