What does alcohol do to your driving skills and judgement?
- It helps driving skills but harms your judgement.
- It harms both driving skills and judgement. ✓
- It has no effect on either driving skills or judgement.
- It has no effect on judgement but it harms driving skills.
Answer: B. It harms both driving skills and judgement.
Alcohol harms both your driving skills and your judgement.
Why this is the answer
The handbook's chapter on alcohol says it delays your reaction time, cuts down how clearly you see, and changes how you judge speed and distance. It also says the skills you need to drive safely are made weaker, and that drinking often makes people less inhibited and more likely to take chances. That covers both sides of the question: the physical skills and the decision-making. The manual adds that these effects can start with the first drink, before you look or feel intoxicated.
Why the other answers are wrong
- A. It helps driving skills but harms your judgement. — Alcohol does not improve anything you need behind the wheel; the manual says the skills for safe driving are made weaker, and your judgement of speed and distance is changed for the worse.
- C. It has no effect on either driving skills or judgement. — The manual lists clear effects on reaction time, vision, and judgement of speed and distance, so saying alcohol has no effect contradicts it.
- D. It has no effect on judgement but it harms driving skills. — Judgement is not spared; the manual says alcohol changes your judgement of speed and distances and makes you more prone to take chances.
Remember it
Think of alcohol as a double loser: it dulls the hands and eyes and muddles the decisions at the same time.
