What is a degraded visual environment?

• A. Cloudy day
• B. Visual environment where a state of reduced visibility exists
• C. No hazard
• D. Clear night

Answer: (B)

A degraded visual environment is any situation where visibility is reduced and visual cues are compromised, making it harder to see and judge distances, height, and motion. The option that states “a visual environment where a state of reduced visibility exists” directly describes this condition, which is why it is the best choice. A cloudy day describes weather, but it doesn’t specify the level of visibility reduction, which can vary and isn’t a precise definition of DVE. A no hazard scenario is incorrect because a degraded visual environment inherently increases risk by limiting what the operator can see. A clear night is not inherently degraded; while lighting can influence visibility, the term DVE refers to a reduced-visibility state, not simply the time of day.
