This bill establishes new regulations regarding critical emergency routes in Oklahoma. It defines "critical emergency route" as roads regularly used by first responders and emergency services. The bill mandates that all roads designated by the Transportation Commission or the Federal Highway Administration as part of the state or National Highway System are automatically classified as critical emergency routes. Additionally, local political subdivisions are empowered to designate other roads as critical emergency routes if they meet the established definition.

The legislation also creates a misdemeanor offense for individuals who willfully obstruct or damage these critical emergency routes, with penalties of up to $500. Furthermore, it prohibits railroads from blocking vehicle traffic at intersections with designated critical emergency routes and requires immediate notification to the Department of Public Safety in case of emergencies that cause such blockages. Violations of this provision can result in fines up to $1,000. The act is set to take effect on July 1, 2025, and includes an emergency clause for immediate implementation upon passage.
