Bill No. 1139 amends Section 1280.1 of Title 21 of the Oklahoma Statutes, which governs the possession of firearms on school property. The bill allows for the transport and storage of firearms and weapons on school property under specific circumstances, including participation in approved educational programs or events, and by individuals licensed under the Oklahoma Self-Defense Act. Notably, the bill updates language throughout the section, replacing terms like "gun" with "firearm" and clarifying liability provisions for private schools that adopt policies permitting firearms on their premises.

The bill also specifies that firearms must be properly stored or displayed as required by law and outlines various scenarios under which firearms may be present on school property, such as for veterans participating in approved programs or by school personnel with appropriate licenses. Additionally, it provides immunity from liability for private schools that authorize firearm possession, except in cases of gross negligence or willful misconduct. The act is set to take effect on November 1, 2025.
