Which of the following would NOT disqualify an applicant from receiving a medical examiner certificate?

Controlled high blood pressure would not disqualify an applicant from receiving a medical examiner certificate because it can typically be managed effectively with medication and lifestyle changes. When an individual's blood pressure is consistently within the acceptable range and under control, they can usually meet the medical standards required for commercial driving.

In contrast, severe visual impairment, active epilepsy, and significant cardiovascular disease are conditions that present substantial risks while operating a commercial vehicle. Severe visual impairment could hinder a driver's ability to see adequately, which is critical for safety on the road. Active epilepsy poses a risk of seizures, which can occur unpredictably and impair driving ability. Cardiovascular disease, depending on its severity and the specific symptoms present, could severely affect an individual's physical capabilities and response times while driving, making it a disqualifying condition under certain circumstances.
