Which organization typically governs the rules for distress signals?

The correct answer involves the International Maritime Organization (IMO), which is responsible for establishing global standards in shipping and safety at sea, including regulations related to distress signals. The IMO developed the International Convention for the Safety of Life at Sea (SOLAS), which outlines the protocols and signals that should be used during distress situations. This organization ensures that maritime safety procedures are internationally recognized and adhered to, thereby enhancing the safety of navigation and reducing the risk of maritime accidents.

The other organizations presented in the question have different roles. The Marine Safety Board is typically involved in investigating marine accidents and improving safety measures rather than directly governing distress signal regulations. The Coast Guard Communications Division plays an operational role in communications but does not set international maritime distress signal standards. The International Association of Lighthouse Authorities focuses primarily on the management and operation of lighthouses and navigational aids rather than distress signal governance. Thus, the IMO is the appropriate authority for establishing and overseeing the rules surrounding distress signals on a global scale.
