How does alcohol affect a driver's ability?

Alcohol significantly impairs a driver's abilities in several critical areas, making it unsafe to operate a vehicle. Specifically, alcohol affects judgment by impairing the ability to assess risks and make sound decisions while driving. This can lead drivers to take unnecessary risks, such as speeding or making poor lane changes.

Coordination is also adversely impacted by alcohol, which can lead to difficulties in performing the precise movements required for safe driving, such as steering, accelerating, and braking. Additionally, alcohol slows down reaction times, meaning that a driver may not respond quickly enough to sudden changes on the road, such as another vehicle stopping unexpectedly or a pedestrian crossing.

Understanding these effects is crucial for promoting safe driving practices and recognizing the dangers of driving under the influence. The other options do not align with how alcohol actually influences driving skills and safety.
