Does alcohol impair your driving performance significantly more than driving while drowsy?

The assertion that alcohol impairs driving performance significantly more than drowsiness is often misunderstood. While both alcohol and fatigue negatively impact cognitive functions and motor skills, research has shown that drowsiness can impair driving performance to a level that is comparable to alcohol impairment.

Driving while drowsy can cause slowed reaction times, decreased vigilance, and impaired judgment, similar to the effects of alcohol consumption. In some studies, a driver who is extremely sleepy can exhibit performance levels similar to a driver with a blood alcohol concentration (BAC) of 0.08%, which is the legal limit in many places and is considered intoxicated.

This means that driving under the influence of fatigue may carry risks akin to driving while intoxicated, highlighting that both situations significantly impair driving ability. Hence, the answer indicates that drowsiness is indeed a serious threat to driving safety, similar to alcohol impairment, making the assertion that alcohol impairs more significantly than drowsiness inaccurate in this context.
