(a)In addition to the conventional signals, aids to navigation marking the Intracoastal Waterway exhibit unique yellow symbols to distinguish them from aids marking other waters.
(1)Yellow triangles indicate that aids to navigation so marked should be passed keeping them on the starboard (right) hand of a vessel, regardless of the aid's number, color, or light color.
(2)Yellow squares indicate that aids to navigation so marked should be passed keeping them on the port (left) hand of a vessel, regardless of the aid's number, color, or light color.
(3)A horizontal yellow band provides no lateral information, but simply identifies aids to navigation as marking the Intracoastal Waterway.
(b)The above guidelines apply for vessels traversing the Intracoastal Waterway in a southerly direction on the Atlantic Coast, in a westerly direction on the Okeechobee Waterway, or in a westerly direction along the Gulf Coast.
