FMCSA Drug and Alcohol Clearinghouse Registration: Step-by-Step Guide for New Carriers
The FMCSA Drug and Alcohol Clearinghouse went live in January 2020 and changed how every carrier hires CDL drivers. You cannot legally put a CDL driver behind the wheel without first registering as an employer in the Clearinghouse, running a full pre-employment query, and getting back a result. This is one of the most-missed items in new entrant audits. Here is exactly how to set it up.
What the Clearinghouse is
The Clearinghouse is a federal database, codified at 49 CFR Part 382 Subpart G, that tracks drug and alcohol program violations for CDL holders -- positive tests, refusals, return-to-duty steps, and successful completion of follow-up testing. It exists so that a driver cannot quietly switch employers after testing positive at one carrier.
Who has to register
Every motor carrier that employs CDL drivers in safety-sensitive positions must register as an employer. That includes:
- Owner-operators with their own MC number (you must register as both employer and driver)
- Small fleets with any CDL drivers
- Larger fleets
- Carriers that contract with a Consortium/Third Party Administrator (the C/TPA can act as your Clearinghouse designated representative, but you must still be registered)
Step-by-step employer registration
Create a Login.gov account
All Clearinghouse access goes through Login.gov. Set up an account at login.gov with two-factor authentication.
Go to clearinghouse.fmcsa.dot.gov and select 'Register'
Choose the role of Employer. The system asks whether you are a carrier or a service agent -- carriers select carrier.
Enter company information
Provide your legal business name, DBA if applicable, USDOT number, MC number, address, and main point of contact.
Designate a Consortium/TPA (optional but recommended)
If you work with a C/TPA, designate them in the system so they can submit information and conduct queries on your behalf.
Purchase query credits
Pre-employment and annual queries cost a small per-query fee. Buy a bundle in advance so you are not delayed when a driver is ready to start.
Two types of queries
Full query
Required as a pre-employment query for every new CDL driver. The driver must consent in the Clearinghouse before you can run it. Returns all reportable violations and their resolution status.
Limited query
Used annually for every CDL driver. Tells you only whether there is information in the Clearinghouse that would require a full query. The driver consents outside the Clearinghouse (in writing). If the limited query indicates information exists, you have 24 hours to obtain consent and run a full query.
Driver registration
Drivers themselves must register separately to consent to full queries. They use their own Login.gov account and link their CDL. As an employer you cannot consent on the driver's behalf. Plan ahead: the day you offer a driver a position, send them the Clearinghouse registration link.
Reporting obligations
Employers must report certain events to the Clearinghouse, including:
- Actual knowledge of a driver's drug or alcohol use
- A negative return-to-duty test result for a driver who previously tested positive
- Completion of follow-up testing
- Refusals to test that you observe directly
Most positive test results are reported by your Medical Review Officer (MRO) on your behalf, but you remain responsible for confirming the reporting was done.
Annual query reminder
You must run a limited query on every CDL driver at least once per year. Set a calendar reminder. Missing annual queries is a recurring audit finding.
Common Clearinghouse mistakes
- Letting a driver dispatch before the pre-employment full query result returns
- Forgetting to register the company as an employer because the owner thinks the C/TPA already did it
- Skipping annual limited queries
- Failing to obtain written driver consent for limited queries before running them
