DOT Drug Testing 

DOT drug and alcohol testing requirements are set by the U.S. Department of Transportation (“DOT”). DOT specifies the requirements for compliance with this set of regulations for employers of safety-sensitive employees in transportation industries including trucking, shipping, aviation, rail, transit, and merchant marines. Companies in these transportation industries are required to give their employees a DOT drug test before hire, to participate in random pools or a drug testing consortium, and to obtain supervisor training to stay in compliance. DOT conducts random and scheduled audits to ensure that companies adhere to these testing guidelines and maintain proper records.
