🔍 Key Concepts

• Corps of Engineers lock VHF working channels used on inland rivers • Difference between Channel 16 (calling/distress) and lock "working" channels • How regional/inland VHF practices differ from coastal/harbor working channels

💭 Think About

• Think about which channels are commonly associated with locks and bridges on inland rivers, rather than harbors or offshore traffic • Recall which channels are designated as commercial/inland working channels in the VHF channel usage tables • Eliminate any options that include channels you normally associate with ship-to-ship safety, port operations, or Coast Guard liaison rather than lock operations

✅ Before You Answer

• Check which channels in the options are typically used for port operations and vessel traffic service (VTS) and rule those out for locks • Identify which set of channels in the answers are specifically marked in VHF guidance as "locks and dams" or "inland rivers" working channels • Verify that the channels you select are not primarily assigned to bridge-to-bridge (safety) or Coast Guard communications in most charts/tables
