One of the mandatory rules that the Federal Government has issued is that all the drivers of commercial vehicles must have a CDL or the Commercial Driver’s License. Besides this license, the commercial vehicle drivers must also possess a pass certificate of the physical exam for health conducted by the Department of Transportation or DOT. According to the guidelines issued by the Federal Government, the physical examination for health must be done by a medical examiner who is certified and who is listed in the Federal Registry. There are many medical centers assigned by the Federal Government to conduct the physical examination of the commercial vehicle drivers for health and the Charlotte NC DOT Exams centers are one of them.
