Question 254 Rules of the Road

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.
