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
  • FMCSA Clearinghouse registration assistance

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.

Accredited has been wonderful to work with! My court ordered tests are on a very strange schedule but every time I call, they are quick to schedule me and are always able to find a location that works for where I’m at and when! Thank you for making this rather undesirable situation less stressful and efficient.

Madison Sanderford - 8/19/2024

Super Helpful

Detricia was super helpful in making sure that the drug test is sent my worker for was the right one I needed for my company to be compliant with my customers drug test requirements.

Kevin Howell - 12/19/2024

This is by far the easiest

This is by far the easiest way to get my lab work ordered and paid for. The phone calls are short and to the point. They don’t try to push extra sales on you and when I walk in to the clinic I simply show my donor pass and with in a matter of minutes I’m done. I will continue to use ADT in the future.
