Question 70 Rules of the Road

The correct answer is D) navigating in or near an area of restricted visibility. The steering and sailing rules for vessels in restricted visibility, as defined in the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, apply to all vessels navigating in or near an area of restricted visibility, regardless of whether they are in sight of one another or have operational radar. These rules are in place to ensure the safe navigation of vessels in conditions where visibility is limited, such as fog, mist, or heavy rain. The other answer choices are incorrect because they do not accurately reflect the scope of the steering and sailing rules for restricted visibility. Vessels in sight of one another in fog (option A) are still subject to the rules, as are vessels without operational radar (option B). Special purpose lights (option C) are not a prerequisite for the application of these rules.
