1. A method for controlling a vehicle, comprising: inspecting a work area prior to operation of the vehicle in the work area to identify at a non-traversable area that the vehicle cannot traverse safely or expediently; establishing, via a user interface, a boundary around the non-traversable area within the work area based on the inspection; determining a position of the vehicle via a location-determining receiver; and generating a warning alarm to an operator if the determined position of the vehicle traverses the boundary.
