Question 2 UFV01 - Master - Uninspected Fishing Vessels

The Correct Answer is A **Explanation for Option A (flashing blue light):** In many jurisdictions, particularly under rules governing inland waters (such as U.S. Inland Navigation Rules), a law enforcement vessel may display a **flashing blue light** as an identification signal while engaged in official duties. This signal is often used to distinguish it from a federally operated vessel or a vessel engaged in a specific activity like dredging or towing, which use other colored lights (yellow, red, or white). **Explanation of Incorrect Options:** * **B) flashing amber light:** A flashing amber (or yellow) light is typically reserved for vessels constrained by their ability to maneuver, such as those engaged in dredging, surveying, or towing operations that severely restrict the movement of other vessels. It is not the standard identifying signal for law enforcement. * **C) blue flag:** A blue flag (or blue shape) is the required signal used on a vessel when a vessel is transferring or handling dangerous cargo, preparing to receive or discharge fuel, or when an explosives anchorage is being used. It has no relation to a law enforcement vessel's official duties or identification. * **D) flashing red light:** Flashing red lights are often associated with distress signals (if combined with other signals), emergency vehicles on land, or certain restricted visibility signals (such as those indicating a vessel is not under command). In the context of inland rules, a flashing red light is not the prescribed identification signal for a law enforcement boat.
