Drug and Alcohol Clearinghouse Status and CDL Downgrades

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 the commercial driving privileges from the driver's license of an individual subject to the CMV driving prohibition. This would result in a downgrade of the license until the driver completes the return-to-duty (RTD) process. Note: SDLAs with legislative authority currently have the option to voluntarily query the Clearinghouse and downgrade CDLs for prohibited drivers and may do so before the November 18, 2024 compliance date.

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.
