What should you be cautious of regarding non-lateral markers?

Non-lateral markers serve specific functions in boating navigation and can communicate various information to boaters. Among their several uses, one important aspect is that they can indicate limitations on speed. This means that certain markers may be placed to alert boaters about reduced speed zones due to proximity to sensitive areas, such as wildlife habitats or congested water traffic.

Markers may serve different purposes, such as designating no-wake zones, areas with specific speed limits, or other conditions that require boaters to exercise caution. This emphasis on the importance of adhering to speed restrictions helps promote safety on the water and protects both navigational integrity and aquatic ecosystems.

The other options present limitations and misunderstandings about non-lateral markers, such as suggesting they are the sole markers in an area, implying every hazard is marked, or asserting that they have no directional indications, which are not accurate representations of their function.
