Question 944 Rules of the Road
90% to passBOTH INTERNATIONAL & INLAND While underway in fog you hear another vessel sounding two prolonged blasts every two minutes. What does this signal indicate?
A
A vessel is drifting
B
A vessel is towing
C
A vessel is anchored
D
A vessel is making way through the water
AI Explanation
The correct answer is A) A vessel is drifting. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel that is drifting or not under command must sound two prolonged blasts every two minutes to indicate its status. This signal alerts other vessels in the area that the vessel is not under control and may be difficult to avoid. The other options are incorrect because a vessel that is towing would sound three blasts, a vessel at anchor would sound one prolonged blast, and a vessel making way through the water would not sound this particular signal.
