Sound Signals

Sound signals used on the waterways are like the turn light indicators used to signal intentions on the highways. Sound signals are also like an automobile's horn used to let other drivers know you are near or to alert them of danger. All boaters should know proper sound signals, especially those boaters operating near commercial vessel traffic.
