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.

  • DER support & audit-ready documentation
  • Federal CCFs (5-part) for DOT drug tests

    • What is a DOT Consortium (C/TPA) and who needs it?

      A consortium C/TPA serves as a service agent to administer portions or the entirety of an employer's drug and alcohol testing program, which involves creating random testing pools and ensuring tasks are conducted in accordance with 49 CFR part 40.

    • Are random testing percentages always the same or do they change?

      The percentages for DOT random testing can fluctuate yearly based on positivity rates. Nevertheless, within our consortium, all fees related to DOT random testing are covered, regardless of rate changes.

    • What happens when I am selected for a random test?

      ADT will inform the company's Designated Employer Representative (DER) or the Owner-Operator through email or phone, detailing the nearest test location and required steps. The employee selected must head to the testing site promptly upon receiving notification.

    • What drugs are tested on a DOT drug test?

      A DOT drug test checks for substances using a DOT 5 panel urine test and a DOT breath alcohol test. It's crucial to ensure that each test is carried out using a Federal Chain of Custody Form (CCF) and a Federal Alcohol Testing Form.

    • Can you help during a DOT audit or inspection?

      Absolutely, ADT is able to coordinate the necessary documents such as pre-employment test results, evidence of random pool participation, supervisor training certifications, DOT policy formulation, and Management Information Systems (MIS) reports.
