What feature helps a forklift operator determine the load's position?

The load backrest extension is a critical feature that assists a forklift operator in determining the load's position. It provides support to the load being carried, preventing it from falling backward and giving the operator a reference point to gauge how far the load extends behind the forklift. This is particularly important when maneuvering in tight spaces or when stacking loads, as it helps ensure that the load remains stable and correctly positioned during transport.

While other options such as load indicator lights, side mirrors, and forklift camera systems also contribute to safe forklift operation and awareness, they serve different primary functions. Load indicator lights typically signal weight or load status, side mirrors provide visibility of surroundings, and camera systems enhance overall awareness by displaying views not easily seen from the operator's position. The backrest extension, however, is specifically designed to assist in managing the load's position and securing it during movement.
