Any stop or turn signal when required herein shall be given either by means of the hand and arm or by a signal lamp or lamps or mechanical signal device, but when a vehicle is so constructed or loaded that hand-and-arm signal would not be visible both to the front and rear of such vehicle then such signals must be given by such a lamp or lamps or signal device.
