🔍 Key Concepts

• INLAND ONLY light provisions in the Navigation Rules (Annex section on law enforcement vessels) • special flashing lights vs. normal navigation lights • how police / law enforcement boats are visually distinguished from other vessels at night

💭 Think About

• Which color of light is strongly associated with law enforcement on the water under Inland rules, and is it steady or flashing? • Look at each choice and ask: could a non–law enforcement vessel ever legally show this light or light combination for another purpose? • Which option is specifically described in the Inland Rules as being restricted to law enforcement, rather than just commonly used by them?

✅ Before You Answer

• Verify in the Inland Rules which color and flashing pattern is uniquely assigned to law enforcement vessels. • Check whether any of the other options are used for vessels not under command, towing, or special circumstances (these would NOT be law-enforcement-only). • Confirm that the correct choice is explicitly stated as “may be exhibited ONLY by” or similar wording for law enforcement vessels in the Inland text.
