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

DOT Consortium: Frequently Asked Questions

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

A C/TPA, or consortium, is an agent that handles various aspects of an employer's drug and alcohol testing program, including the management of random testing pools and ensuring adherence to compliance obligations addressed in 49 CFR part 40.

Are random testing percentages constant, or can they vary?

The DOT's random testing percentages can fluctuate annually, depending on the rates of positive results; however, within our consortium, regardless of the random testing rate, all DOT random testing charges are encompassed.

What transpires when I am chosen for a random test?

ADT will inform the company Designated Employer Representative (DER) or Owner Operator through email or phone, providing the nearest test location and essential instructions. The chosen employee must head straight to the testing center upon notification.

Which substances are assessed in a DOT drug test?

A DOT drug examination includes a DOT 5-panel urine test and a DOT breath alcohol evaluation. It is crucial that all tests be executed using a Federal CCF and Federal Alcohol Testing Form.

Can you assist during a DOT audit or examination?

Indeed, ADT offers assistance by organizing necessary documentation such as pre-employment tests, proof of random pool enrollment, supervisor training certifications, DOT policy development, and MIS reports.
