The bill enacts Part B of Chapter 51 of Title 51 of the Louisiana Revised Statutes, titled the "Louisiana Critical Infrastructure Protection Act of 2026." This legislation aims to safeguard the state's critical infrastructure from foreign adversaries by prohibiting their access and assessing vulnerabilities related to sanctioned communications equipment. It specifically bans the use of adversary cameras and laser sensor technologies in Louisiana's transportation systems. The bill also outlines definitions related to critical infrastructure, foreign adversaries, and operational command authority, and establishes rules for construction that align with federal law.

Additionally, the bill prohibits companies from entering agreements that would allow foreign adversaries to exercise operational command over critical infrastructure. It allows for exceptions under certain conditions, such as when no reasonable alternatives exist. The legislation mandates the removal of prohibited software from critical infrastructure and ensures that telecommunications and electric utilities in compliance with federal law are exempt from these provisions. The Attorney General is granted the authority to enforce these regulations through civil proceedings. The provisions of the bill will take effect on different dates, with enforcement provisions starting on November 29, 2026.
