Semi-trucks are a common sight on the roads and highways of America. As such, it is important to know what kind of horn is on a semi-truck in order to make sure they are properly equipped with the right safety features. It is also important to understand the rules and regulations that govern the use of horns on commercial vehicles.
The different types of horns found on semi-trucks vary depending upon the truck manufacturer. However, all semi-trucks are required by federal law to have a loud device which emits an audible signal when activated.
This device is usually referred to as an air horn and produces a sound level of 110 decibels when activated. The noise produced by an air horn can be heard from up to one mile away.
In addition to an air horn, most semi-trucks also have a smaller bell or gong type horn mounted near the driver’s side door. This bell or gong type horn produces a much softer sound than the air horn, and it is typically used for signaling other drivers or pedestrians who may be in close proximity to the truck.
Electric Horns
Electric horns are also commonly found on semi-trucks, although they are not required by law. These horns produce a higher frequency sound than air horns and bells, making them more effective at getting the attention of other drivers or pedestrians. Electric horns can sound like a car horn, siren, or any other type of noise that can be electronically generated.
Conclusion
A semi-truck typically has two types of horns: an air horn which meets federal requirements and produces 110 decibels when activated; and a smaller bell or gong type horn which produces a softer sound for signaling other drivers or pedestrians nearby. Some trucks may also have electric horns installed which produce higher frequency sounds than either an air or gong type horn. Regardless of what kind of horn is used, all truck drivers must follow applicable laws and regulations regarding their use in order to ensure safety on the roadways for everyone.
