INLAND ONLY Yellow lights are NOT used to...

🔍 Key Concepts

• Inland Navigation Rules – lights and shapes (focus on where yellow is specifically mentioned) • How towing vessels, fishing vessels (purse seiners), and dredge pipelines are marked at night • Standard navigation lights for aircraft or seaplanes on the water compared to vessels and obstructions

💭 Think About

• Look up where the Rules (or Annexes) explicitly mention yellow lights and list each type of vessel/structure they apply to, then compare that list to the answer choices. • Ask yourself: which of these options has its identification based on red, green, and white only, without any requirement for yellow? • Consider whether a pipeline on a trestle and a purse seiner have any special yellow-light requirements distinct from ordinary vessel sidelights and stern lights.

✅ Before You Answer

• Verify from the Inland Rules which categories definitely show yellow lights as part of their required identification lighting. • Check the standard navigation lights for a seaplane on the water and see if yellow is mentioned anywhere. • Confirm whether purse seiners and dredge pipelines have special provisions involving yellow in the Inland Rules or their Annexes.
