Question 49 TV02 - Towing Vessels - Great Lakes and Inland

The Correct Answer is C **Why option C ("The vessel is in distress") is correct:** According to both the International Regulations for Preventing Collisions at Sea (COLREGs) Annex IV and Inland Navigation Rules, a gun or other explosive signal fired at intervals of about one minute is a recognized and prescribed distress signal. This signal is designed to attract immediate attention and indicate that a vessel is facing grave and imminent danger and requires assistance. **Why other options are incorrect:** * **A) The gun is being used to sound passing signals:** Passing signals (such as one short blast, two short blasts, etc.) are sounded on the vessel's whistle or horn, not typically by firing a gun at one-minute intervals. A gun fired at regular intervals is specifically reserved for distress. * **B) All vessels are to clear the area:** While the presence of a distress situation may necessitate other vessels maneuvering (especially if they are responding to assist), this signal does not specifically instruct *all* vessels to clear the area. Its primary purpose is to declare distress and solicit help. * **D) All is clear and it is safe to pass:** This signal indicates the exact opposite. A vessel firing a distress signal is in danger, meaning the immediate area may not be safe, and assistance, rather than simply passing, is required.
