Driving at night requires increased caution because?

Driving at night necessitates heightened caution primarily because a driver cannot see as well in low-light conditions. During nighttime, visibility is significantly reduced compared to daylight, making it more challenging to perceive potential hazards, including pedestrians, cyclists, road signs, and other vehicles. The limited range of headlights further constrains how much of the road ahead is illuminated, which can affect a driver's reaction time to unexpected obstacles. This reduction in visibility increases the likelihood of accidents if drivers do not adjust their driving behavior to accommodate the conditions they are facing at night.

While there may be concerns related to the frequency of accidents or the activity level of animals during the night, or even the confusing effects of streetlighting, these factors are secondary to the fundamental issue of reduced visibility, which necessitates greater caution for safe driving at night.
