Clearinghouse Update
Federal Motor Carrier Safety Adminsitration

Based on feedback we have received from drivers, employers, and service agents, FMCSA continues to make improvements to the registration process. Recently, the site was enhanced as follows.

Enhancements include:

  • A redesigned home page that highlights the “Register” and “Login” buttons, and offers an updated "Learn More" section with some quick links to find helpful information.
  • A new page called Before You Register listing information users will need to provide during registration, for each user role. This page also includes instructional job aids for each user role and information on creating a account.
  • A revised “Select Your Role” page that describes each Clearinghouse user role and the actions users with that role can take in the system.
  • •    Registration pages have been redesigned to improve use on mobile devices.

This system update also includes improvements to CDL verification. These enhancements will help with registration, conducting queries, and reporting violations.

How do I register?

Register today to ensure you are ready on January 6, 2020, when the Clearinghouse will be fully operational.

The U.S. DOT FMCSA Drug and Alcohol Clearinghouse is coming January 6, 2020 and you may be required to enroll. The Clearinghouse is a secure online database that will give employers, the 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. It can be accessed at  The Clearinghouse will enable employers to identify drivers who commit a drug and alcohol program violation while working for one employer, but who fail to subsequently inform another employer.

Beginning JANUARY 6, 2020 employers will be required to conduct both electronic queries and traditional manual inquiries with previous employers to meet the three-year timeframe, required by FMCSA’s drug and alcohol use testing program, for checking CDL driver violation histories. Once three years of violation data are stored in the Clearinghouse, employers are no longer required to also request information from the driver’s previous FMCSA-regulated employers.

The Clearinghouse requires FMCSA-regulated employers, medical review officers (MROs), substance abuse professionals (SAPs), consortia/third-party administrators (C/TPAs), and other service agents to report to the Clearinghouse information related to violations of the drug and alcohol regulations in 49 Code of Federal Regulations, Parts 40 and 382 by current and prospective employees. Drivers may also view their own records for information recorded on or after January 6, 2020.

EMPLOYERS MUST: Report drug and alcohol violations and check that no current or prospective employee is prohibited from performing safety-sensitive functions, such as operating a CMV, due to a drug and alcohol program violation for which a driver has not successfully completed a Return-To-Duty (RTD) process. Employers must annually query the Clearinghouse for each driver they currently employ.

CDL DRIVERS MUST: View own record, provide consent to current or prospective employers to access details about any drug and alcohol program violations, and select a Substance Abuse Professional, if needed.

MEDICAL REVIEW OFFICERS MUST: Report verified positive drug test results and test refusals.

SUBSTANCE ABUSE PROFESSIONALS MUST: Report RTD initial assessment and eligibility status for RTD testing.

CONSORTIUM/THIRD-PARTY ADMINISTRATORS MUST: On behalf of an employer, report drug and alcohol program violations and perform driver queries as required.

STATE DRIVER LICENSING AGENCIES MUST: Query the Clearinghouse prior to completing licensing transactions.
