What should the driver of the stacker do when stacking goods on the trailer?

When stacking goods on a trailer, it's essential to ensure that the trailer is level. A level trailer provides a stable base for the stacked goods, which reduces the risk of items shifting or falling during transport. An unlevel trailer can make it difficult to balance the load, potentially leading to accidents or damage to both the goods and the trailer itself.

Checking the trailer tires is certainly important for overall safety and functionality; however, it does not specifically address the critical factor of load stability when stacking. Ensuring that the load is well-balanced and secure on a level surface is vital for safe operations in this context.
