This guidance document provides clarity to DOT-regulated employers, employees, and service
agents on conducting DOT drug-and-alcohol testing given concerns about the Coronavirus
Disease 2019 (COVID-19). We, as a Nation, are facing an unprecedented public health
emergency that is straining medical resources and altering aspects of American life, including the

DOT is committed to maintaining public safety while providing maximum flexibility to allow
transportation industries to conduct their operations safely and efficiently during this period of
