When must navigation lights be used?

• A. From sunset to sunrise and during periods of restricted visibility
• B. Only during storms
• C. Only at noon
• D. Only when anchored

Answer: (C)

Navigation lights are used whenever visibility is limited or it’s dark so other boaters can see your vessel and judge its position and direction. From sunset to sunrise you must display the proper lights, and you also need them during periods of restricted visibility such as fog, rain, or haze. Daylight hours don’t require navigation lights, so the idea of using them only at noon isn’t correct. They aren’t limited to storms, and they aren’t required only when anchored. In practice, a vessel underway at night or in reduced visibility uses the navigation lights to communicate its presence and status.
