Even when not legally drunk, alcohol can impair driving by affecting which aspects?

• A. Visual acuity
• B. Judgment
• C. Coordination
• D. All of the above

Answer: (D)

Alcohol affects driving in several ways, even before you reach the legal limit. It can dull visual sharpness, making it harder to see details, judge distances, and respond to changing traffic conditions. It also impairs judgment, so you’re more likely to misjudge speeds, gaps, and risks. Coordination takes a hit too, slowing your reaction time and making precise steering, braking, and throttle control more difficult. Because visual acuity, judgment, and coordination can all be affected, the safest conclusion is that all of these aspects can be impaired, which is why the best choice is all of the above.
