Frequently Asked Questions

What is the FMCSA Clearinghouse and what information does it contain?

The Drug & Alcohol Clearinghouse is a secure, real-time online database used by the FMCSA, employers, State Driver Licensing Agencies (SDLAs), and law enforcement. It tracks DOT drug and alcohol violations, including positive test results, refusals to test, return-to-duty statuses, and follow-up testing completion for CDL and CLP holders.

Who must register and use the Clearinghouse?

Employers with CDL/CLP drivers performing safety-sensitive functions
Drivers, if they have violations or need to consent to pre-employment queries
Owner-operators, who must register and designate a C/TPA to manage reporting
C/TPAs, MROs, and SAPs, who are responsible for entering and managing data related to violations and treatment progress

When should employers query the Clearinghouse?

Pre-employment: Employers must perform a full query (with driver consent) before a CDL driver can perform safety-sensitive duties
Annually: At least one limited query must be conducted per year on each current CDL driver.
Limited queries reveal if information exists in the Clearinghouse. If it does, a full query must follow to review the details.

What employer actions must be reported—and when?

Employers are required to report specific events within three business days, including:

Verified positive drug or alcohol test results
Refusals to test (based on employer-determined circumstances)
Completion of return-to-duty negative test
Successful completion of follow-up testing requirements
These reports help keep the Clearinghouse up to date with a driver’s eligibility status.

What happens if a driver is “prohibited”?

A driver with a “prohibited” status in the Clearinghouse is not permitted to operate a commercial motor vehicle.

Their CDL/CLP cannot be issued or renewed by the state
The driver must complete the full DOT return-to-duty process, including evaluation by a Substance Abuse Professional (SAP), a negative return-to-duty test, and a prescribed follow-up testing schedule
Only once these steps are completed and reported will the driver be cleared to return to duty
