Question 493Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND While underway in fog you hear the rapid ringing of a bell. What does this signal indicate?
AI Explanation
The correct answer is D) A vessel at anchor.
According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel at anchor is required to ring its bell rapidly for about 5 seconds at intervals of not more than 1 minute. This signal indicates that the vessel is at anchor and not underway. The rapid ringing of a bell does not apply to a vessel drifting, backing down, or a sailboat underway, which is why the other options are incorrect.
