Question 326 Rules of the Road

The correct answer is A) when being pushed ahead. According to the Inland Navigation Rules, a vessel being pushed ahead is required to exhibit a special flashing light. This helps to identify the vessel's mode of propulsion and ensures other vessels in the area are aware that the vessel is being pushed, rather than being self-propelled or towed. The other options are not correct because they do not require the use of a special flashing light. Vessels at anchor in a fairway are required to exhibit the appropriate anchor lights, and towed vessels are not required to exhibit a special flashing light.
