The Department of Transportation (DOT) requires all applicants to complete a comprehensive physical exam in order to qualify for and obtain a Commercial Driver’s License (CDL). This exam ensures that you are healthy and physically fit enough to operate a commercial vehicle without risk of injury to yourself or others.
The examiner will review your health history and ask you to list the medications you take on a regular basis. During your DOT physical, the examiner will check your as well as performing a neurological exam and hernia check.
A CDL or DOT Physical is a test to assess general health as well as mental and emotional fitness for the demands of professional driving.
A commercial driver, which includes CDL and non-CDL drivers alike, must be medically certified at least once every 24 months.
The requirement to pass includes adequate vision, color distinction, blood pressure, hearing, cardiovascular health, medication review and more.
The two are the same process from a physical perspective as the purposes are similar. The difference being that a Commercial Drivers License is a wide range of vehicles while DOT is specific to larger commercial vehicles.
