What does a flashing yellow light typically signify?

A flashing yellow light serves to indicate a special caution area in navigable waters. This type of signal is used to alert mariners to exercise caution due to potential hazards or changing conditions within the area, such as submerged obstacles, narrowing channels, or the presence of other vessels. The flashing nature of the light conveys urgency and emphasizes that operators should be vigilant and prepare to alter their course or speed if necessary.

This signaling is essential for maintaining safety on the water, as it provides a visual cue that may not be apparent through charts or other navigational aids. Recognizing this signal and understanding its implications enables mariners to navigate more safely in potentially hazardous situations.
