A DOT physical is a thorough medical check mandated by the Department of Transportation for commercial motor vehicle operators. This examination ascertains the driver's ability to handle large vehicles safely on public highways, ensuring they are fit physically, mentally, and emotionally. Conducted by certified medical examiners listed on the National Registry, passing this exam grants drivers a DOT medical certificate, vital for a CDL under FMCSA rules. For DOT agency-specific exam needs, call us at 800-221-4291.

  • 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.
