A traction strip for vehicle driving wheels including a sheet of flexible material and a plurality of equally sized metal channels which are mounted in a contiguous spaced relationship on both sides of the sheet. The channels are mounted on the sheet in a back to back position, the free ends of the channels' side walls being directed away from the sheet so as to allow the upper channels to engage the vehicle wheels while the lower channels grip the road surface.
