I see 1 red light and 2 yellow lights, what should I do?
Bridge Transmission
Ahoy! You are likely observing a vessel engaged in a specific activity. According to COLREGs, a red light alone usually indicates the port side. However, two yellow flashing lights (side by side) often signal a high-speed craft in non-displacement mode.
**Action Required:**
1. Maintain a sharp lookout and check for CPA (Closest Point of Approach).
2. In a crossing situation, if the red light is on your starboard, YOU are the give-way vessel.
3. Alter course to starboard to pass at a safe distance. Stay clear of the high-speed craft's lane.
