You are approaching a drawbridge and must pass through during a scheduled closure period. What signal should you sound?

🔍 Key Concepts

• 33 CFR Part 117 – Drawbridge Operation Regulations • Sound signals used to request bridge openings versus signals for danger or doubt • Difference between prolonged blasts and short blasts and when each is used

💭 Think About

• Ask yourself: Which of these signals is specifically described in regulations as a request for bridge opening during a closure period? • Think about which signal is normally used to say “I don’t understand your intentions or I doubt your actions” and eliminate that choice. • Consider what type and sequence of blasts (prolonged vs short) are typically associated with bridge-to-vessel communication, not vessel-to-vessel maneuvers.

✅ Before You Answer

• Verify in 33 CFR Part 117 which sound signal a vessel must use to request a drawbridge opening during a restricted period. • Identify which option is the standard danger/doubt signal and rule it out for this question. • Check that the signal you choose is not one of the common maneuvering signals (like port/starboard altering course).
