DOT Drug Testing

The Department of Transportation (DOT) is a U.S. agency where employees are tasked with safety-sensitive responsibilities like operating vehicles or commercial vessels. As such, employees of the DOT are subject to workplace drug and alcohol testing.

Anyone designated by the DOT as a safety-sensitive employee is subject to drug and alcohol testing. This includes careers in:

  • Aviation
  • Commercial Motor Carriers
  • Maritime
  • Pipeline
  • Railroad
  • Transit

The most common drugs Department of Transportation employees are tested for include:  marijuana, cocaine, opiates, phencyclidine (PCP), and amphetamines.
