Question 207 Rules of the Road

90% to pass

INLAND ONLY You are meeting "head-on" a tug towing a barge alongside about a mile away. In addition to the white masthead lights which other lights do you see on the tug and tow combined?

A One green and one red sidelight on the outside of the unit
B Only the green and red sidelights marking each vessel
C The green and red sidelights marking each vessel and a special flashing light
D One green and one red sidelight and a special flashing light
AI Explanation

The correct answer is C) The green and red sidelights marking each vessel and a special flashing light. This is the correct answer because according to the Inland Navigation Rules, a tug towing a barge alongside would display, in addition to the required white masthead lights, the green and red sidelights marking each vessel (the tug and the barge) as well as a special flashing light to indicate the vessel is restricted in its ability to maneuver. The other answer choices are incorrect because option A only includes the sidelights on the outside of the combined unit, option B is missing the special flashing light, and option D is missing the sidelights on the barge.
