Which is NOT a psychological effect of alcohol that impairs driving?

• A. Alcohol lowers your body temperature
• B. It slows reaction time
• C. It reduces coordination
• D. It impairs judgment

Answer: (A)

The key idea is how alcohol affects driving through mental and motor impairments. Alcohol slows the brain’s processing, so judgment becomes poorer, reaction time increases, and coordination suffers. These are psychological or cognitive-motor effects that directly harm driving ability. Lowering body temperature, on the other hand, is a physiological change, not a mental or cognitive impairment that would impair driving in the same way. So describing a temperature drop isn’t naming a psychological effect that impairs driving, which is why that option is the correct choice.
