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.

Greensboro Joseph - 11/19/2024

This is by far the easiest

This is by far the easiest way to get my lab work ordered and paid for. The phone calls are short and to the point. They don’t try to push extra sales on you and when I walk in to the clinic I simply show my donor pass and with in a matter of minutes I’m done. I will continue to use ADT in the future.
