What is one effect of driving at night that drivers should be cautious of?

Answer: B — Reduced visibility and increased chance of fatigue

Driving at night significantly impacts visibility, as darkness can hinder a driver’s ability to see clearly, particularly on poorly lit roads. This reduced visibility means that objects, pedestrians, or other vehicles may be harder to spot in time to react safely. Additionally, the human body inherently produces more melatonin in the evening, which can lead to increased drowsiness and fatigue, further complicating driving conditions. These factors combined elevate the risk of accidents at night, making it crucial for drivers to be mindful of their limitations and the challenges posed by nighttime driving. While some might think that there is less traffic at night, the potential for encountering impaired drivers or obstacles is heightened, making awareness and caution even more essential.
