INTERNATIONAL ONLY Which is TRUE for a light used to signal passing intentions?

A The light must be an alternating red and yellow light
B The light must be an all-round white or yellow light
C The light must be an alternating white and yellow light
D The light must be an all-round white light only
AI Explanation

The correct answer is D) The light must be an all-round white light only. The International Regulations for Preventing Collisions at Sea (COLREGS) state that a light used to signal passing intentions must be an all-round white light. This is specified in Rule 34(c) of the COLREGS, which governs the use of signals to indicate a vessel's maneuvering intentions. The other options, such as using alternating red and yellow or white and yellow lights, do not comply with the COLREGS requirements for signaling passing intentions.
