Which statement describes regulatory markers?

• A. They are red buoys only.
• B. They indicate local hazards to navigation.
• C. They are white buoys or spars with orange symbols.
• D. They provide general information, information on rules, or indicate local dangers to navigation.

Answer: (D)

Regulatory markers are the aids to navigation that convey what you can or cannot do in a given area, and they also warn about local hazards. They’re designed to inform mariners about applicable rules, restrictions, and dangers, which is why they’re described as providing information on rules and hazards. They’re not limited to a single color or type, and focusing only on their appearance misses the purpose behind them. In practice, you use these markers to understand the regulations that apply in the area and to recognize any dangers you should avoid.
