1. A system for a remotely controllable material handling vehicle switchable between a manual mode and a travel request mode, the system comprising:
a control handle configured to at least control a speed and direction of the material handling vehicle when the material handling vehicle is in the manual mode;
a remote control device in communication with the material handling vehicle and configured to provide a request to the material handling vehicle to move forward;
a mode switch configured to switch the material handling vehicle from the manual mode to the travel request mode; and
an operator compartment sensor configured to trigger a flag when a weight on a floor of an operator compartment of the material handling vehicle is greater than or equal to a predetermined weight, wherein when the material handling vehicle is in the travel request mode the operator compartment sensor is removed from communication with the material handling vehicle.
