What Is the FMCSA Clearinghouse?
The Clearinghouse is managed by the Federal Motor Carrier Safety Administration and requires employers and drivers to:
- Register in the Clearinghouse
- Conduct pre-employment full queries
- Perform annual limited queries on current drivers
- Report DOT drug and alcohol violations
- Track return-to-duty and follow-up testing status
Failure to comply can result in out-of-service orders, enforcement actions, and civil penalties.
Who Must Comply?
This requirement applies to:
- Motor carriers employing CDL drivers
- Owner-operators (even with one CDL)
- Employers hiring CDL drivers into safety-sensitive positions
There is no minimum fleet size exemption.
How Crossroads Assists With Clearinghouse Compliance
- Clearinghouse Registration & Setup
Crossroads helps ensure:
- Proper account creation
- Correct role selection (employer vs. owner-operator)
- Drivers are correctly linked to the employer account
- Crossroads is designated as your C/TPA when applicable
This prevents common setup errors that delay hiring or cause audit issues.
- Clearinghouse Support for Owner-Operators
Owner-operators must act as both employer and driver, which is a frequent source of non-compliance.
Crossroads assists owner-operators with:
- Correct employer-driver registration
- Enrollment in a DOT random consortium (required even with one CDL)
- Completion of Clearinghouse queries
- Understanding annual query obligations
- Maintaining documentation for inspections and audits
- Pre-Employment & Annual Queries
We assist with:
- Full Clearinghouse queries before hiring
- Annual limited queries for existing drivers
- Driver consent workflows
- Record retention for FMCSA audits
No driver should be hired or remain active without proper Clearinghouse clearance.
- Violation Reporting & Post-Violation Guidance
When a DOT drug or alcohol violation occurs, Crossroads provides guidance on:
- Who must report the violation and when
- Coordinating with the Medical Review Officer (MRO)
- Understanding the next compliance steps
Accurate and timely reporting is critical to avoid enforcement action.
- Return-to-Duty & Follow-Up Tracking
Crossroads helps ensure:
- SAP referral coordination
- Return-to-duty testing completion
- Follow-up testing schedules are tracked
- Clearinghouse records reflect a compliant status
This protects employers from unknowingly allowing prohibited drivers to perform safety-sensitive duties.
- Clearinghouse + DOT Consortium Services
Clearinghouse compliance does not replace DOT testing requirements. Crossroads also provides:
- FMCSA-compliant random consortium enrollment
- Random testing administration
- On-site and mobile DOT testing (not instant testing)
- Recordkeeping and audit support
Your Clearinghouse activity and testing records stay aligned.
