Abstract
The invention consists of a plurality of hinged panels including side rails where the panels on each end are shorter in length than the panels between them. The panel on one end is shorter in length than the panel on the other end. Both end panels are tapered in thickness and in with. The top surface is covered with projects forming rectangular cavities with the top of the long sides higher at the ends than in the mid-section. The bottom surface includes fasteners for removably attaching cleats for gripping slippery surfaces. A variety of cleats are proposed for securing the mat under different conditions. Bracing arms are provided to support the mat in an upright position when it is used as a highway warning marker. The mat is brightly colored for daytime use and the side rails and bracing arms are covered with light reflective material for use during the hours of darkness. The panels are so hinged that one half will fold over the remaining half without interference for storage.
