Driving at night requires increased caution because:
- Traffic moves faster at night.
- There is a larger volume of traffic at night.
- Drivers cannot see as well at night. ✓
- Accidents occur more frequently at night.
Answer: C. Drivers cannot see as well at night.
Driving at night requires extra caution because you cannot see as far ahead, and glare from oncoming traffic can cut your vision down even more.
Why this is the answer
The handbook opens its night driving section by telling you to drive with extra care after dark, and it gives the reason right there: your ability to see ahead shrinks, and oncoming headlights add glare that makes it worse. The rest of the section follows from that same problem, such as avoiding driving faster than what your lights let you see and not staring into oncoming headlights. Reduced vision is the reason night driving calls for more caution.
Why the other answers are wrong
- A. Traffic moves faster at night. — Nothing in the handbook says traffic moves faster after dark; the night section is about what you can see, not about speed limits changing.
- B. There is a larger volume of traffic at night. — The handbook never claims there is more traffic at night; its concern is that you can't see as far ahead and glare hurts your vision.
- D. Accidents occur more frequently at night. — While the handbook urges extra care at night, it does not state that accidents happen more often then, so this is not the reason it gives.
Remember it
Think of night driving as driving on a shorter leash: your headlights only show you so much, so keep your speed inside what you can actually see.
