How does alcohol consumption affect coordination while driving?

Alcohol consumption has a profound effect on various cognitive and motor functions, particularly coordination, which is essential for safe driving. When consumed, alcohol impairs the brain's ability to communicate effectively with the nervous system, leading to decreased motor skills and slowed reaction times. This impairment deteriorates hand-eye coordination, balance, and overall motor control, making it difficult for a driver to operate a vehicle safely.

The judgment becomes compromised too, causing individuals to misjudge distances and vehicle speeds. As a result, a driver under the influence may find it challenging to execute maneuvers such as steering, braking, or accelerating correctly, which can lead to accidents. The relationship between alcohol and coordination is well-documented, emphasizing that even moderate consumption can significantly impact driving performance. This is why the correct answer identifies that alcohol consumption decreases coordination while driving.
