After drinking an alcoholic beverage, which of the following is the first driving-related ability to be affected?
-
A.
Your vision and depth perception of moving vehicles.
-
B.
Your ability to steer and control the vehicle smoothly.
-
C.
Your judgment about risk and safety. Correct
-
D.
Your reaction time and reflexes at the wheel.
The answer is "Your judgment about risk and safety."
The manual states judgment is the first thing affected after drinking an alcoholic beverage. Reaction time, vision, and vehicle control come next in the same paragraph, not first. Choice D pulls drivers who picture alcohol's headline effect as slowed hands and delayed braking, reaching for the outside symptom of a drunk driver before the mental change the manual puts ahead of it.
The traps in the wrong answers
A. Your vision and depth perception of moving vehicles.
The manual does list reduced ability to see clearly and to judge distance, but only after naming judgment as the first ability affected. This answer trusts the visible signs of a drunk driver (glassy eyes, blurred vision) over the mental change the manual puts before any physical symptom.
B. Your ability to steer and control the vehicle smoothly.
The manual lists trouble controlling the vehicle among alcohol's effects, but only after naming judgment as the first ability impaired. This answer assumes the earliest sign of impairment is what a passenger or officer would spot from outside (swerving, sloppy lane keeping) rather than the mental change that precedes it.
D. Your reaction time and reflexes at the wheel.
The manual names judgment as the first ability impaired; slowed reaction time is listed in the following sentence, not first. This answer follows the pop-culture image of drunk driving as jerky hands and delayed braking, which drivers assume must be alcohol's opening effect.
