If your vessel must pass through a draw bridge during a scheduled closure period, what signal should you sound to request the opening of the draw?

🔍 Key Concepts

• Bridge sound signals used to request a drawbridge opening under 33 CFR (Navigation under bridges) • Difference between danger signal and request-to-open signal • Meaning of prolonged blast vs short blast in inland sound signals

💭 Think About

• Which sound signal pattern is specifically associated with communicating with a drawbridge tender, not with other vessels? • Which option represents a danger or doubt signal that would NOT normally be used just to request an opening? • Think about which patterns (prolonged + short blasts) are commonly used for maneuvering and which are reserved for special situations like bridges.

✅ Before You Answer

• Verify which signal in 33 CFR is defined as the standard drawbridge opening request signal • Make sure you are NOT choosing the signal that means "I doubt your intentions" or "danger" • Confirm that the correct pattern includes a prolonged blast combined with short blasts in the exact sequence required by the regulation
