Drug and Alcohol Clearinghouse Requirements

What Is the FMCSA Clearinghouse?

The FMCSA Drug and Alcohol Clearinghouse is a secure online database that tracks commercial driver drug and alcohol program violations. Launched on January 6, 2020, the Clearinghouse provides FMCSA, employers, and state licensing agencies with real-time access to information about CDL holders who have violated federal drug and alcohol testing requirements. Before the Clearinghouse, a driver who tested positive could simply move to a new employer without disclosing the violation. The Clearinghouse closes that loophole by creating a centralized record that follows the driver regardless of employment changes.

Who Must Register?

Three groups are required to register with the Clearinghouse:

• Employers: All motor carriers and other entities subject to FMCSA drug and alcohol testing regulations must register to conduct queries and report violations
• CDL drivers: Drivers must register to provide electronic consent for full queries and to access their own Clearinghouse records
• Medical Review Officers (MROs), Substance Abuse Professionals (SAPs), and third-party administrators (C/TPAs): These entities must register to report violations and return-to-duty results

Employer Query Requirements

Employers have two types of queries available:

Pre-Employment Full Query

Before hiring a CDL driver, employers must conduct a full query of the Clearinghouse to check for any unresolved drug or alcohol violations. A full query requires the driver's electronic consent through the Clearinghouse system. Employers may not hire a driver who has an unresolved violation in the Clearinghouse.

Annual Limited Query

Employers must conduct a limited query at least once per year for every CDL driver they employ. A limited query reveals only whether the Clearinghouse contains any records for the driver, without providing details. The driver must provide general consent (which can cover multiple years) for limited queries. If a limited query returns a result indicating records exist, the employer must promptly conduct a full query to obtain the details.

What Gets Reported to the Clearinghouse

The following violations and actions must be reported:

• Positive drug test results (reported by the MRO)
• Positive alcohol test results with a BAC of 0.04 or higher (reported by the employer)
• Refusals to test (reported by the employer or MRO depending on the type of refusal)
• Drug and alcohol violations identified by state enforcement agencies
• Return-to-duty (RTD) test results (reported by the SAP and employer)
• Completion of follow-up testing plans (reported by the employer)
• Actual knowledge violations determined by the employer (operating under the influence, possession, use, or distribution of drugs or alcohol)

The Return-to-Duty Process

A driver with a Clearinghouse violation cannot return to safety-sensitive duties until completing the full return-to-duty (RTD) process:

1. SAP evaluation: The driver must be evaluated by a DOT-qualified Substance Abuse Professional who determines the appropriate treatment or education
2. Complete treatment: The driver must complete all treatment or education prescribed by the SAP
3. Follow-up SAP evaluation: The SAP must conduct a follow-up evaluation confirming the driver has complied with the treatment plan
4. Return-to-duty test: The driver must pass a return-to-duty drug and/or alcohol test under direct observation
5. Follow-up testing: The SAP must establish a follow-up testing plan of at least 6 directly observed tests in the first 12 months, with potential extension up to 60 months

State Licensing Agency Access

State Driver Licensing Agencies (SDLAs) have access to Clearinghouse records for purposes of issuing, renewing, upgrading, or transferring CDLs. States are required to query the Clearinghouse during CDL transactions and must not issue or renew a CDL for a driver with an unresolved Clearinghouse violation.

Penalties for Non-Compliance

Employers who fail to query the Clearinghouse as required, or who allow drivers with unresolved violations to operate, face significant enforcement risk. Violations of Clearinghouse requirements can result in civil penalties under FMCSA's enforcement authority and can also serve as evidence of negligent hiring in civil litigation.

Best Practices

Carriers should establish clear Clearinghouse policies and procedures, designate a Clearinghouse administrator, integrate query requirements into their hiring and annual review workflows, and maintain records of all queries and driver consents. Consistent Clearinghouse compliance is a fundamental element of a strong compliance program and helps protect your carrier's reputation on platforms like TruckCodes.
