🔍 Key Concepts

• Inland Navigation Rule 24 – Towing and Pushing (what the towed/pushed vessel shows, not the tug) • The definition of a composite unit vs. a barge simply pushed ahead • The purpose and placement of a special flashing light on inland tows

💭 Think About

• Focus only on the barge’s own required lights, not the tug’s lights. Which of these lights belong on the barge itself when it is pushed ahead? • Ask yourself: when a barge is pushed ahead (not part of a rigid composite unit), what light is used instead of a stern light to show its forward end in Inland waters? • Look at which answer choices include lights that would normally be found at the after end of a vessel and decide if that makes sense for a barge being pushed ahead.

✅ Before You Answer

• Verify in Inland Rule 24(e) what lights are required on a vessel or barge being pushed ahead (not a composite unit). • Check which answers include a special flashing light and recall its required use in Inland towing situations. • Make sure you are not adding lights that belong on the towing vessel (like towing lights) instead of on the barge being pushed ahead.
