The Drug and Alcohol Clearinghouse (DACH) is a secure online database operated by the Federal Motor Carrier Safety Administration (FMCSA). DACH provides employers, state driver licensing agencies, and state law enforcement personnel real-time information about Commercial Driver’s License (CDL) and Commercial Learner’s Permit (CLP) holders’ drug and alcohol program violations.
The DACH contains records of drug and alcohol prohibition violations, including positive drug or alcohol test results and test refusals. When a driver completes the return-to-duty process and follow-up testing plan, this information will be recorded in the Clearinghouse.
Drivers holding CLPs or CDLs are subject to this federal requirement and should be registering with the DACH. Non-CDL holders and their employers are not subject to DACH requirements and should not be registering with the Clearinghouse.
DRUG AND ALCOHOL CLEARINGHOUSE STATUS AND CDL DISQUALIFICATION
As established in the first Clearinghouse final rule, drivers with a “prohibited” Clearinghouse status are prohibited from operating a Commercial Motor Vehicle (CMV) on public roads. The second Clearinghouse final rule (Clearinghouse-II) further supports this by ensuring that drivers with a “prohibited” Clearinghouse status do not continue to hold a Commercial Driver’s License (CDL) or Commercial Learner’s Permit (CLP).
Beginning November 18, 2024, State Driver Licensing Agencies (SDLAs) will be required to remove commercial driving privileges from the Driver's License of an individual subject to the CMV driving prohibition. This would result in the license being disqualified until the driver completes the return-to-duty (RTD) process.
Return to Duty
If a CDL holder is in a prohibited status and wishes to return to duty, they must complete the Return to Duty Process. Find out more information about the Return to Duty Process.
DACH is an FMCSA program that is not administered by the Vermont DMV. For more information, visit the FMCSA clearinghouse website or call the FMCSA information line at 1-800-832-5660.
