🔍 Key Concepts

• Lockage priority rules used by the U.S. Army Corps of Engineers on inland waterways • How commercial traffic is treated compared with recreational/pleasure craft • Whether certain types of commercial cargo or operations (e.g., towing, hazardous cargo, passenger service) get higher priority

💭 Think About

• Among these four, which represent commercial traffic and which is purely recreational? • Between commercial vessels, which type of operation would authorities most want to move first for navigation efficiency and safety (consider hazardous cargo vs. passenger service vs. empty tow)? • Think about which vessel being delayed could cause the greatest operational or safety impact on the waterway system.

✅ Before You Answer

• Identify which of the four is not commercial traffic at all • Decide which of the commercial vessels (if more than one) might be moving hazardous or sensitive cargo • Recall that many lock systems intentionally give priority to certain commercial operations to keep commerce and safety flowing efficiently
