Question 576 Rules of the Road

The correct answer is B) More than two vessels crossing. Under the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, the presence of more than two vessels crossing at the same location is considered a "special circumstance" that requires extra caution and coordination to avoid potential collisions. The other options are incorrect because: A) Speed in fog is a general rule, not a special circumstance. C) Two vessels meeting is a common situation covered by the rules, not a special circumstance. D) A vessel at anchor is a standard situation, not a special circumstance.
