🔍 Key Concepts

• Inland Navigation Rules – Lights for law enforcement and public safety vessels • Difference between law enforcement lights and public safety/commercial vessels • Special flashing or alternating lights that might be confused with police, fire, or ambulance vehicles ashore

💭 Think About

• Think about which color combinations are typically reserved for law enforcement vessels under the Inland Rules • Ask yourself which option could cause confusion with emergency vehicles on land if used by any commercial vessel • Consider whether the Inland Rules allow commercial public‑safety vessels to display the same lights as regular police boats

✅ Before You Answer

• Verify what color flashing lights are specifically authorized for law enforcement vessels only in the Inland Rules • Check whether any option mentions alternating red and blue or similar patterns that might be restricted to official police use • Confirm which color, when flashing by itself, is associated with public safety or caution rather than police or emergency authority
