Which statement about drinking alcohol and driving is true?

• A. It has no effect on driving
• B. It improves judgment
• C. It affects judgment and self-control
• D. It only affects reaction time

Answer: (C)

Alcohol affects driving by reducing your ability to judge speed and distance and lowering your self-control, which makes you more likely to take risks. These two mental skills are essential for safe driving: they help you gauge gaps, choose a safe speed, and resist impulsive actions like weaving, tailgating, or braking too late. When judgment or self-control is diminished, you’re more prone to errors that can lead to crashes. While alcohol also slows reaction time and coordination, the statement that best captures its effect is that it undermines judgment and self-control. The other options aren’t true because alcohol does affect driving, it does not improve judgment, and its impact is broader than just reaction time.
