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.

What is a DOT Consortium (C/TPA) and who requires it?

Are random testing rates consistent, or can they vary?
The DOT's random testing percentages can fluctuate annually depending on positivity rates. Despite any changes in random testing percentages, our consortium covers all DOT random testing costs.
What occurs when selected for a random test?
ADT informs the Designated Employer Representative (DER) or Owner Operator by email or phone, providing the nearest testing location and further instructions. The employee must proceed immediately to the testing center upon receiving the notification.
What substances are screened in a DOT drug test?
A DOT drug test evaluates for a DOT 5-panel urine as well as a breath alcohol test. All these tests must utilize a Federal Custody and Control Form and Federal Alcohol Testing Form.

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.
