ABSTRACT:
A traction mat for vehicles has panels of flexible resilient material interconnected by sets of overlapping links which enable the panels to be folded in a stacked arrangement.
Recesses or slots in the upper faces of the panels provide grip for a vehicle's tires and holes in the panel enable the panel to be pushed down through mud to a solid surface.
