What does a square non-lateral marker generally indicate?

A square non-lateral marker is primarily used to convey directions and information to boaters on the water. These markers are typically found in various colors, often emblazoned with symbols or text that provide important information regarding navigation, speed limits, or nearby facilities. For instance, they might inform boaters of the location of a marina or the presence of a waterway that is safe to traverse.

Understanding the function of square non-lateral markers is vital for safe boating practices as they help ensure that boaters can navigate waterways effectively while adhering to region-specific regulations or guidelines. The other types of markers serve different purposes: hazard and obstruction markers warn about potential dangers, controlled area markers indicate places where certain restrictions are enforced, while danger zones highlight particularly risky areas to avoid. Each category has its distinct visual characteristics and specific meaning, but the square non-lateral marker is specifically designed to inform and guide, which is why it is associated with directions and information.
