Federal Motor Carrier Safety Regulation 382

The CLEARINGHOUSE is a federal database which collects, stores, archives data pertaining to CDL drivers' drug and alcohol test results and makes it available for federal and state agencies. It is a centralized system that gives agencies, testing laboratories, state DOTs, state troopers and trucking companies access to a CDL driver's testing data.

In the past, there was no system where pre-employment, random and post-accident follow-up or reasonable suspicion test results were stored. Previously, test results were stored in a Consortium/Third Party Administrator (Random Program Administrator) data files and made available to the DOT only when the DOT requested it, which was rarely, and usually due to an accident or during a DOT Audit. Now, this data is available right away to everyone by requesting queries once a driver completes a test.

Registration in the Clearinghouse is a Federally-required mandate.

The sign-up deadline was January 6, 2020.

Enforcement (for now) is only via a compliance review or a DOT Audit or Post-Accident review and is coming soon to Roadside Inspections by state troopers on daily basis.

Questions & Answers

What is the Drug and Alcohol Clearinghouse (Clearinghouse) and what information does it contain?

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.

How will State Driver Licensing Agencies (SDLAs) use the Clearinghouse?

SDLAs will be able to query the Clearinghouse prior to completing licensing transactions, such as the issuance, renewal, transfer, and upgrade of a commercial driver’s license (CDL). The Federal Motor Carrier Safety Administration (FMCSA) has extended the compliance date for the requirement established by the Clearinghouse final rule that States query the Clearinghouse before completing certain CDL transactions. The SDLAs’ mandatory compliance with this requirement, currently due to begin on January 6, 2020, is delayed until January 6, 2023. SDLAs currently have the option to voluntarily query the Clearinghouse.

May drivers access their own information in the Clearinghouse?

Yes. Once a driver has registered in the Clearinghouse, he or she will be able to access his or her Clearinghouse record electronically, at no cost. This record would include any drug and alcohol program violation information available in the Clearinghouse, along with the status of their return-to-duty (RTD) process, if applicable.
