You're only in violation if you fail to register and need to either conduct a query or report information to the Clearinghouse. Not registering in itself in not a violation. If you do not plan to hire anyone on or after January 6, 2020 you can wait to register until such time as you need to report information or conduct a query. You can email questions to 


If you do need to hire, report information or conduct a DACH inquiry, FMCSA suggest that you register directly at the DACH website at as an interim step until the FMCSA Portal is fully operational. Note that the DACH is also experiencing a high volume of calls, so you may be asked to leave a message for a call-back.


You are able to register for a Clearinghouse account at this time without linking to your Portal account. However, at a time in the future, you will still need to link your Clearinghouse account to your Portal account when all functionality is re-established.

D & A Clearinghouse

The Drug & Alcohol Clearinghouse registration is mandatory for all employers of CDL drivers and Owner-Operators. Scroll down for registration information. 

If your company has a USDOT number, you must first setup an FMCSA Portal account before trying to register for the Clearinghouse. If you already have a FMCSA Portal account, use the instructions below to configure your account to grant access to the Clearinghouse. 


REMINDER: You need to purchase a "Query Plan" so TNT can run drivers through the system, the plans never expire, most have been purchasing the 10 or 20 plan. 


FMCSA Portal: 



Configuring FMCSA Portal

Once you’ve setup your FMCSA Portal account you’ll need to login and grant access or permission to the clearinghouse following these steps:

  1. Click “Account Management”, upper left
  2. Click “My Profile
  3. Click “Portal Roles/USDOT#” Tab
  4. Click on your DOT #
  5. Under “Available Roles” select “DACH Motor Carrier Admin” and then click “Add Role”
  6. Under “Available Roles” select “DACH Motor Carrier” and the click “Add Role”


You should see both listed as “pending” under “Requested Roles”, you’ll have to logout and wait 5-10 minutes for FMCSA to “approve” the roles. You might need to logout and log back in. 


To check approval, repeat steps 1-3, under “Requested Roles” you should now see “DACH Motor Carrier Admin – Approved” and “DACH Motor Carrier – Approved”. If you don't see "approved" try again, FYI make sure you click on "submit". 


If you are experiencing difficulties that are preventing you from linking to your Portal account in the Clearinghouse, please contact the FMCSA Portal Registration Call Center at 800-724-2811. The Portal Registration Call Center’s hours of operation are Monday thru Friday 8:00 a.m.-8:00 

FMCSA Portal Account Issues!

After you've setup your FMCSA Portal account and you get a "blank page" when trying to login and you see "" in the URL field FMCSA says they're aware of this error and currently the only fix is to contact FMCSA and have them delete your account, then have you create a new one. 


I've found that the fastest way to contact FMCSA is by using the online chat feature. Here's a link that will take you directly to the FMCSA chat page
