DOT physical exams assess your ability to safely operate a commercial vehicle. If you pass a DOT physical examination, you will be given a Medical Examination Report and a Medical Examiner's Certificate. The DOT physical will cover:
Medical history: You will need to provide medical records that display your medical history. The examiner will also ask questions about the medication you take, surgeries you've had, and substances you may use (like drugs, alcohol, and tobacco).
Physical examination: Your examiner will perform a full physical evaluation to assess your eyesight, hearing, and blood pressure. The doctor will determine whether you have any underlying conditions.
Urinalysis: You will be asked to take a urine test to screen for health conditions such as diabetes.
Most health conditions will not keep you from passing a DOT physical for your CDL. There are, however, a few conditions that may disqualify you, including:
High blood pressure
Some cases of sleep apnea
Poor vision that cannot be corrected
Deafness that cannot be corrected with hearing aids
Heart or lung disease
If you can manage some of the conditions listed above, you may still be able to pass a DOT physical. The medical examiner will ask questions about how you manage such conditions, and how they affect your daily life.
