Question 900 Rules of the Road
90% to passBOTH INTERNATIONAL & INLAND In a crossing situation, which vessel may sound the danger signal?
The correct answer is A) Either vessel. According to the International Regulations for Preventing Collisions at Sea (COLREGS), both the give-way vessel and the stand-on vessel are permitted to sound the danger signal (five or more short, rapid blasts on the whistle) if they believe there is a risk of collision. This applies to both international and inland navigation rules. The other options are incorrect because: B) Neither vessel should not sound the danger signal if they believe a collision is imminent; C) Only the give-way vessel is not required to sound the danger signal; and D) The stand-on vessel is also allowed to sound the danger signal if necessary, not just the give-way vessel.
