Question 2 GLI02 - Mate of Unlimited Tonnage

The Correct Answer is A **Explanation for A (flashing blue light):** In the United States, law enforcement vessels (such as police boats or sheriff's patrol boats) operating on inland waters are typically authorized to display a **flashing blue light** when engaged in law enforcement duties, signaling the need for other vessels to yield or be aware of official activity. This usage is generally standardized across most U.S. inland waters and aligns with regulations that permit emergency/official vessels to use blue identification lights. **Explanation why other options are incorrect:** * **B) flashing amber light:** Amber (or yellow) lights are typically used for vessels restricted in their ability to maneuver, for towing operations, or for certain dredges/construction operations. They are not the standard identifying light for active law enforcement vessels. * **C) blue flag:** Flags are generally used for international signals (e.g., the 'A' flag for divers) or distress signals, or sometimes for race markers. A blue flag is not the standard or authorized visual signal used by a law enforcement vessel to indicate its status. * **D) flashing red light:** Flashing red lights are generally reserved for emergency vehicles on land. On water, constant red lights are used as sidelights (port side) or special warning lights (e.g., restricted maneuvering, if combined with white/red). A flashing red light is not the standard distinguishing light for a law enforcement vessel.
