While proceeding downriver, you sight a red triangular-shaped daymark on the left bank. What does this daymark represent under the U.S. Aids to Navigation System on the Western Rivers?

🔍 Key Concepts

• Western Rivers aids to navigation and how they differ from other U.S. waters • Meaning of red triangular daymarks in the lateral system • How "proceeding downriver" affects which side of a channel an aid marks

💭 Think About

• Think about what red aids (nun buoys or triangular daymarks) generally indicate in the U.S. lateral system and which side of the channel they mark when going downstream on Western Rivers. • Ask yourself: on the Western Rivers, does a red daymark on the left bank mean you should keep it on your port side, starboard side, or does it mark something else entirely? • Consider whether a red triangular daymark on the bank would be used to indicate a preferred side of channel at a bend, a place to cross the river, or simply a lateral boundary.

✅ Before You Answer

• Verify how red vs. green aids mark the channel on Western Rivers when proceeding downstream. • Confirm what the terms crossing versus passing daymark mean in river navigation context. • Make sure the choice you select actually describes a lateral aid function, not a non-lateral or special-purpose aid.
