DOT CONSORTIUM ENROLLMENT - Gonzales, TX

Random Drug & Alcohol Testing Program

All Random Test Fees Included


A DOT physical examination is an all-encompassing health check mandated by the Department of Transportation for every commercial motor vehicle driver. This exam ensures that drivers are in sound physical, mental, and emotional health to safely manage large vehicles on roads. A certified medical examiner from the National Registry conducts the test. Success leads to obtaining a DOT medical certificate, which is essential for keeping a valid CDL under FMCSA rules. If regulated by another DOT body and need guidance on the required DOT physical, please 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.
