Night driving can be more difficult than driving during the day because:
- Cars overheat more quickly at night.
- Visibility is reduced in the dark. ✓
- It is more likely to be raining at night.
- You are more likely to encounter a motorcycle at night.
Answer: B. Visibility is reduced in the dark.
Night driving is harder mainly because visibility is reduced in the dark, so you can't see as far or as clearly as you can in daylight.
Why this is the answer
The handbook's low visibility section is built around one idea: anything that cuts down what you can see makes driving harder. It lists smoke, fog and heavy rain as things that affect your ability to see, and it tells you to turn on headlights, use low beams so glare doesn't bounce back at you, and use wipers and defrosters to get the clearest view possible. Darkness is the same kind of problem, so the answer points to reduced visibility as the reason night driving is more difficult.
Why the other answers are wrong
- A. Cars overheat more quickly at night. — The handbook passages say nothing about engines getting hotter at night; they deal with what you can see, not vehicle temperature.
- C. It is more likely to be raining at night. — Rain is mentioned only as one example of something that lowers visibility, and the passages never claim rain is more likely after dark.
- D. You are more likely to encounter a motorcycle at night. — Motorcycles are not mentioned in these passages, so nothing there says you meet more of them at night.
Remember it
When a question asks why night driving is harder, think about what your eyes lose after sunset, not about the weather or the traffic mix.
