A danger range can be labeled as NMT or NLT.

A danger range can be labeled as NMT or NLT.

• A. True
• B. Sometimes
• C. Depends
• D. False

Answer: (D)

Danger ranges are described by explicit distance bands, not by tolerance phrases. Not More Than and Not Less Than are used to express numerical limits on quantities (for example, a maximum speed or a minimum depth). They don’t describe a spatial zone around a hazard. If a danger range is present, it’s labeled with concrete distances—such as 0 to 2 nautical miles or from a starting bearing to an ending bearing—so mariners know exactly where the hazard exists. Using NMT or NLT would imply a limit on a quantity rather than a defined zone in the water, which is why this labeling is not appropriate.
