**New Requirement – Commercial Drivers / Learner Permit Holders
Beginning October 21, 2024, all Commercial Driver License (CDL) holders and applicants for a CDL or Commercial Learner’s Permit (CLP) must register to the Federal Motor Carrier Safety Administration, Drug and Alcohol Clearinghouse (Clearinghouse).
The Clearinghouse is a secure online database that tracks violations of the U.S. Department of Transportation drug and alcohol testing program for CDL and CLP holders. DMV will be checking your status prior to any CDL or CLP transaction.
All states will be required to remove the commercial driving privileges of drivers in a “prohibited” status in the Clearinghouse, by downgrading the CDL or cancelling the CLP.
Drivers in a “prohibited” status in the Clearinghouse must complete the return-to-duty (RTD) process and have a not-prohibited status in the Clearinghouse to upgrade a CDL or become eligible for a CDL or CLP. For more information about the RTD process, please click on the link below:
