FMCSA - FAA - USCG - FTA - FRA - PHMSA

All Random Test Fees Included


Our DOT Consortium Membership includes quarterly random selections, notifications by email & phone, testing site coordination, MIS reporting, and a Certificate of Compliance upon enrollment. Owner-operators DOT-regulated employers Certificate of Compliance.

  • We offer 1, 2 and 3 year memberships (multi-year discounts)
  • All random selection testing and testing fees included (no hidden costs)
  • MIS report at year-end and upon request
  • DER support, Clearinghouse assistance (FMCSA), DOT Physicals, MVR Reports & Supervisor Training

Why is a DOT Consortium Required?

Owner Operators- DOT requires all owner-operators to enroll in a consortium so they are included in a compliant random testing pool because they cannot randomly test themselves.

Small Employers-Some smaller companies may not have enough drivers or safety-sensitive employees to maintain their own statistically valid random pool. Therefore, by joining a consortium, they are combined with other companies to form a large pool that meets DOT testing requirements.

Large Employers-Larger fleets may manage their own random pool but often use a consortium/TPA to outsource the process, reduce administrative burden, and ensure strict compliance.

How Our DOT Consortium Works

Step 1: Enroll: Select a 1, 2, or 3 year membership and receive your Certificate of Compliance by email.

Quarterly Selections: We process our consortiums using a scientifically valid, computer-generated random draws each quarter.

Immediate Notifications: If selected, your DER receives email & phone notice with selection instructions.

Testing & Results: Visit the assigned testing center. ADT will manage CCFs, lab processing, and reporting.

MIS Reporting: Year-end and on-demand MIS reports included.

Included With Membership

  • All random selection test fees (drug & alcohol where applicable)
  • DER support & audit-ready documentation
  • Federal CCFs (5-part) for DOT drug tests
  • FMCSA Clearinghouse registration assistance
  • Policy templates (DOT Drug & Alcohol)

    Saved My CDL!

    Time was running out before my Cdl got downgraded because of a violation I had on clearinghouse. I couldn't find an employer to send me for my return to duty test, but these guys had my test scheduled and done in the same day! They saved my cdl. Thank you again!
