What distress signals must be carried on a Public Vessel?

• A. Day signals only
• B. Night signals only
• C. Day and Night Distress signals
• D. No distress signals are required

Answer: (C)

Public vessels must be equipped to signal distress in all lighting conditions, so you need both day and night distress signals. Day signals are designed to be conspicuous in daylight, while night signals provide a visible indication in the dark. Relying on only one type could leave you unseen after sunset or in low light, which is unsafe and not acceptable. Carrying both ensures you can signal for help regardless of the time of day.
