How can even a low BAC level affect a person's driving capabilities?

A low Blood Alcohol Concentration (BAC) level can significantly impair cognitive functions, which includes a range of mental processes such as attention, decision-making, and the ability to process information. Even small amounts of alcohol can disrupt the brain’s normal operations, affecting how a person perceives their environment, reacts to stimuli, and makes decisions.

This impairment can lead to slower reaction times and difficulties in multitasking, both of which are crucial for safe driving. As cognitive functions decline, a driver may misjudge distances, fail to respond appropriately to road conditions, or even lack the ability to focus on the task of driving itself. Therefore, understanding the impact of low BAC levels on cognitive functions is critical for ensuring safety on the road.
