🔍 Key Concepts

• Radar requirements for towing vessels in 46 CFR (Inland towing regulations) • Difference between assistance towing vs. regular commercial towing • How length of vessel and route (Western Rivers) can affect equipment requirements

💭 Think About

• Which of these options describes a specific regulatory exemption rather than just a common operating condition? • Does the regulation generally start by requiring radar for towing vessels and then carve out narrow exceptions, or does it broadly exempt whole categories like all small or river-only tugs? • Think about the risk: which of these operations would regulators most likely consider lower-risk and therefore possibly exempt from carrying radar?

✅ Before You Answer

• Check 46 CFR requirements for towing vessel radar and look for any explicit exceptions by type of service (e.g., assistance towing). • Verify whether there is a blanket exemption based only on vessel length or operating area (Western Rivers), or if the rule is more specific. • Confirm that the condition in the correct option is worded almost exactly like the regulatory language rather than sounding like a general description.
