Which of the following is true regarding alcohol consumption and driving?

Alcohol impairs vision, which is a crucial factor in safe driving. When a person consumes alcohol, it can lead to blurred vision, reduced peripheral vision, and difficulties in depth perception. These impairments can significantly affect a driver's ability to see clearly and react to their surroundings, making driving more dangerous. The impairment of vision is one of the key reasons why driving under the influence of alcohol is considered a serious hazard and is illegal in most jurisdictions.

In contrast to the correct answer, the other options highlight common misconceptions. While alcohol may slow reaction times, it does not improve decision-making skills or have no effect on abilities at all. In fact, it negatively affects cognitive functions and overall driving performance. Understanding the impact of alcohol on vision and other driving-related skills is essential for promoting safety on the roads.
