The FMCSA Drug and Alcohol Clearinghouse is a national database of CDL drivers’ drug and alcohol program violations. It launched in January 2020.
What gets reported
- Positive drug tests and alcohol tests of 0.04 or higher
- Test refusals
- Actual knowledge violations reported by an employer
- Return to duty progress and completion
Who checks it
Employers must run a full query before hiring a CDL driver and a query at least once a year for current drivers. Since November 2024, state licensing agencies must also act on Clearinghouse records, and drivers in “prohibited” status lose their commercial driving privileges until they complete return to duty.
How long a violation stays
A violation stays in the Clearinghouse for five years or until you complete the return to duty process, whichever is later.
