Abstract: By law, a stand-up lift truck operator must be trained to keep both feet and legs located within an operator compartment. An exemplary operator presence detector includes multiple zones, or areas, configured to receive an operator's feet. A sensor arrangement detects the presence of the operator's feet and a logic device determines whether the operator's feet are present in the zones or areas in a predetermined configuration, such as a configuration that reinforces operator training to keep both feet in a designated area on a compartment platform. In preferred arrangements, based on whether the operator's feet are present in the zones in a predetermined configuration, at least one vehicle function is enabled or disabled which may serve to reinforce an operator's training to keep both feet and legs located within an operator's compartment.
