In Texas there are three different signs that restrict a License to Carry holder from carrying their handgun into a place of business. They are a 30.06 sign, a 30.07 sign, and a 51% sign.

A 30.06 sign is a sign that a business owner can post to restrict a LTC (License to Carry) holder from entering the business with a concealed handgun. The sign must contain the exact words required by Section 30.06 in both English and Spanish, be placed in an area visible to the public, and have 1" lettering or it will not be considered a legally-binding 30.06 sign. "Gunbuster" signs, or signs with a red slash through a gun, are not considered valid 30.06 postings.

A 30.07 sign is a sign that a business owner can post to restrict a LTC holder from entering the business with a handgun carried openly. The sign must contain the exact words required by Section 30.07 in both English and Spanish, be placed in an area visible to the public and at each entrance to the property, and have 1" lettering or it will not be considered a legally-binding 30.07 sign. "Gunbuster" signs, or signs with a red slash through a gun, are not considered valid 30.07 postings.

A 51% sign is a sign that a business is required by law to post if 51% of their revenue is obtained through on-premises drinking, such as at a bar. Unfortunately this also has the consequence of not allowing LTC holders to enter the premises where the drinking is taking place while carrying their handgun.

Additional places are not required to post a sign to forbid LTC holders from entering the premises with their handgun as Texas law already forbids it, such as court houses and certain educational institutions.
