Question 98 Rules of the Road

The correct answer is A) Your speed must be reduced to bare steerageway. This is the correct answer because under both the International and Inland Rules, when in a situation of reduced visibility due to fog, the vessel's speed must be reduced to the minimum required to maintain safe navigation and control of the vessel. Reducing speed to bare steerageway allows the vessel to be maneuvered more effectively to avoid a collision. The other options are incorrect because: B) Keeping the radar on a short-range scale is recommended but not required, C) A lookout is always required regardless of radar use, and D) Fog signals must be sounded at all times when underway in reduced visibility, not just when another vessel is detected by radar.
