Just like alcohol and other drugs, drowsiness can:
- Help you to be a better driver.
- Make you feel better.
- Impair your judgment. ✓
Answer: C. Impair your judgment.
Drowsiness, like alcohol and other drugs, can impair your judgment.
Why this is the answer
The handbook's chapter on drowsy and fatigued driving says plainly that a tired driver reacts more slowly, is less aware, and has impaired judgment. It also compares drowsiness to drugs and alcohol, noting that drowsiness can contribute to a traffic crash. That comparison is exactly what the question asks about, so the choice about impaired judgment fits the manual's wording.
Why the other answers are wrong
- A. Help you to be a better driver. — The manual says driving and sleep do not mix and that fatigue is dangerous behind the wheel, so drowsiness never makes you a better driver.
- B. Make you feel better. — Nothing in the handbook suggests drowsiness makes you feel better; it lists slower reactions, poor awareness and impaired judgment instead.
Remember it
Think of tiredness as a drug you cannot pour out: it dulls your reactions, your awareness and your judgment.
