Question 43 MODU03 - Ballast Control Operator

The Correct Answer is C ### Why Option C ("A distress signal") is correct: The action described—raising and lowering outstretched arms slowly and repeatedly to each side—is the universally recognized daylight visual distress signal, as defined in the International Regulations for Preventing Collisions at Sea (COLREGs), Annex IV, section 1(j). This signal indicates that the vessel or person is in serious and imminent danger and requires assistance. ### Why the other options are incorrect: **A) All is clear, it is safe to pass:** This signal is generally not conveyed by arm movements in maritime signaling. Clearance or safety signals typically involve specific flag signals (e.g., Code Flag L for "You should stop instantly") or specialized lights/sounds, not the specific up-and-down arm motion described. **B) All is clear, it is safe to approach:** Similar to A, this specific motion does not indicate clearance or safety. A common non-distress signal using arms is waving slowly from side to side or holding the arms out horizontally, which might indicate "stop" or "wait," but not the specific distress signal described. **D) Danger, stay away:** While the signal indicates danger, the primary function of a distress signal is to request immediate assistance, not merely to warn others to stay away. The recognized signal for danger or warning (like the raising and lowering of outstretched arms) is specifically categorized as a distress signal under international maritime law, meaning the signaler needs help.
