Question 679 Rules of the Road

The correct answer is A) do not impair the visibility or distinctive character of the prescribed lights. This is correct because according to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel may exhibit lights other than those prescribed by the Rules as long as the additional lights do not impair the visibility or distinctive character of the prescribed lights. The Rules are designed to ensure proper visibility and identification of vessels, so any additional lights must not interfere with this. The other options are incorrect because they do not fully capture the requirement for additional lights. Option B is too restrictive, while options C and D introduce additional criteria that are not part of the regulation.
