Mexico's National Guard gains power to arrest, fine drivers on federal highways

The Mexican National Guard has gained new responsibilities, now empowered to enforce traffic laws on federal highways and bridges. A reform to the Federal Highway and Bridge Traffic Regulations, published in the Official Gazette of the Federation on May 25, 2026, officially grants this authority to the National Guard.

This change means the federal corporation will directly participate in managing and monitoring traffic operations on federal roads. The decree stipulates that indications from National Guard members will take precedence when they are performing traffic control and surveillance duties on these routes.

It is important to note that this reform applies exclusively to federal jurisdiction roads and bridges. The National Guard will not assume traffic functions on municipal streets or state avenues, though future changes are not ruled out. The publication confirms modifications to the existing regulations and outlines the National Guard's new powers for enforcement.
