What color is used for buoys that are meant to be passed on the right side?

The correct color for buoys that are meant to be passed on the right side is red. This color is part of the navigational aids established by the United States Coast Guard as part of the system used to mark channels for safe navigation. According to the lateral system of buoyage, red buoys indicate the right side of the channel when you are heading upstream, which is generally toward the location of the water source or point of origin of the river. This system helps boaters navigate effectively and is crucial for ensuring safe passage.

In contrast, green buoys, which are not the focus here, indicate the left side of the channel when heading upstream. Yellow buoys often signify special use areas or no-wake zones, and blue buoys are typically associated with mooring or anchoring locations for vessels. Understanding these color codes is essential for safe boating practices, as they provide vital information about navigation routes and safety.
