Which of the following does alcohol affect?
- Recovery from headlight glare
- Reaction time
- Judgment of distances
- All of these choices ✓
Answer: D. All of these choices
Alcohol affects all of these: recovery from headlight glare, reaction time, and judgment of distances.
Why this is the answer
The handbook's alcohol chapter says drinking slows your reaction time, weakens your ability to see clearly, and changes how you judge speed and distance. It adds that alcohol also lowers your ability to recover from the glare of oncoming headlights. Since each skill named in the choices appears in that list, the choice covering all of them is correct. The manual notes these effects can start with the first drink, before you look or feel drunk.
Why the other answers are wrong
- A. Recovery from headlight glare — Recovery from headlight glare is one effect of alcohol named in the manual, but picking it alone leaves out the other effects listed.
- B. Reaction time — Slower reaction time is only one of the effects the manual describes, so this choice is incomplete.
- C. Judgment of distances — Poorer judgment of speed and distances is just one item on the manual's list, not the whole answer.
Remember it
Alcohol touches every driving skill at once, so when a question lists several skills you know it harms, look for the choice that covers them all.
