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

DOT Consortium: Frequently Asked Questions

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

A Consortium/Third Party Administrator (C/TPA) acts as a service provider, managing full or partial aspects of an employer's drug and alcohol testing initiatives. This includes managing random testing pools and ensuring compliance with regulatory standards specified under 49 CFR part 40.

Do random testing rates remain constant, or do they vary?

The rates for DOT random tests may fluctuate annually according to the percentage rates of positivity. Nevertheless, in our consortium, regardless of any changes, all fees related to DOT random testing are covered.

What steps follow after I am selected for a random test?

ADT will inform the company's Designated Employee Representative (DER) or the Owner Operator using email or phone. We provide the nearest test location and specific instructions. Upon receiving this notification, the chosen employee must directly proceed to the testing site.

What substances are included in a DOT drug test?

The DOT drug test includes a DOT 5-panel urine screening and a DOT breath alcohol analysis. It is imperative to ensure every test is performed using a Federal Custody and Control Form and a Federal Alcohol Testing Form.

Can assistance be rendered during a DOT audit or inspection?

Indeed, ADT is equipped to collate essential documents, such as pre-employment tests, confirmations of random pool participation, supervisor training credentials, development of DOT policies, and MIS reports.

How frequently is it possible to refresh the employee pool?

We endorse employee pool updates on a quarterly basis. Employers can opt to include or exclude covered employees ahead of any selection cycle.
