Transportation Secretary Sean Duffy has launched an aggressive federal initiative to eliminate commercially licensed driver (CDL) training schools that fail to meet safety and quality standards. The Trump Administration's USDOT has announced shutdowns of thousands of CDL training schools deemed to be 'CDL mills' — facilities that prioritize profit over proper driver training and highway safety. The enforcement action represents a major escalation in the government's efforts to address the proliferation of inadequate CDL training programs. In 2025, the USDOT reported shutting down 7,500 CDL training schools that failed to meet the Trump Administration's readiness standards. Further intensifying the campaign, the Federal Motor Carrier Safety Administration (FMCSA) conducted approximately 1,400 'sting operations' across multiple states in a coordinated five-day enforcement effort designed to root out noncompliant CDL mills. Over 550 CDL schools have been ordered to shut down as a result of these operations. The initiative aims to protect public safety by ensuring that commercial drivers receive adequate training before being licensed to operate large vehicles on public roads. CDL mills have long been criticized for rushing drivers through training without ensuring they have mastered essential safety skills, contributing to increased accident rates and highway safety concerns. Duffy has declared that the transportation sector must maintain rigorous standards for driver licensing and training. The administration has made it clear that any training facility unwilling to meet federal readiness requirements will face enforcement action.
