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.
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.

DOT random testing percentages can shift annually depending on the rate of positive results, however, in our consortium, all required fees for random DOT testing are invariably covered, irrespective of the rate.
What should be expected if chosen for a random test?
Upon selection for a random test, ADT will contact either the company's Designated Employer Representative (DER) or the Owner-Operator through email or phone, providing the details of the nearest testing location and the necessary instructions. The chosen employee is required to visit the testing facility immediately after being notified.
What substances are included in a DOT drug test?
A DOT drug test includes a 5-panel urine test and a breath alcohol test. It is essential that these tests are administered using a Federal Custody and Control Form (CCF) and Federal Alcohol Testing Form.

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.
