The bill amends Section 37.125, Education Code, so a person commits an offense if, in a manner intended to cause alarm or personal injury to another person or to damage school property, the person intentionally exhibits or uses a firearm in or on any school property. School property includes parking lots, parking garage, or other parking area that is owned by a private or public school or a school bus being used to transport children to or from school-sponsored activities of a private or public school.

A person also commits an offense if they threaten to exhibit or use a firearm in or on property or were in possession of or had immediate access to the firearm; or threatens to exhibit or use a firearm in or on a bus, as described above. Exhibition or use of a firearm can result in being charged with a Class A misdemeanor or a third degree felony.
