What should be checked to ensure the safe operation of vehicles during loading?

Checking the brakes of vehicles during loading is crucial for ensuring safe operation. The brakes are a key component of vehicle safety because they enable the operator to stop the vehicle effectively, especially when carrying heavy loads or navigating tight spaces. In a loading environment, where vehicles may be moving in close proximity to personnel and equipment, ensuring that the brakes are fully functional helps prevent accidents and enhances overall safety.

Though fuel levels, tire pressure, and engine temperature are also important aspects of vehicle maintenance and operation, they do not directly pertain to the immediate safety of maneuvering the vehicle during loading activities. Properly functioning brakes are essential to control the vehicle's movement and to prevent it from rolling or colliding with other objects or personnel in the busy loading area.
