FMCSA Clearinghouse Registration for Drivers

The FMCSA Clearinghouse is a secure database developed to help identify CDL drivers who have violated terms of the DOT’s alcohol and drug testing program. Additionally, the FMCSA Clearinghouse contains information regarding whether commercial drivers have completed the DOT’s return-to-duty process.

Established in 2012 as part of the Moving Ahead for Progress in the 21st Century Act, the FMCSA Clearinghouse recently enacted new guidelines. Safety-sensitive employers and CDL drivers must register with the FMCSA Clearinghouse and abide by two obligations: driver “Queries” and “Reporting”.

NEW–Employer Reporting and Registration Obligations

Covered employers must now submit the following information to the FMCSA Clearinghouse within three business days of obtaining results:

  • CDL holders who refuse to complete FMCSA drug and/or alcohol tests
  • CDL holders with FMCSA drug test results that have been substituted or adulterated
  • Alcohol tests with concentrations of 0.04 or over for CDL drivers

Query Requirements

Another new FMCSA Clearinghouse rule involves employers who want to make queries about employees and applicants. The FMCSA Clearinghouse has set a flat rate and bundle option for high-volume users for performing either limited or full queries.

How Do Commercial Drivers Register with FMCSA Clearinghouse?

Commercial vehicle drivers must register before they are able to respond to consent requests submitted by a prospective employer. Additionally, unregistered drivers will not have access to their Clearinghouse records to review and initiate revisions or removal of incorrect information.

Drivers eligible to register must hold a commercial learner’s permit or a commercial driver’s license. More information about how to register can be found here.
