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.

Testing & Results: Visit the assigned testing center. ADT will manage CCFs, lab processing, and reporting.

DOT random testing rates may fluctuate annually based on the positivity rate; however, in our consortium, regardless of the random testing rate, all DOT random testing fees are accommodated.
What happens when I am selected for a random test?
ADT will notify the company's DER or Owner Operator via email or phone with the nearest testing location and instructions. The selected individual must proceed to the testing center immediately upon notification.
What drugs are tested on a DOT drug test?
A DOT drug test includes a DOT 5 panel urine test and a DOT breath alcohol test. It's important to ensure tests are conducted using a Federal CCF and Federal Alcohol Testing Form.
