What is the leading etiology for sudden driver incapacitation?

Coronary Heart Disease is identified as the leading cause of sudden driver incapacitation primarily due to the fact that it can lead to acute medical emergencies, such as heart attacks, which may strike suddenly and without warning. This condition significantly impairs a person’s cardiovascular system, making it more susceptible to life-threatening events. Given the critical nature of driving, the sudden onset of incapacitation caused by a heart condition can result in severe accidents, as it affects a driver’s ability to maintain control of the vehicle.

In comparison, while diabetes, hypertension, and obesity are all serious health conditions that can impact driving, they typically do not present the immediate and acute risk of sudden incapacitation in the same way that coronary heart disease does. Diabetes can lead to neuropathy or hypoglycemic events, hypertension may not cause immediate incapacitation unless it leads to a severe incident (like a stroke), and obesity is a risk factor for heart disease itself but does not directly cause sudden incapacitation. Thus, in the context of sudden incapacitation while driving, coronary heart disease stands out as the primary risk factor.
