Abstract: An improved portable traction track for a vehicle driving wheel which is characterized by a plurality of base sections flexibly connected to one another to form an elongate strip adapted to be pulled under a rotating driving wheel. Each of the base sections include transversely spaced vertical side walls which have longitudinally spaced edges which are disposed in predetermined angular relationship to the edges of the immediately adjacent side walls in a decreasing angular relationship from the front toward the rear of the strip. The edges of the side walls are also provided with locking features such that upon flexing of the base sections in one direction, the side sections engage one another to permit only predetermined amount of flexing of that portion of the strip. This construction provides a bridge effect as the vehicle wheel rotates and pulls the strip under the wheel to the point at which the wheel is driven out of the rut in which it is stuck.
