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.

Yes. The Clearinghouse will identify drivers who move frequently and obtain CDLs in different States and link those CDLs, in order to maintain complete and accurate information on such drivers.

No, the final rule does not change any existing requirements in the U.S. Department of Transportation (DOT)-wide procedures for transportation workplace drug and alcohol testing.

Employers, drivers, medical review officers (MROs), substance abuse professionals (SAPs), and consortia/third-party administrators (C/TPAs) must register in the Clearinghouse to access the Clearinghouse.

Instructional job aids are available for:

• Employers with Portal accounts
• Employers without Portal accounts
• CDL drivers
• Consortia/third-party administrators
• Medical review officers
• Substance abuse professionals

Employers, C/TPAs, MROs, and SAPs can also invite users to complete required actions in the Clearinghouse on their behalf. These users would register as Clearinghouse Assistants.

Drivers are not required to register for the Clearinghouse. However, a driver will need to be registered to provide electronic consent in the Clearinghouse if a prospective or current employer needs to conduct a full query of the driver’s Clearinghouse record—this includes all pre-employment queries.

A driver must also be registered to electronically view the information in his or her own Clearinghouse record.

Registered drivers will have their Clearinghouse accounts and contact preferences set up, allowing them to quickly respond to query requests from employers. Registration is available at https://clearinghouse.fmcsa.dot.gov/register.
