What effects does alcohol impairment have on driving?

• A. It slows reaction time, diminishes coordination, and impairs judgment
• B. It improves reaction time
• C. It has no effect on driving
• D. It only affects driving at night

Answer: (A)

Alcohol dulls the central nervous system, so driving performance suffers in three key areas: reaction time, coordination, and judgment. When intoxicated, a driver processes information more slowly, reacts to hazards later, struggles to steer smoothly or brake promptly, and makes poorer judgments about speed, distance, and risk. This combination greatly increases crash risk in everyday driving, not just at night. The other statements aren’t accurate: alcohol does not improve reaction time, it does have a significant effect on driving, and its impairment isn’t limited to nighttime driving.
