What is the FMCSA Commercial Driver's License Drug and Alcohol Clearinghouse?

To access the Clearinghouse once it is operational, authorized users will be required to request access from FMCSA by registering for the Clearinghouse. Registering this fall is the first step in ensuring you will be ready when the Clearinghouse is operational on January 6, 2020. Learn more about Clearinghouse registration.
