What does a yellow buoy signify?

A yellow buoy signifies a caution area, which may indicate various situations such as the presence of a swimming zone or a navigational hazard. This type of buoy is designed to alert boaters and swimmers to exercise caution in that area. It serves as a warning for potential hazards that could impact safety.

Typically, yellow buoys are used to draw attention to conditions that require extra vigilance, such as shallow waters, areas where swimmers are present, or other situations that could pose risks to navigation. Being aware of a yellow buoy helps boaters maintain safe practices and avoid accidents in potentially dangerous zones.

In contrast to the other options, restrictions on sailing or fishing and guaranteed clear passage are denoted using different colors or symbols on buoys, while yellow specifically points towards caution and awareness.
