The DOT Drug & Alcohol Clearinghouse

The DOT Drug & Alcohol Clearinghouse arrives soon: January 6, 2020! 

What exactly is it?

An online database providing employers, licensing agencies, and enforcement officers with real-time information about truck and bus drivers who have violated DOT drug or alcohol testing rules. Employers must check the Clearinghouse when hiring each new CDL driver and every year for existing CDL drivers like you. The Clearinghouse will affect you in several ways:


1.) You will need to register on the Clearinghouse website (available Fall 2019) in order to comply with item #2 below. Registration is optional unless you switch employers or have a DOT drug or alcohol violation. Registration will give you free access to your own Clearinghouse record.

2.) You will need to go to the Clearinghouse to grant electronic consent whenever your employer is required to purchase a full Clearinghouse report on you. You will not be allowed to continue operating a commercial motor vehicle (CMV) or perform other safety-sensitive duties if you refuse to grant this consent (§382.703(c)).

3.) You will need to sign a separate consent form (annually or one-time) to allow your employer to obtain “limited” Clearinghouse reports that indicate whether there is information about you in the
Clearinghouse (if there is, then a full report will be required – see #2 above) (§382.701(b)).

4.) If you commit any of the following DOT violations or complete any of the following steps after January 6, 2020, it will be reported to the Clearinghouse:

  • Any verified positive, adulterated, or substituted drug test
  • Any confirmed alcohol test result of 0.04 or higher
  • Any refusal to submit to a DOT-required test
  • Any verified and documented “actual knowledge” that you violated the drug/alcohol rules:
    – Any on-duty alcohol use, including any citation for DUI/DWI while driving a CMV
    – Any alcohol use within 4 hours before going on duty
    – Any alcohol use within 8 hours of an accident or before a post-accident test is complete (whichever occurs first)
    – Any prohibited drug use while on duty
  • Successful completion of the return-to-duty process following treatment*
  • Any negative return-to-duty test*
  • Successful completion of follow-up testing*

*Only reported if the underlying violation occurred after January 6, 2020.

5.) You will be notified whenever information about you in the Clearinghouse is added, removed, or revised. You can specify how you want to be contacted when you register.
