Question 136 Rules of the Road

The correct answer is B) make sure the action is taken in enough time. The key requirement when taking action to avoid collision under both the International and Inland Navigation Rules is to ensure that the action is taken in enough time. This allows the other vessel(s) involved to clearly observe the action and respond accordingly, thereby reducing the risk of a collision. The other options are incorrect because: A) making large speed changes may not always be necessary or desirable to avoid a collision; C) making large course changes may be necessary in some situations, but the timing of the action is the critical factor; and D) while all of the options may be relevant in certain situations, the most important requirement is to take action in enough time.
