What is the effect of alcohol consumption on driving ability?

Alcohol consumption significantly impairs driving ability by increasing the risk of accidents. This occurs because alcohol affects various cognitive and motor functions necessary for safe driving. It slows reaction times, impairs judgment, and diminishes coordination, all of which can lead to poor decision-making on the road and an inability to respond quickly to sudden changes or emergencies.

When a driver is under the influence of alcohol, their ability to assess distances, judge speed, and process information from the environment deteriorates. This heightened impairment correlates directly with an increased likelihood of involvement in a crash. According to statistics and studies, drivers with alcohol in their system are far more likely to be involved in traffic accidents compared to sober drivers.

The other options do not accurately reflect the impacts of alcohol on driving. Alcohol does not improve any aspect of driving performance, nor does it enhance focus or have no effect on driving—it consistently detracts from the ability to operate a vehicle safely.
