Senate Bill No. 40 amends existing laws regarding the transportation and storage of firearms in Oklahoma. It removes liability provisions for property owners, tenants, employers, and business entities that establish or enforce policies prohibiting individuals, except convicted felons, from transporting and storing firearms in locked motor vehicles on their property. The bill allows individuals to file civil actions against those who violate these provisions, with courts mandated to award damages, attorney fees, and enjoin further violations. Additionally, the bill clarifies that the term "motor vehicle" encompasses various types of vehicles required to be registered under state law.

The bill also modifies the Oklahoma Self-Defense Act by ensuring that property owners and business entities cannot prohibit individuals, except convicted felons, from transporting, storing, or carrying firearms in their vehicles while conducting business. It establishes immunity from liability for those who do not restrict such actions, except in cases of gross negligence or willful misconduct. The bill further clarifies that allowing employees to carry or discharge weapons does not fall within their job description or scope of employment. The effective date for these changes is set for November 1, 2025.
