    Abstract: My invention relates to a device for providing additional traction and grip for aiding an automobile which has been disabled by a rut or a slippery road surface or stuck in mud, sand or snow. The device provides a belt having a wedge-shaped appendage at one end so that, if the belt is pulled under the wheel, the spinning is reduced or stopped, and the wedge provides additional traction and lift to free the automobile.
