This measurement consists of two numbers: the systolic pressure (top number), representing the pressure when the heart beats, and the diastolic pressure (bottom number), representing the pressure when the heart rests between beats.

According to DOT guidelines, drivers with a blood pressure reading of 140/90 or below may be medically certified to drive for a two-year period. Those with a blood pressure reading between 140-159 systolic and/or 90-99 diastolic can be certified for one year, and will need annual recertifications.

Readings of 160-179 systolic and/or 100-109 diastolic lead to a three-month certification. However, drivers with a blood pressure reading of 180/110 or higher are disqualified until their blood pressure is controlled and falls below 140/90.

  • Cardiovascular Health: Heart health is critical for commercial drivers. Any history or symptoms of cardiovascular disease, such as chest pain or shortness of breath, must be investigated. In some cases, additional testing may be required to evaluate cardiac health.
  • Respiratory System: Respiratory issues can be a safety concern for drivers. Conditions such as chronic obstructive pulmonary disease (COPD), sleep apnea, and other respiratory disorders will be evaluated.
  • Neurological Function: The physical includes an evaluation of drivers' mental and emotional health, as well as a basic neurological exam to assess coordination and reflexes.
  • Musculoskeletal Examination: A physical examination will assess a driver's ability to perform physical tasks necessary for driving a commercial vehicle, such as bending, stooping, reaching, and the ability to maintain a certain posture for extended periods.
  • Medical History: A comprehensive medical history is part of the examination. It includes past and current illnesses, surgeries, and medications.
