🔍 Key Concepts

• International vs. Inland Rules for towing and pushing operations • Special lighting patterns for pushing ahead and towing alongside • How barges show lights when pushed ahead on inland vs. international waters

💭 Think About

• Ask yourself which of these situations have specific Inland-only provisions compared to the International Rules • Consider whether the lighting changes for the towing vessel, the towed unit (like a barge), or both • Think about whether the same basic towing lights apply in both waters, or if Inland waters allow or require alternative combinations

✅ Before You Answer

• Review the Inland Rules section on Inland-only lights for composite units and pushing ahead • Compare the lighting for barges in tow in International vs. Inland waters • Verify whether all three situations listed are treated differently, or if only some have distinct Inland provisions
