It is mandated by federal guidelines that all commercial drivers pass the DOT physical exam. The goal of this test is to check whether an applicant is physically capable of driving safely now and in the near future. Successfully passing the exam usually means you have 24 month before you need to do it again, although in some instances this period might be shortened in case that serious health problems could arise in the future.
