Clearinghouse Services for DOT Compliance
About Interstate Consortium
Stay on top of FMCSA requirements with expert support for driver queries, reporting, and complete program management.
If you hire drivers with a Commercial Driver’s License (CDL) or operate a Commercial Motor Vehicle (CMV), you must stay compliant with the Clearinghouse Services regulations. The FMCSA Drug and Alcohol Clearinghouse helps track drug and alcohol violations, ensuring your drivers are safe and eligible. At Interstate Consortium, we provide comprehensive DOT clearinghouse services to help you manage your compliance requirements with ease and confidence.
What Are Clearinghouse Services?
Clearinghouse services help you follow DOT rules for drug and alcohol testing. If you hire CDL drivers, you must use the Clearinghouse to check their records and report any violations. Whether you’re an owner-operator or run a large fleet, Interstate Consortium makes sure you meet all Clearinghouse requirements.
Our services include:
- Pre-employment and annual queries
- Reporting drug or alcohol program violations
- Assisting with return-to-duty tracking
- Integration with Medical Review Officers (MROs) and Substance Abuse Professionals (SAPs)
- Support for Consortia/Third Party Administrators (C/TPAs)
Stay Compliant with the FMCSA Drug and Alcohol Clearinghouse
The Federal Motor Carrier Safety Administration (FMCSA) requires all employers, service agents, and drivers to use the Clearinghouse. You must query the Clearinghouse before hiring a driver and at least once every 12 months for each existing driver. If a driver fails a test or violates the alcohol testing program, the employer must report to the Clearinghouse immediately.
Interstate Consortium helps you complete these steps correctly and on time. We work directly with service agents, C/TPAs, MROs, and SAPs to keep your records clean and compliant.
Who Needs These Services ?
- Owner-operators who operate under their authority
- Fleet managers with CDL drivers
- Employers of anyone who must operate a commercial motor vehicle (CMV)
- Medical Review Officers, SAPs, and other third-party administrators
 Even if you’re not sure where to start, we’ll guide you through registration, data submission, and managing drug and alcohol program results.
Avoid Fines and Protect Your CDL Drivers
Failure to comply with drug and alcohol clearinghouse rules can lead to audits, fines, and disqualification from operating. Such risks can lead to serious consequences for your business. Our clearinghouse services ensure your drivers remain qualified and your business avoids penalties.


If a driver has violated a DOT drug and alcohol rule, we assist in managing their return-to-duty process, which includes required testing and coordination with Substance Abuse Professionals (SAPs). We also monitor timelines so you never miss a report.
