The Office of the Secretary (OST) is amending its drug and alcohol testing procedures to authorize employers to disclose to State commercial driver licensing (CDL) authorities the drug and alcohol violations of employees who hold CDLs and operate commercial motor vehicles (CMVs), when a State law requires such reporting.
