What impact does alcohol consumption have on driving performance?

Alcohol consumption significantly affects driving performance, primarily by slowing down reaction times and impairing judgment. When an individual consumes alcohol, the central nervous system is affected, leading to decreased coordination, slower processing of information, and an overall reduction in cognitive abilities. This means that a driver under the influence may not respond as quickly to sudden changes in traffic conditions, such as a pedestrian crossing the street or another vehicle stopping unexpectedly.

Additionally, alcohol affects decision-making skills, which can lead to poor choices on the road, such as speeding, ignoring traffic signals, or misjudging distances. This impairment increases the likelihood of accidents and dangerous situations, making it crucial for drivers to avoid alcohol consumption if they plan to drive.

In contrast, the other options suggest that alcohol has positive effects or no effects on driving, which contradicts substantial research and real-world evidence demonstrating the dangers of driving under the influence.
