Question 92 Rules of the Road

The correct answer is C) The location of vessels detected by radar. The International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, which govern the rules of the road for vessels, require that the location of other vessels detected by radar be taken into account when determining a safe speed. This is outlined in Rule 6 of both the COLREGS and the Inland Navigation Rules, which states that the safe speed of a vessel must be adapted to the prevailing circumstances and conditions, including the state of visibility and the proximity of other vessels. The other answer choices, while important factors to consider for safe navigation, are not specifically required by the rules when determining safe speed. The construction of the vessel (A) and the experience of the crew (B) are relevant considerations, but they are not the primary factors specified in the regulations. Option D, "all of the above," is incorrect because the location of vessels detected by radar is the specific factor required by the rules.
