The earliest driving skill affected by alcohol is

• A. Vision
• B. Judgment and decision making
• C. Reaction time
• D. Balance

Answer: (B)

Alcohol first hits the brain areas that control judgment and decision making. When someone drinks, these higher-level functions—risk assessment, impulse control, and the ability to weigh options—are depressed before basic motor skills or sensory abilities are noticeably affected. In driving, this shows up as poorer decisions: misjudging gaps, speeds, or distances, and taking unnecessary risks. That’s why judgment and decision making is the earliest skill impaired. As intoxication deepens, other skills such as reaction time, balance, and vision become impaired, but the initial and most critical change is in how a person thinks through driving decisions.
