What is the effect of alcohol on motor skills essential for driving?

Alcohol significantly impairs motor coordination that is critical for driving tasks such as steering and braking. When consumed, alcohol affects the central nervous system, leading to slowed reflexes, reduced coordination, and impaired judgment. This impairment can make it difficult to respond quickly to changes in road conditions, control the vehicle effectively, and make sound decisions while driving.

The correct choice highlights how these essential motor skills, which require precise control and timing, are negatively affected when a driver is under the influence of alcohol. Understanding this impact is crucial for promoting safe driving behaviors and assessing the risks associated with alcohol consumption before operating a vehicle.
