DOT Drug Testing Services LLC was founded to keep nearly 8 million people who perform safety sensitive transportation jobs safe. As part of a Consortium/Third-Party Administrators (C/TPAs) that manage all, or part, of our customers’ DOT drug and alcohol testing program, including maintaining required testing records, and providing on-going reporting.



We perform tasks as agreed to with our customers to assist in implementing the drug and alcohol, testing program and to help keep them compliant with the DOT/FMCSA Drug and Alcohol Testing rules and regulations. We manage the DOT random testing programs of several customers, including those of owner-operators who are not permitted to manage random testing themselves.


As we manage owner-operator programs we play a very unique service agent role. While §40.355(k) prohibits us from serving as "designated employer representatives" (DER), we are authorized to perform a number of customer functions in cases of owner-operators, and single driver employers.
