Random Drug & Alcohol Testing Program

All Random Test Fees Included


DOT physicals are detailed medical check-ups mandated by the Department of Transportation for all commercial vehicle operators. These exams confirm that drivers are duly equipped physically, mentally, and emotionally to manage large vehicles on public highways. A certified medical examiner, listed on the National Registry of Certified Medical Examiners, conducts the exam. A successful assessment provides drivers with the DOT medical certificate, essential for keeping a CDL under FMCSA rules. If you need help figuring out the needed DOT physical or fall under another DOT authority, reach out to us at 800-221-4291.

  • We offer 1, 2 and 3 year memberships (multi-year discounts)
  • All random selection testing and testing fees included (no hidden costs)
  • MIS report at year-end and upon request
  • DER support, Clearinghouse assistance (FMCSA), DOT Physicals, MVR Reports & Supervisor Training

Why is a DOT Consortium Required?

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.
