What is the primary risk of driving at night?

Driving at night presents a primary risk due to decreased visibility and impaired judgment caused by darkness. In low-light conditions, drivers cannot see as well as during the daytime, which can lead to difficulties in detecting obstacles, assessing distances, and perceiving the speed of oncoming vehicles. The lack of natural light also makes it harder to notice changes in road conditions, pedestrians, or animals that might suddenly appear.

Additionally, human perception is inherently more affected by limited illumination; therefore, a driver's ability to make quick and accurate decisions diminishes as night falls. These factors significantly increase the chances of accidents, making it essential for drivers to be aware of heightened risks and to take extra precautions when driving after dark.
