Question 949 Rules of the Road
90% to passBOTH INTERNATIONAL & INLAND You are underway in fog and you hear three distinct bell strokes followed by five seconds of rapid bell ringing followed by three distinct bell strokes. What does this signal indicate?
The correct answer is A) A vessel aground. The signal you described, consisting of three distinct bell strokes followed by five seconds of rapid bell ringing and then three more distinct bell strokes, indicates that a vessel is aground. This signal is specified in the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, which are the governing regulations for both international and inland waterways in the United States. The other options are incorrect because they do not match the specific signal pattern described in the question. A vessel in distress would use a different sound signal, a vessel at anchor would use a different pattern, and a vessel engaged in underwater construction would not use this particular sound signal.
