Sound Signal Devices

In periods of reduced visibility or whenever a vessel operator needs to signal his or her intentions or position, a sound-producing device is essential. The navigation rules for meeting head-on, crossing, and overtaking situations are examples of when sound signals are required. However, you are prohibited from sounding a sound-producing device while within any harbor limits or while in congested waterway traffic.

  • On Oklahoma state waters, follow these requirements for sound-producing devices.
    • Vessels less than 26 feet in length, which includes PWCs, are required to carry on board a whistle or horn or some other means to make an efficient sound signal.
    • Vessels that are 26 feet or more in length are required to carry on board a whistle or horn, and a bell.
  • On federally controlled waters, follow these requirements for sound-producing devices.
    • Vessels less than 65.6 feet (20 meters) in length, which includes PWCs, are required to carry on board a whistle or horn or some other means to make an efficient sound signal audible for at least one-half mile.
    • Vessels that are 65.6 feet (20 meters) or more in length are required to carry on board a whistle or horn, and a bell that are audible for at least one mile.
  • No vessel may be equipped with a siren except vessels used by law enforcement officers.
