What condition should be checked on the trailer's landing gear?

The landing gear of a trailer plays a crucial role in supporting the trailer when it is unhooked from the tractor. For safety and functionality, it is essential that the landing gear is fully raised and free from any damage. This ensures that the trailer can be safely maneuvered and connected to the towing vehicle without any risk of the gear being caught on the ground or causing instability.

A fully raised landing gear also minimizes the risk of obstructions while driving and prevents wear and tear that could arise from dragging the gear on the ground. Additionally, checking for damage ensures that the landing gear can effectively support the trailer when parked. If the gear is compromised in any way, it could lead to dangerous situations, such as the trailer tipping or collapsing.

Other options, such as painting the gear or deeming it unnecessary, do not address the primary functional and safety considerations that must be checked during a pre-trip inspection. The focus should always be on complete functionality and safety of all components of the vehicle.
