The DOT Physical and truck driver medical qualifications for a CDL are discussed in this video. The DOT Physical is one of the most important qualifications for any CDL driver. Its purpose is intended to help ensure the safety of both the CDL holder and the other drivers sharing the road with him.

A medical examiner’s certificate, which is commonly known as a DOT medical card, provides proof the driver has meet the medical requirements to hold a CDL. In most states, a perspective CDL driver must hold a valid DOT medical card before a CDL learner's permit can be issued.
