How does alcohol affect reaction time while driving?

Alcohol significantly slows down reaction time while driving. This impairment occurs because alcohol affects the brain's ability to process information quickly and accurately. When a driver consumes alcohol, it impedes cognitive functions such as attention, decision-making, and motor skills. As a result, the driver may take longer to respond to critical situations on the road, such as sudden stops, pedestrians crossing, or changes in traffic signals.

The slowing of reaction time can lead to a higher risk of accidents, as individuals may not be able to react swiftly enough to avoid dangerous scenarios. This is a crucial concept to understand because safe driving relies heavily on timely responses to dynamic road conditions and other drivers' actions.
