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.

Dealing with allegation’s of drug use that completely false is stressful, ADT was able to get me the best tests, going back the farthest in the same day with as little hassle as possible, I spoke with 1 person and wasn’t transferred once, and they took my payment, and got me my work order for a clinic as close as possible for the service I needed. 5*

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.
