Question 751 Rules of the Road
90% to passBOTH INTERNATIONAL & INLAND Vessel "A" is overtaking vessel "B" as shown in illustration D017RR below, and will pass without changing course. Vessel "B" is an air-cushion vessel operating in the non-displacement mode. Which light will vessel "A" observe from vessel "B"?
A
Green light
B
flashing red light
C
flashing yellow light
D
flashing white light
AI Explanation
The correct answer is C) flashing yellow light. According to the International Regulations for Preventing Collisions at Sea (COLREGS), an air-cushion vessel operating in the non-displacement mode is required to exhibit a flashing yellow light when overtaken by another vessel. This is specified in Rule 18(f) of the COLREGS. The other answer choices are incorrect because a green light is not a recognized signal for an air-cushion vessel, a flashing red light would indicate a vessel not under command, and a flashing white light is not the proper signal for an overtaking situation involving an air-cushion vessel.
