Should employers include all employees who hold a CDL in their DOT drug and alcohol testing program?

No, only those individuals who drive a CDL CMV for the company should be included in the company�s DOT drug and alcohol testing program. Employees who happen to hold a CDL but are not using the CDL in their jobs are not in a safety-sensitive position and are not subject to Part 382. If, however, the individual is a backup CDL driver who may be called upon occasionally or intermittently to drive a CDL CMV should be included in the company�s DOT drug and alcohol testing program.
