BOTH INTERNATIONAL & INLAND A vessel engaged in mine clearance operations shows special identity lights. Which is TRUE of these lights?

Correct Answer: Option A — they indicate that other vessels should not approach within 1000 meters

Annex V of the COLREGS specifies that vessels engaged in mine clearance must display three all-round green lights in a cross configuration. These lights indicate that other vessels should not approach within 1000 meters, as the operation poses a significant hazard to navigation due to the presence of explosive mines.
