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 courses or events, and by individuals licensed under the Oklahoma Self-Defense Act. Notably, the bill updates language throughout the section, replacing terms such as "gun" with "firearm" and clarifying liability provisions for private schools that adopt policies permitting firearms on their premises.

The bill also specifies that governing entities of private schools will be immune from liability for injuries arising from the adoption of such policies, except in cases of gross negligence or willful misconduct. Additionally, it outlines various scenarios under which firearms may be possessed on school property, including by peace officers, military personnel, and designated school staff, provided that appropriate policies are in place. The act is set to take effect on November 1, 2025.
