What does a higher BAC level indicate about a driver’s ability?

A higher Blood Alcohol Concentration (BAC) level indicates a decreased ability in various aspects of driving performance, most notably coordination. As a person's BAC increases, their motor skills become impaired, leading to difficulty in controlling the vehicle, maintaining balance, and performing complex tasks necessary for safe driving.

This impairment occurs because alcohol affects the central nervous system, disrupting communication between the brain and the body. As a result, drivers may struggle with steering, braking, and responding quickly to changing road conditions. The higher the BAC, the more pronounced these impairments become, ultimately increasing the risk of accidents.

The other choices, while they might describe positive attributes, do not apply at higher levels of BAC, as alcohol consistently degrades a person's cognitive and physical abilities rather than enhancing them. Thus, recognizing that a higher BAC level correlates with decreased coordination is crucial for understanding the risks associated with impaired driving.
