Question 189 Rules of the Road

The correct answer is A) have her engines ready for immediate maneuver. This is the correct answer because the International Regulations for Preventing Collisions at Sea (COLREGS) Rule 19 states that in restricted visibility, a power-driven vessel shall have her engines ready for immediate maneuver. This allows the vessel to take prompt action to avoid a collision if necessary. The other options are incorrect because B) operating at a slow speed is recommended but not required, C) sounding fog signals is required but not the only action, and D) stopping engines when not at risk of collision is not required by the COLREGS.
