🔍 Key Concepts

• Rule 34 – Maneuvering and Warning Signals (International Rules) • Use of light signals to supplement sound signals for overtaking/passing intentions at night • Difference between International and Inland rules for the color of passing-intention lights

💭 Think About

• Look up under the International Rules what kind of light signal is permitted to indicate overtaking or passing intentions in narrow channels at night. • Compare what colors are allowed for this light under International versus Inland rules—do both systems allow the same colors? • Ask yourself: is this light required to be a specific color, or are there options? Then match that requirement to the answer choices.

✅ Before You Answer

• Verify that the light used for passing intentions is described as all-round (visible through 360°). • Confirm from Rule 34 (International) exactly which color(s) are permitted for this maneuvering/passing light. • Make sure you’re not mixing in Inland provisions that allow an additional color choice not permitted Internationally.
