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

A C/TPA is a service provider that oversees either part or all of an employer's drug and alcohol testing program, coordinating random testing pools according to 49 CFR part 40 regulations.

Are random testing percentages always fixed or variable?

The rates for DOT random testing can fluctuate each year depending on the positivity rate; however, within our consortium, every DOT random testing fee is covered, regardless of the rate.

What occurs when I'm notified for a random test?

ADT will inform the company DER or Owner Operator via email/phone with details about the nearest testing location and guide them on the necessary steps. Once informed, the selected individual must promptly head to the testing site.

What substances are screened in a DOT drug test?

The DOT drug test checks for a DOT 5-panel urine and conducts a DOT breath alcohol test. It is essential that all tests are performed using a Federal CCF form alongside a Federal Alcohol Testing Form.

Assistance available during a DOT audit or inspection?

Yes, ADT can help organize imperative documentation like pre-employment tests, proof of random pool membership, supervisor training certificates, DOT policy development, and MIS reports.
