INLAND ONLY Yellow lights are NOT used to identify which of the following?

Correct Answer: Option A — A seaplane on the water

33 CFR 83.23 (Rule 23) and Annex V specify that yellow lights are used for towing, dredging, and special operations. A seaplane on the water is not required to display yellow lights; it must display navigation lights as prescribed by Rule 23, which does not include yellow.
