Under the Rules, the lights prescribed shall be exhibited in which condition?

• A. Only at night
• B. All times
• C. From sunrise to sunset in restricted visibility
• D. During daylight only

Answer: (C)

When visibility is restricted, ships must display the prescribed navigation lights to help other vessels see them and determine their presence and course. This isn’t limited to nighttime; it can apply during daylight if conditions like fog, rain, or mist reduce visibility. So lights must be shown from sunrise to sunset whenever visibility is restricted, not only at night or all the time. That’s why the correct choice is the one that specifies showing lights in restricted visibility during daylight hours.
