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.

  • 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 defines a DOT Consortium (C/TPA), and who needs this service?

A consortium C/TPA acts as a service representative overseeing an employer's drug and alcohol testing protocols, which encompass random testing pools and compliance tasks as per 49 CFR Part 40.

Do random testing percentages remain fixed, or do they fluctuate?

Random testing rates dictated by the DOT might adjust annually, depending on positivity rates. In our consortium, however, the fees for random testing remain unchanged, irrespective of rate adjustments.

What procedure follows a random test selection?

Upon selection for a random test, ADT contacts the company DER or Owner Operator via email/phone, providing them the nearest test site and specific instructions. Immediate action from the selected employee to the testing center is required following notification.

Which substances are subject to testing in a DOT drug test?

DOT drug tests screen for a standard DOT 5-panel urine and include a DOT breath alcohol test. It is essential that all tests utilize a Federal CCF and Federal Alcohol Testing Form.

Can you assist in the event of a DOT audit or inspection?

Absolutely! ADT is equipped to organize necessary documentation, such as pre-employment tests, confirmation of random pool enrollment, supervisor training certificates, DOT policy development, and MIS reports.

How frequently may I update my employee pool?

We facilitate updates to employee rosters quarterly, though employers are at liberty to modify their list of covered employees at any point prior to selection dates.
