🔍 Key Concepts

• Lock traffic signal meanings used by the U.S. Army Corps of Engineers on rivers • How a flashing red light is treated in navigation and road traffic (stop / do not proceed) • The difference between "approach under control" and actually entering the lock

💭 Think About

• Ask yourself: when a lock shows flashing red, is the chamber open and ready for you, or is it closed/not available? • Think about what the lockmaster needs to do before you are authorized to approach the lock wall or enter the chamber. • Consider which option best matches the idea of waiting for permission versus moving toward the lock without it.

✅ Before You Answer

• Verify what a red flashing lock light indicates in inland lock regulations (ready to enter, or do not enter?). • Check which choice clearly means you will not attempt to enter or interfere with traffic until the signal changes or you get instructions from the lockmaster. • Make sure the option you choose keeps your vessel safely clear of the lock and dam while you wait.
