Question 897Rules of the Road90% to pass

BOTH INTERNATIONAL & INLAND You are approaching a bend in a river where, due to the bank, you cannot see around the other side. A vessel on the other side of the bend sounds one prolonged blast. In response, which signal are you required to sound?

AI Explanation
The correct answer is B) Sound a prolonged blast. The reasoning for this is that when approaching a bend in a river where you cannot see the other side, and another vessel on the other side sounds a prolonged blast, the proper response is to sound a prolonged blast yourself. This alerts the other vessel of your presence and intention to navigate the bend. The regulations require this action to ensure safe passage around the bend when visibility is limited. The other options are incorrect because: A) Sounding the danger signal is not the appropriate response in this situation. C) Sounding passing signals is not necessary until you have visual contact with the other vessel. D) You should not wait to sound any signal until you sight the other vessel, as this could lead to a collision.
