RedactedNarrative: Diversey Harbor which is equipped with a traffic light indicating when it is safe to enter the channel at the mouth of the harbor, similar to lock chamber lights. 
  
  Vessel 2 was being towed into the harbor when it was struck by Vessel 1. Vessel 2 was in the mouth of the harbor and Vessel 1 entered the channel.
  
   It is unclear whether Vessel 1 was being shown the red (give-way) light, or was being shown a green (stand-on) light. However, Vessel 1 entered the channel before the tow boat and Vessel 2 cleared the channel. 
  
  In proceeding into the channel, Vessel 1 failed to give-way to the vessel in distress. The two vessels collided and the Operator of Vessel 2 was struck by the Anchor of Vessel 1 causing injury to the operators left leg near the knee. 
  
   After the collision, Vessel 1 did not stop to render aid and did not submit a report to either CPD Marine Unit or Illinois Conservation Police. During interviewing, the Operator of Vessel 1 stated that he was unaware of the traffic signal and could not remember seeing one at all.
