INLAND ONLY Vessels "A" and "B" are meeting on a river as shown in illustration D041RR below and will pass 1/4 mile apart. Which is one of the lights on vessel "B" that you will see if you are on vessel "A"?
Official USCG Answer & Rule Citation
Correct Answer: Option B — special flashing light
33 CFR 83.24(i) requires power-driven vessels operating on Western Rivers to display a special flashing light. This light is yellow, flashes at 50-70 flashes per minute, and is positioned to be visible from all directions, distinguishing these vessels from those operating under standard International COLREGS.
