What is the purpose of the horn on a telehandler?

The purpose of the horn on a telehandler is primarily to alert personnel nearby of potential hazards. This function is crucial for safety in environments where telehandlers operate, often close to other workers and equipment. The use of the horn serves to warn individuals of the telehandler's presence, especially in situations where visibility may be limited or when the machine is moving in close quarters.

Typically, the horn is an essential safety feature that helps prevent accidents by giving a warning signal that can alert nearby personnel to move away from the machine's path or to make them aware of the telehandler's operations. This not only protects the workers on-site but also facilitates smoother operations by communicating intentions when moving or performing other tasks with the equipment.

The other choices, while they might relate to operational safety in some capacity, do not accurately represent the primary function of the horn. For instance, using the horn specifically for signaling when reversing is a specific application rather than its overall purpose. Similarly, an indication of engine temperature is typically addressed by instrumentation rather than an audible alert, and the visibility at night is usually enhanced through lights rather than the horn itself.
