Question 2 ONC07 - OUPV-Near Coastal

The Correct Answer is A **Explanation for Option A (flashing blue light):** A flashing blue light is the distinctive and recognized signal authorized for display by law enforcement vessels (police boats) while actively engaged in official duties, such as enforcement or pursuit, particularly in inland waters. This light is used to signify the boat's status as an official law enforcement patrol. **Explanation for Option B (flashing amber light):** A flashing amber (or yellow) light is typically used by boats restricted in their ability to maneuver (like dredging or survey vessels) or by certain types of tow operations to indicate their specific status or work area. It is not the standard distinguishing light for law enforcement patrol vessels. **Explanation for Option C (blue flag):** While flags are used on vessels for various signaling or decorative purposes (e.g., diver down flags, courtesy flags), a blue flag is not a federally regulated or universally recognized navigational aid used specifically and exclusively to identify an active law enforcement boat for navigational purposes. Law enforcement status is communicated primarily through lights and markings. **Explanation for Option D (flashing red light):** A flashing red light is typically used in specific circumstances, such as by Coast Guard vessels on safety patrols or by certain types of emergency or distress signals (like flares). While red lights are part of the required navigational sidelights, a *flashing* red light is not the standard identifying signal for a general law enforcement patrol boat.
