What is the effect of driving under the influence of alcohol?

Driving under the influence of alcohol significantly impairs various cognitive and psychomotor abilities, including the ability to judge distances accurately. Alcohol affects the brain's processing speed and functionality, leading to challenges in visual perception and spatial awareness. This can result in misjudgments about how far away other vehicles, pedestrians, or obstacles are while driving. Individuals may underestimate or overestimate distances, increasing the risk of accidents. While the other options address potential effects that alcohol may have, such as increased reaction time and impaired decision-making, they do not correctly reflect the primary issue of distance judgment that arises from intoxication.
