Commercial Driver's License (CDL)
A commercial driver's license (CDL) is the federally regulated credential required to operate heavy or specialized vehicles, including tractor-trailers, tankers, and many mining and construction trucks. Earning and maintaining a CDL involves classroom instruction, behind-the-wheel training, knowledge and skills testing, medical certification, and ongoing compliance with FMCSA hours-of-service and drug-and-alcohol rules. CDL drivers are a chronic constraint on industrial logistics, and the credential is a high-demand entry point into well-paying supply chain careers.
