This bill aims to enable the United States Virgin Islands and Puerto Rico to issue commercial driver's licenses (CDLs) by amending title 49 of the United States Code. It specifically expands the definition of "State" within commercial motor vehicle safety regulations to include these territories, thereby granting them the authority to participate in the federal CDL program. The legislation mandates that the Federal Motor Carrier Safety Administration (FMCSA) collaborate with the Virgin Islands and Puerto Rico to ensure their full compliance with federal CDL requirements and associated regulations. Furthermore, it establishes a crucial five-year grace period , protecting these territories from the withholding of federal highway funds due to initial non-compliance with CDL issuance standards.
