Which sound-producing device is required when boating on the Colorado River and Lake Systems in an 18-foot powerboat?

In Arizona, when operating an 18-foot powerboat on the Colorado River and its associated lake systems, it is mandated to carry a sound-producing device. The requirement specifies that this device can be a whistle, horn, or another form of sound-producing device, which serves an important safety function. Sound signals are crucial for communication between vessels and alerting others to your presence or intentions, especially in situations where visibility is limited or in crowded areas.

Using a general term like "whistle, horn, or other sound-producing device" encompasses a range of options, thereby allowing boaters flexibility in meeting safety regulations. This ensures that they can choose a device that suits their needs, whether it be a traditional horn, a handheld whistle, or any other compliant device, thereby making it easier to adhere to safety standards while ensuring the ability to communicate effectively on the water.
