摘要:
A temporary road maker is provided with one or more transparent protective covers covering a reflection of the road marker, wherein each protective cover is provided with a separate pull-tab located at a unique location with reference to the pull-tabs of other protective covers to facilitate the rapid removal of the outermost protective cover whenever said protective cover is coated with road resurfacing material and thereby is obscuring the reflective portion of the temporary road marker.
