Restricted visibility refers to which of the following?

• A. Only fog
• B. Heavy rain
• C. Visibility is unrestricted
• D. Any condition where visibility is restricted

Answer: (D)

Restricted visibility means any condition in which your ability to see other vessels, hazards, or navigation aids is limited. It isn’t tied to one weather event; fog is common, but heavy rain, snow, smoke, dust, glare, or darkness all fall under restricted visibility as well. That broad definition is why this option is the best: it correctly covers all situations where visibility is limited, not just a single cause. The other choices are too narrow or the opposite of what’s meant. When visibility is restricted, take prudent actions such as reducing speed to a safe level, using sound signals as required, and employing available navigation aids to maintain safety.
