CLEET Law Enforcement Driver Practice Test 2026 – Comprehensive Exam Prep

Poor night vision significantly impacts driving performance primarily by reducing a driver's ability to see and react to obstacles and changes in the environment. Night driving typically involves lower visibility conditions that can make it difficult to detect hazards early or differentiate between objects at a distance. This impaired vision can slow down a driver's response to unexpected situations, such as pedestrians or other vehicles that may appear suddenly. Additionally, reduced awareness due to limited sight can lead to difficulties in assessing distances and speeds of oncoming traffic, further compromising overall safety while driving at night.

The other choices suggest benefits that do not align with the realities of poor night vision. Enhancing depth perception or navigating easier in darkness is generally not the case; rather, poor vision leads to challenges in both areas. Improving overall driving performance contradicts the foundational understanding of how limited visibility negatively affects driving abilities.
