Question 515 Rules of the Road
90% to passBOTH INTERNATIONAL & INLAND At night, power-driven vessels less than 12 meters in length may, instead of the underway lights for vessels under 50 meters, show which lights?
The correct answer is C) One all-round white light and sidelights. According to the International Regulations for Preventing Collisions at Sea (COLREGS), power-driven vessels less than 12 meters in length may, at night, show one all-round white light and sidelights instead of the full set of underway lights required for vessels under 50 meters. This simplified lighting configuration is allowed for smaller vessels as a practical alternative to the standard underway lights. The other options are incorrect because: A) Sidelights and stern light do not meet the COLREGS requirement for an all-round white light, B) Stern light only is insufficient, and D) Masthead light only does not provide the necessary sidelights.
