To modify a certain commercial zone in Texas to include Zapata County, and for other purposes.

HR 6240 adds Zapata County to an existing commercial transportation zone in Texas that includes Cameron, Hidalgo, Starr, and Willacy Counties. This change affects commercial motor vehicle operators and safety regulations for traffic moving within this expanded zone. The bill requires Texas to submit a traffic monitoring and safety enforcement plan to the Transportation Secretary within three months of enactment, with the zone modification taking effect six months after the bill becomes law. The change specifically applies to transportation of property under federal law (49 U.S.C. § 13506(b)).
