Question 333 Rules of the Road

The correct answer is C) 2 short blasts. According to the Inland Navigation Rules, when a power-driven vessel intends to overtake another power-driven vessel on the overtaken vessel's port side, the overtaking vessel must sound 2 short blasts to signal its intention. This whistle signal communicates to the overtaken vessel that the overtaking vessel wishes to pass on the port side. The other answer choices are incorrect because they do not match the specific whistle signal required by the Inland Navigation Rules for this overtaking scenario. 1 short blast, 1 prolonged and 1 short blast, and 2 prolonged and 2 short blasts are not the correct signals for this situation.
