What is the requirement for challenging driving tasks that exceed 6 METs?

For challenging driving tasks that exceed 6 METs (Metabolic Equivalent of Task), it is necessary to obtain an evaluation from a cardiologist. The reason for this requirement is based on the understanding that activities involving 6 METs or greater are considered to place significant physiological demands on an individual. It is crucial to ensure that a driver's cardiovascular system is capable of handling such exertion levels, especially for commercial drivers who must maintain high safety standards on the road.

Cardiologists have specialized training in assessing heart function and can evaluate whether an individual has the necessary cardiovascular fitness and stability to safely perform these driving tasks. This helps in preventing potential medical emergencies that could arise from undiagnosed cardiovascular conditions during the demanding activities associated with driving.
