Question 254Rules of the Road90% to pass

BOTH INTERNATIONAL & INLAND You are underway in reduced visibility. You hear the fog signal of another vessel about 20° on your starboard bow. Risk of collision may exist. Which action should you take?

AI Explanation
The correct answer is D) Reduce your speed to bare steerageway. When you hear the fog signal of another vessel in reduced visibility, the appropriate action is to reduce your speed to the minimum required to maintain steerage. This allows you to better assess the risk of collision and take appropriate action, as required by the International Regulations for Preventing Collisions at Sea (COLREGS). The other options are incorrect because altering course (A or C) could put you on a collision course, and slowing to let the other vessel pass ahead (B) may not allow you to take effective action if the risk of collision increases.
