🔍 Key Concepts

• Rule 14 – Head-on situation in the Navigation Rules • Meaning and visibility of sidelights (red/green) and masthead / towing lights • Relative bearing terms like “directly ahead” vs “on the beam”

💭 Think About

• Think about what you should see at night if another power-driven vessel is coming straight toward you on a reciprocal or nearly reciprocal course. • Ask yourself: in a true head-on situation between power-driven vessels, which navigation lights on the other vessel would be visible at the same time? • Consider which option describes a situation where risk of collision exists on nearly opposite headings, rather than crossing or overtaking.

✅ Before You Answer

• Review the exact wording of Rule 14 – Head-on situation (International & Inland) and note what lights are mentioned. • Confirm what combination of lights (red, green, white) you would expect when looking directly ahead at another power-driven vessel on a reciprocal course at night. • Eliminate any choice that clearly describes a crossing or towing situation rather than two power-driven vessels meeting end-on.
