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
