Dozens of commercial vehicle drivers failed to prove that they can speak and read English during interviews with the Wyoming Highway Patrol last month.

The Wyoming Highway Patrol – Commercial Carrier Division recently shared the top commercial vehicle violations uncovered during June 2025.

The violation that topped the list is “Operating a CMV without proof of periodic inspection,” but not far behind at #5 on WHP’s top ten violation list is “Driver cannot satisfy English language proficiency (ELP), failed interview,” with 66 violations issued in June.

Non-compliance with existing federal regulations requiring ELP for commercial vehicle drivers was declared an out-of-service violation as of June 25, 2025, following a major push from the White House for increased enforcement of language requirements for truckers.

In order to avoid being placed out-of-service, commercial vehicle drivers must demonstrate the ability to read and speak the English language sufficiently to converse with the general public, to understand highway traffic signs and signals in the English language, to respond to official inquiries, and to make entries on reports and records, officials say.

WHP reported conducting a total of 1,346 commercial vehicle inspections in June 2025, and troopers thanked the truckers who passed through their inspections without violations:

“Well over one third of drivers inspected had clean inspections, including 214 trucks who earned a new CVSA decal on the windshield. A big thank you to all the drivers who keep their logs up to standard and their trucks in great shape. You are doing your part in keeping the highways safe.“

English language proficiency also cracked WHP’s top ten CMV violations in May 2025, with 71 violations.
