When is it appropriate to use the horn on a forklift?

Using the horn on a forklift is crucial for ensuring safety in a workplace environment. The correct choice highlights that the horn should be utilized when approaching corners and pedestrian areas. This is important because these locations often have limited visibility, and there may be pedestrians or other equipment operators nearby. Using the horn alerts others to your presence, helping to prevent accidents and ensuring that those in the vicinity are aware of the forklift's approach, particularly in potentially hazardous situations.

In contrast, using the horn when driving in a straight line doesn't necessarily contribute to safety since visibility is typically clearer in straight paths. Employing the horn only during quiet times could diminish its effectiveness in more populated or busy settings. Finally, using the horn when the forklift is stationary does not serve a practical purpose, as there is no imminent risk to alert others to at that moment. Thus, the emphasis on using the horn during critical times, such as when approaching areas with potential pedestrian traffic, underscores a proactive approach to safety in the operation of forklifts.
