What are the effects of alcohol consumption on motor skills?

Alcohol consumption has a well-documented impact on motor skills, primarily leading to impaired judgment and decreased coordination. When alcohol is consumed, it affects the central nervous system, which can slow down brain function and disrupt communication between the brain and the body. This impairment can lead to slower reaction times, difficulties in hand-eye coordination, balance issues, and poor decision-making abilities.

The correct answer highlights two significant effects: impaired judgment, meaning that a person may make poor choices while under the influence, and decreased coordination, which affects the ability to perform tasks requiring physical skills. This impairment increases the risk of accidents, especially when driving or operating heavy machinery.

In contrast, other choices suggest opposite effects, such as improved reaction time, enhanced coordination, or increased alertness, which do not align with research and evidence regarding the effects of alcohol on the body. It is crucial for drivers to be aware of these impairments to understand the dangers associated with alcohol consumption.
