DOT – CDL Drug and Alcohol Clearinghouse


On December 2, 2016, the U.S. Department of Transportation announced a final rule establishing a new “Commercial Driver’s License Drug and Alcohol Clearinghouse.” The clearinghouse database will serve as a central repository for records of violations by CDL holders of the Federal Motor Carrier Safety Administration’s drug and alcohol testing program. Beginning on January 6, 2020, covered employers will be required to register with the clearinghouse, to check the clearinghouse for information regarding current and prospective employees with unresolved violations that prohibit their operation of commercial motor vehicles, and to report drug and alcohol testing program violations (i.e. a positive test for drugs or alcohol, refusal to undergo testing, or undergoing the return-to-duty rehabilitation process).
