If you are traveling in a primary channel and encounter a junction buoy (with the green band on top) when proceeding in an upstream direction what must you do?

When traveling upstream and encountering a junction buoy with a green band on top, you should keep the buoy on your right side. This indicates that it marks the entrance to a channel, directing you to the preferred channel on your right. Make sure to navigate according to the buoy's guidance to ensure safe passage.
