DOT CONSORTIUM ENROLLMENT - Modesto, CA

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

All Random Test Fees Included


A DOT physical examination, mandated by the Department of Transportation, is essential for all commercial motor vehicle drivers. This thorough checkup confirms that drivers are capable of operating large vehicles safely on public roads, both physically and mentally. Conducted by certified medical professionals listed in the National Registry, successfully passing this exam grants drivers the DOT medical certificate. This certificate is necessary for keeping a valid CDL license according to FMCSA standards. If you're governed by a different DOT authority and need guidance on which DOT physical applies to you, dial 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.
