What is the Clearinghouse?

The FMCSA Clearinghouse is a repository database where DOT drug and alcohol violations are recorded. Violations include but are not limited to positive drug and/or alcohol test results, refusals to test and actual knowledge of a illicit drug or alcohol use. The primary role of the FMCSA Clearinghouse is heightened safety. The database will allow employers increased insight and real-time access to reported violations for new and existing employees and it will become more difficult for drivers to conceal drug and alcohol violations from employers during the pre-employment investigation or hiring process. For more information, contact US Drug Test Centers today!

Who is required to enroll in the Clearing House?

- Drivers who hold Commercial Driver's Licenses (CDLs) performing safety-sensitive duties.
- DOT-regulated employers of such CDL drivers who operate commercial motor vehicles (CMVs)
- Student drivers who hold Commercial Learner's Permits (CLPs) and are training to perform safety-sensitive duties.
- Consortia/third-party administrators (C/TPAs) managing FMCSA-regulated employers and drivers or owner operators.
