What Changes Occur in Nighttime Visibility Distance?

[DeNicole]

Nighttime drivers have significantly poorer visibility of objects compared to daytime, with reduced visibility distance. Here are the relevant details: 1. Reasons for reduced visibility distance: At night, while driving on the road, due to the effect of headlights, drivers see bright objects against a dark background, making these objects appear larger. However, the eyes still judge distance based on the perception that closer objects appear larger, leading to a reduced visibility distance. 2. Field of vision: Motor vehicle drivers can only clearly see objects illuminated by the headlights. The high beams of a car typically illuminate up to about 150 meters, while low beams cover around 30 meters, generally not extending beyond the road surface. Objects beyond this distance and range cannot be seen clearly.
