Question 927Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND Which signal shall a power-driven vessel sound when making way in fog?
AI Explanation
The correct answer is B) One prolonged blast every two minutes.
According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a power-driven vessel making way in fog must sound one prolonged blast (4-6 seconds) every two minutes. This signal indicates the vessel's presence and the need for other vessels to exercise caution.
The other options are incorrect because: A) one short blast is not the required signal, C) three short blasts is the signal for a vessel not under command, and D) one prolonged and two short blasts is the signal for a vessel towing another vessel.
