Transportation Secretary Sean Duffy announced Monday that his department is shutting down more than 110 driving schools that issued licenses to drivers who failed required English language proficiency tests.

The action targets schools that bypassed federal standards for commercial driver's licenses. Officials determined the facilities granted credentials despite applicants not meeting English proficiency benchmarks necessary for safe operation of vehicles on public roads.

Federal regulations mandate that commercial drivers demonstrate sufficient English skills to read and understand traffic signs, communicate with law enforcement, and complete required paperwork. The department's review identified widespread noncompliance at the affected schools.

Duffy's decision aligns with ongoing efforts to strengthen oversight of licensing processes. The closures aim to remove unqualified drivers from the roads and restore integrity to the certification system.

States and local authorities will coordinate with federal officials on the transition. Drivers who received licenses through the flagged schools face additional scrutiny and potential retesting.

The move comes amid broader concerns over transportation safety and regulatory compliance across the industry.
