Question 236Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND A "head-on" situation shall be deemed to exist at night when which of the conditions are met?
AI Explanation
The correct answer is D) both vessels sound one prolonged blast.
According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a "head-on" situation at night is deemed to exist when both vessels can see each other's sidelights and masthead lights, and both vessels sound one prolonged blast.
The other options are incorrect because: A) the distance between the vessels is not relevant in determining a head-on situation, and B-C) the visibility of the sidelights and masthead lights alone does not define a head-on situation, the sound signal is the key factor.
