INLAND ONLY While underway during the day you sight a small motorboat showing a flashing blue light. What does the blue light indicate?

🔍 Key Concepts

• INLAND Navigation Rules on special flashing lights and color meanings • Difference between law enforcement vessels and Auxiliary/regatta patrol boats • Use of flashing blue lights on U.S. waters under Inland Rules

💭 Think About

• Think about which type of vessel is legally allowed to display a flashing blue light on Inland waters during the day or at night. • Consider how the Rules and 33 CFR treat law enforcement vessels versus Coast Guard Auxiliary or rescue boats in terms of light signals. • Ask yourself: if you see a flashing blue light, what are you expected to do as another vessel—does that match a race, a patrol, a rescue, or something else?

✅ Before You Answer

• Check in the Inland Navigation Rules/33 CFR which vessel category is expressly associated with a flashing blue light. • Verify whether Coast Guard Auxiliary and regatta patrol boats have different distinctive marks (flags, insignia) rather than a flashing blue light. • Confirm that a rescue boat or race committee boat, by itself, does not have the exclusive right to use a flashing blue light under Inland rules.
