Driving at night is particularly dangerous for commercial drivers primarily due to the combination of fatigue and reduced visibility that can significantly impair judgment. Nighttime driving presents unique challenges compared to daytime, as visibility is greatly diminished. This can make it harder to see other vehicles, pedestrians, and potential hazards on the road.

In addition, fatigue can be a significant factor for commercial drivers, especially those who have long hours on the road. The combination of tiredness, which slows reaction times and decreases attention, with limited lighting conditions can lead to increased risks of accidents.

While heavy traffic, icy roads, or the absence of streetlights also present dangers, the specific and compounded issues of fatigue and poor visibility at night create a particularly hazardous environment for commercial drivers, making it vital for them to remain alert, well-rested, and cautious while driving after dark.
