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

DOT Consortium: Frequently Asked Questions

What defines a DOT Consortium (C/TPA), and who benefits from it?

A consortium C/TPA is an external service provider managing various components of an employer's drug and alcohol testing obligations, including the facilitation of random testing groups as mandated by 49 CFR part 40.

Do random testing quotas stay constant, or do they alter?

DOT random testing rates can vary yearly depending on positivity trends. Nevertheless, in our consortium, despite any adjustments in testing rates, all associated DOT random testing costs are fully covered.

What steps occur after random test selection?

Upon being chosen for a random test, the designated DER or Owner Operator will receive instructions via email or phone, detailing the nearest testing site. Subsequently, the selected personnel must proceed immediately to the facility once informed.

Which substances are screened in a DOT drug test?

DOT drug testing encompasses a 5-panel urine screen and a breath alcohol test. Ensure that all testing is conducted using a Federal CCF and Federal Alcohol Testing Form.

Can support be provided during a DOT inspection or review?

Indeed, ADT assists by organizing necessary documents, such as pre-employment testing records, random pool membership proofs, supervisor certificates, DOT policy drafts, and MIS reports.

How frequently can I revise my employee list?
