Once the history and paper-based exam are completed, the next step in a DOT physical is testing your heart function, hearing, and vision. • In order to qualify for a DOT card, a driver requires a blood pressure reading that is below 140/90. The provider will take two readings, to ensure that the reported reading is as accurate as possible. At the same time, the provider will assess the pulse to make sure that it is steady and regular. • Vision testing for a DOT card includes a regular eye test for which candidates must achieve at least 20/40 in each eye, peripheral vision testing, and testing of the ability to distinguish between traffic signals. Results are recorded with or without corrective eyewear, so if drivers routinely wear glasses or contact lenses, they should wear them for the test. • Hearing testing for a DOT physical in Maryland and elsewhere requires that the applicant be able to hear a forced whisper at a distance of five feet. It also requires that candidates have no more than 40 decibels of hearing loss in their better ears. Again, applicants who routinely use a hearing aid are allowed to (and encouraged to) wear the aid during the test.
