Which statement best describes the effect of alcohol on driving safety?

• A. Alcohol consumption has no effect on driving safety
• B. Alcohol improves reaction time
• C. Alcohol can impair judgment and reaction time, increasing crash risk
• D. Alcohol only affects memory

Answer: (C)

Alcohol slows brain processing and motor skills, so it dulls judgment and slows reaction time. When judgment is impaired, a driver has a harder time assessing hazards, estimating speed and distance, and making safe decisions. Slower reaction time means longer to respond to sudden events, which together increase the chance of a crash. That’s why this statement—alcohol can impair judgment and reaction time, increasing crash risk—best describes its effect on driving safety. Other options aren’t accurate: alcohol does have an effect, it does not improve reaction time, and its impact goes beyond memory, affecting judgment, coordination, attention, and decision-making.
