DOT physical exams are thorough medical checks mandated by the Department of Transportation for drivers of commercial vehicles. These exams are vital to confirm drivers have the physical, mental, and emotional ability to drive on public roads safely.

A passing result earns a DOT Medical Certificate, required for holding a CDL under FMCSA rules. For inquiries about specific DOT exams, call 800-221-4291.
