Random Drug & Alcohol Testing Program
FMCSA - FAA - USCG - FTA - FRA - PHMSA

All Random Test Fees Included


A DOT physical is an extensive health assessment mandated by the Department of Transportation (DOT) for all operators of commercial motor vehicles (CMVs). This evaluation ensures drivers possess the necessary physical, mental, and emotional stability to safely handle large vehicles on the roads. Conducted by a certified medical examiner (CME) registered with the National Registry of Certified Medical Examiners (NRCME), clearing this exam grants drivers a DOT medical certificate (also known as a DOT medical card), essential for retaining a valid CDL license as per FMCSA guidelines. For guidance on the required DOT physical if you fall under another DOT agency's jurisdiction, call 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.
