An earth-moving vehicle (1) is provided with a device (20) for configuration of the profile of the vehicle for circulation on the road. The vehicle (1) is provided with an operating arm (3), which moves under the action of hydraulic cylinders, on at least one of which (8) the configuration device (20) operates for setting at least part (4b, 5) of the operating arm (3) in a predetermined reference position so as to enable circulation of the vehicle (1) on the road. The configuration device (20) is provided with a sensor (22) designed for detecting the position of the operating arm (3) and for issuing a corresponding signal, according to which a control valve (19) is switched automatically in order to disable actuation of the cylinder (8) when the operating arm (3) reaches the aforesaid reference position. The configuration device (20) is moreover equipped with a re-enabling member (30, 32), controlled manually by the driver to switch the control valve (19) back to an enabling position and to restore the possibility of actuating the cylinder (8).
