Question 509 Rules of the Road

The correct answer is A) has a tow that exceeds 200 meters in length. The shape shown in illustration D010RR is the "not under command" signal, which indicates that a vessel is unable to maneuver as required by the rules and is therefore not under command. Per the international and inland navigation rules, a vessel displaying this signal is required to indicate that it has a tow exceeding 200 meters in length. The other answer choices are incorrect because they do not accurately represent the meaning of the "not under command" signal.
