A personnel carrying vehicle comprises a self propelled, steerable body, a telescoping mast attached to and extending upwardly from the body, and a personnel compartment attached to the mast. Two control handles are mounted within the personnel compartment, with one handle including a rocker mechanism mounted therein for pivotal movement within a generally horizontal plane to control steering and the other handle being rotated to controlling traction. Sensors ensure that the operator's hands are on both control handles and both feet are properly positioned on a floor of the operator's compartment before the vehicle can be moved or the platform raised; this ensures a four point stance, providing for operator stability and that the operator's hands and feet are within the operator's compartment anytime the vehicle is being moved or during lifting or lowering operations.
