What are non-lateral markers primarily used for?

Non-lateral markers are specifically designed to convey regulatory and informational guidance about waterways, rather than to indicate navigational routes like lateral markers do. They serve important functions such as communicating speed limits, no-wake zones, or restricted areas, as well as providing information about hazards or points of interest along the waterway. This makes option B the most accurate description of their purpose.

While lateral markers are focused on establishing safe navigation routes, options related to fishing zones and emergency areas are served by other types of specialized buoyage or marker systems. Non-lateral markers have a broader regulatory purpose, reinforcing safe boating practices and environmental stewardship, ensuring boaters have the necessary information to navigate safely and responsibly in specific water areas.
