Yellow buoys serve as important navigational aids on waterways, guiding vessels and ensuring safe travel. They typically mark special areas such as no-wake zones, shallow waters, or underwater hazards like submerged rocks. Additionally, yellow buoys may designate regulated zones for activities like fishing, diving, or swimming. Their role in marine traffic management helps prevent accidents and ensures a safer experience for boaters and water users. Understanding their significance allows for responsible and informed navigation on lakes, harbors, and open waters.
