🔍 Key Concepts

• Distress signals under the Navigation Rules and International Regulations (COLREGS) • Different types of signals used to indicate distress: visual (seen), sound (heard), and smoke/day signals • The idea that distress can be communicated by more than one method

💭 Think About

• Look at each choice and ask: Is this something that could reasonably attract attention and indicate a vessel is in trouble? • Think about both daytime and nighttime situations: which types of signals work in each case? • Recall from your studies: Are distress signals limited to just one medium (only light, only smoke, or only sound), or can multiple media be used?

✅ Before You Answer

• Verify which items are specifically listed as recognized distress signals in your study materials or Navigation Rules annexes. • Check whether all of the listed options can be used to attract attention and request assistance at sea. • Confirm whether exam questions on distress signals usually focus on a single best type or on the idea that several different methods qualify.
