Which is a sign of safe boating operation?

Abiding by speed limits is a clear sign of safe boating operation because it ensures that the vessel is being operated in a manner that prioritizes safety for everyone on the water. Speed limits are established to reduce the risk of accidents, allowing operators to maintain control of their vessels and respond appropriately to other boats, obstacles, or adverse conditions. Operating within these limits helps prevent collisions and contributes to a safer environment for all boaters.

On the other hand, the other options present unsafe practices. Operating a vessel while intoxicated significantly impairs judgment and reaction times, increasing the likelihood of accidents. Ignoring navigation lights can lead to dangerous encounters, especially during low visibility situations, and not wearing personal flotation devices diminishes personal safety in case of an accident or emergency.
