Question 445 Rules of the Road

The correct answer is D) Maintain course and speed. This is the correct answer because according to the International Regulations for Preventing Collisions at Sea (COLREGS), when two power-driven vessels are crossing, the vessel that has the other on its own starboard side (Vessel "B" in this case) is the stand-on vessel and must maintain its course and speed. Vessel "A" is the give-way vessel and must take action to avoid a collision by altering course to starboard. The other options are incorrect because they would go against the COLREGS rules for a crossing situation. Sounding a signal or altering course or speed is the responsibility of the give-way vessel, not the stand-on vessel.
