252. As your vessel is heading southward along the east coast of the United States, you encounter a buoy showing a red flashing light. How should you pass this buoy?

As the U.S. utilizes the IALA Region B buoyage system, a red flashing buoy indicates the starboard side of the channel when proceeding in the conventional southbound direction along the U.S. East Coast; therefore, it should be left to starboard.
