The Clearinghouse is a secure online database that gives employers, the Federal Motor Carrier Safety Administration (FMCSA), State Driver Licensing Agencies (SDLAs), 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 Clearinghouse contains records of violations of drug and alcohol prohibitions in 49 CFR Part 382, Subpart B, including positive drug or alcohol test results and test refusals. When a driver completes the return-to-duty (RTD) process and follow-up testing plan, this information is also recorded in the Clearinghouse.
