Which factor is NOT considered when certifying drivers with coronary heart disease?

When certifying drivers with coronary heart disease, the age of the driver is not a direct factor taken into account as it pertains to the evaluation of their medical fitness. The focus of the certification process is primarily on the clinical aspects of their condition and its management rather than demographic information such as age.

The testing primarily examines the driver's medical history, including cardiovascular procedures, current fitness levels, and how well their symptoms are managed and controlled. These elements provide insights into the individual's current health status and their ability to perform safely while operating a commercial vehicle. By prioritizing specific health metrics over age, the certification process aims to ensure that only those drivers who meet established health criteria and can demonstrate proper management of their condition are deemed fit for driving, regardless of their age.
