Where is the Red Navigational light located?

• A. On the port side
• B. On the starboard side
• C. At the stern
• D. At the bow

Answer: (B)

Red navigational light is placed on the port (left) side of a vessel when you’re looking forward. This color coding helps other mariners quickly judge which side you’re on at night or in poor visibility: red on the port side, green on the starboard (right) side, with a white light at the stern. Knowing where the red light sits lets you determine whether another vessel is to your left, and it supports safe passing and right-of-way decisions. The red light is specifically on the port side, not on the stern or bow, and it is paired with the green light on the opposite side.
