Night driving can be more difficult than driving during the day because:

1. Cars overheat more quickly at night.
2. Visibility is reduced in the dark. ✓
3. It is more likely to be raining at night.
4. You are more likely to encounter a motorcycle at night.

Answer: B. Visibility is reduced in the dark.

Night driving is more difficult mainly because visibility is reduced in the dark.

Why this is the answer

The Texas handbook says driving at night is much more dangerous than driving during the day, and it notes that many people do not see as well at night. That directly points to reduced visibility as the reason night driving is harder. The same section advises taking trips during daylight hours and not driving when tired, but the key reason given for night driving being harder is that people see less well after dark.

Why the other answers are wrong

• A. Cars overheat more quickly at night. — The passages do not say cars overheat more quickly at night.
• C. It is more likely to be raining at night. — The passages do not say rain is more likely at night.
• D. You are more likely to encounter a motorcycle at night. — The passages do not say motorcycles are more likely to be encountered at night.

Remember it

Darkness means less to see; that is the main reason night driving is harder.
