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.

Answer: A consortium C/TPA refers to a service provider that oversees parts or all of an employer's drug and alcohol testing initiatives, managing the random testing pools and fulfilling compliance requirements dictated by 49 CFR part 40.
Are random testing percentages always the same or do they change?
Answer: The rates for DOT random testing can fluctuate yearly depending on the positivity rates. However, within our consortium, all fees related to DOT random testing are covered regardless of these rate changes.
What happens when I am selected for a random test?
Answer: ADT will inform the Designated Employer Representative (DER) or the Owner Operator via email or phone, indicating the nearest testing venue and necessary instructions. The chosen employee should proceed directly to the testing center upon notification.
What drugs are tested on a DOT drug test?
Answer: A DOT drug test evaluates controlled substances using a DOT 5-panel urine test along with a DOT breath alcohol test. It's crucial to perform all tests on a Federal CCF and Federal Alcohol Testing Form.
