A battery-powered four-way load handling vehicle has a chassis with a pair of front wheels 101, 103 and a rear wheel (105, Figure 1), with the rear wheel and at least one front wheel being powered by a wheel motor with a wheel motor controller for controlling the wheel motors. The vehicle is operable in a forwards/backwards mode of operation and a sideways mode of operation. In the sideways mode of operation, when a front steering wheel 101 is turned so that the rear wheel is on the inside of the turn, the wheel motor controller slows the rear wheel gradually with increasing degree of turn until the front steering wheel reaches a critical angle at which the rear wheel is stopped, and the rear wheel is placed into a freewheeling mode in which it can move in reverse. In the forwards/backwards mode a front wheel on the inside of the turb may similarly be made to freewheel at a critical angle.
