Random Drug & Alcohol Testing Program
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
