Which statement best describes the impact of alcohol on driving ability?

• A. Alcohol impairs coordination, judgment, and reaction time, increasing crash risk.
• B. Alcohol improves reaction time.
• C. Alcohol has no effect on driving.
• D. Alcohol only affects vision but not motor skills.

Answer: (A)

Alcohol disrupts the abilities you rely on most when behind the wheel: coordination, judgment, and reaction time. When you drink, fine motor skills needed to steer and stay in your lane become shakier, your ability to judge distances and speeds worsens, and your reflexes slow down, making it harder to respond to hazards quickly. All of this adds up to a higher chance of crashes. The idea that alcohol would improve reaction time or that it has no effect on driving isn’t accurate, and alcohol also affects more than just vision—motor skills and decision-making are impaired too. So the best description is that alcohol impairs these driving-critical abilities and increases crash risk.
