What lights would you see on the Illinois water way... - USCG Navigation General

What lights would you see on the Illinois water way when any wickets of the dam or bear traps are open, or partially open, which may cause a set in the current conditions in the upper lock approach?

A Red over amber (yellow)

B Red over blue

C Green over red

D None of the above

AI Explanation

The correct answer is A) Red over amber (yellow). When any wickets of a dam or bear traps are open or partially open on the Illinois Waterway, it can create a set in the current conditions in the upper lock approach. According to the Inland Navigation Rules, the proper light display to indicate this condition is a red over amber (yellow) signal light. This alerts mariners to the presence of strong or dangerous currents in the area, allowing them to navigate cautiously. The other answer choices are incorrect because they do not match the specific light display required for this situation on the waterway.
