Do You Still Have Access to Your Records?

The FMCSA Drug & Alcohol Clearinghouse goes into effect January 2020. However, the DOT requires you maintain records for the past 36 months in the correct format. In sum, until 2023, you'll need to have paperwork on hand for every driver on your team. 49 CFR Part 40 .pdf

WSS is experienced in helping employers become compliant and maintain compliance. With every update and even in the case of an audit, WSS will partner with you to increase safety and productivity and reduce liability.

Looking for a Consortium?

The Department of Transportation regulations allow for Consortiums to administrate random testing of regulated employees and comply with DOT standards. The WSS Consortium pools your regulated employees with employees from other companies in order to have a large enough base to test individuals equitably and without bias throughout the year.

Does the final rule change any of the existing drug and alcohol program requirements in Part 40?

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.

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

The Clearinghouse is a secure online database that will give 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 will contain 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 will also be recorded in the Clearinghouse.

If a driver has a drug and alcohol program violation in one State, then applies for a commercial driver’s license (CDL) in another State, will the Clearinghouse be able to connect that driver’s drug and alcohol violation history to the new CDL?

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.

How do authorized users sign up to access the Clearinghouse?

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.

Are CDL drivers required to register for the Clearinghouse?

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 record—this will include all pre-employment queries beginning on January 6, 2020.

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

Drivers who register before January 6, 2020, will have their Clearinghouse accounts and contact preferences set up, allowing them to quickly respond to query requests from employers on or after January 6, 2020. Registration is available at
