🔍 Key Concepts

• Rule 10 – Traffic Separation Schemes in the Navigation Rules • The basic purpose of a traffic separation scheme • Whether a look-out can ever be omitted under the Rules

💭 Think About

• Ask yourself: What is the main safety benefit of a traffic separation scheme—what problem is it designed to reduce? • Which choices sound like they change or weaken other fundamental Rules, such as the requirement for a proper look-out? • Which options describe things that might be done by a port authority or company, versus what Rule 10 actually defines on the chart?

✅ Before You Answer

• Verify what a traffic lane and separation zone are intended to do in Rule 10 • Check if the Rules anywhere allow you to dispense with a proper look-out because of a routing system • Confirm which option matches how traffic separation schemes are shown on charts (inbound/outbound lanes, separation zones, etc.) rather than operational company policies
