In 2012 in the state of Texas, 584,850 citizens were actively licensed to carry a concealed handgun. That amounts to approximately one legally armed citizen out of every 45 people in Texas. As a business owner or manager, if you do not want anyone carrying guns on your commercial premises because you are concerned about the potential violence that could occur, you have two options. First, you can prevent your employees from carrying a handgun by having a written policy prohibiting that in your employee policy manual. However, a recent amendment of the law does allow employees to have their gun locked in their vehicles, even if they are parked in a parking lot on your property.
Second, to prevent the public from carrying a concealed handgun on your property, you must have a “30.06 sign” posted in a conspicuous place clearly visible to the public (at every entrance is the best idea). The sign requirements are a single sign, both in English and Spanish, with 1” high letters, in contrasting colors, containing the exact language from the Texas Penal Code section 30.06. The language in English must read: “Pursuant to Section 30.06, Penal Code (trespass by holder of license to carry a concealed handgun), a person licensed under Subchapter H, Chapter 411, Government Code (concealed handgun law), may not enter this property with a concealed handgun.”
Other signs, such as a picture of a handgun with a red slash through it, are ineffective in Texas and concealed handgun license class instructors tell their students to walk right past those signs. There is a one other valid sign in Texas called the 51% sign, but that only applies to prohibiting the public from carrying handguns on a premises that receives more than half of its income from serving customers alcohol.
It is still illegal for licensees to carry a handgun in Texas at a federal building, at a school, at a public sporting event, in a courthouse, at an election polling place or in a jail or prison, even if those places do not post any kind of sign prohibiting the carrying of a concealed weapon.
