What Is the Drug and Alcohol Clearinghouse?

The Federal Motor Carrier Safety Administration (FMCSA) created the Drug and Alcohol Clearinghouse in 2020 to prevent truck drivers from hiding a failed pre-employment screening test by quickly applying for a new driving job before the failed test shows up on their driving record. Mandated by Congress, the Clearing House is a secure online database that tracks alcohol and drug offenses by CDL holders and Commercial Learner's Permit (CLP) holders. This centralized data hub empowers employers, law enforcement, and state agencies to monitor driver compliance with federal substance use regulations.

For carrier owners and fleet managers, the Drug and Alcohol Clearinghouse helps keep both safety and compliance regulators in check. It helps you ensure the drivers you hire and retain can safely and legally operate a commercial motor vehicle (CMV).

How the Clearinghouse Works

As we noted earlier, the Clearinghouse prevents drivers with drug or alcohol violations from slipping through the cracks — whether they're moving to a new employer or applying for a CDL in another state. It does this by allowing:

  • Employers to quickly verify each driver’s eligibility for safety-sensitive duties.
  • State Driver Licensing Agencies (SDLAs) to deny or revoke CDLs for non-compliance.
  • Law enforcement to identify drivers with outstanding violations.
  • The FMCSA to maintain national oversight.

Who Reports to the Clearinghouse?

What does the Drug and Alcohol Clearinghouse mean for carrier owners, fleet managers, and owner-operators? Reporting violations to the Clearinghouse isn't optional; it's required. The following parties must submit data:

  • FMCSA-regulated employers
  • Medical Review Officers (MROs)
  • Substance Abuse Professionals (SAPs)
  • Consortia/Third-Party Administrators (C/TPAs)

What violations do you need to report? Violations include:

  • Positive drug or alcohol test results
  • Refusals by drivers to test
  • Any other breaches of DOT's substance use regulations under 49 CFR Part 382.

Your Obligations: Pre-Employment and Annual Queries

If you're hiring a new CDL driver, you must query the Clearinghouse before they can start safety-sensitive duties. This ensures the driver isn't currently prohibited from operating a CMV due to an unresolved violation.

Already have drivers on the payroll? You're also required to run an annual query on each of your drivers to stay compliant. Without performing these annual checks, your company risks costly penalties.

Driver Consent Is Required Before Running a Query

A driver must provide electronic consent before a prospective or current employer can run a full query. If the driver refuses, you're legally prohibited from viewing detailed violation records, and the driver is prohibited from performing safety-sensitive functions.

  • You must run a Clearinghouse query for all new hires before they begin driving.
  • You are required to run an annual query on each existing driver.
  • Failure to comply may result in costly FMCSA penalties.

What to Do If a Violation Is Reported

If a violation is reported in the Clearinghouse, you must immediately remove the driver from safety-sensitive functions and follow FMCSA return-to-duty requirements.

  • Initiate the return-to-duty process as required by FMCSA regulations.
  • Ensure the driver completes evaluation and treatment with a Substance Abuse Professional (SAP), if needed.
  • Maintain documentation of all compliance steps taken.

Proper documentation and quick action protect your company and demonstrate your commitment to compliance and public safety.

Benefits of the Clearinghouse for Carriers

In addition to helping you cover your compliance bases, the Drug and Alcohol Clearinghouse is a powerful tool for managing risk. It helps you and your company:

  • Improve highway safety by keeping impaired drivers off the road
  • Streamline hiring with instant access to a driver's drug and alcohol history
  • Protect your brand and reputation by showing a proactive stance on safety
  • Prevent violations from being hidden when drivers change jobs or relocate

The Drug and Alcohol Clearinghouse is a critical part of the FMCSA's safety framework. It should also be part of your compliance strategy. Understanding how it works helps your business avoid costly violations and empowers you to build a fleet that's both compliant and dependable.
