A completed application and a medical examiner's certificate are required to obtain a DOT medical card, according to the Federal Motor Carrier Safety Administration. Depending on the condition of an applicant's health at the time of the examination, additional forms may be required.
DOT medical cards are only required for individuals holding a commercial driver's license with the intent of operating a vehicle weighing 10,000 lbs or more, explains the FMCSA. Only doctors listed in the FMCSA National Registry of Certified Medical Examiners are permitted to examine CDL holders for the purposes of obtaining a DOT medical card.
The medical examination includes tests for blood pressure, blood sugar and vision, in addition to a general health check. If a person is diabetic or has high blood pressure, and if he takes medications for either condition, the DOT requires an additional application for exemption, which is filled out in part by the doctor conducting the exam. A drug test is not standard with the exam, notes the FMCSA, but may be requested by the medical examiner.
If a health problem such as high blood pressure or high blood sugar is discovered, a three-month exemption is issued in order to give the person time to treat and correct the health condition, according the FMCSA. After three months, another exam is required before a two-year DOT medical card is issued.
