Indicator of the top of the surface that separates flows (protective bumper) is a product which has double function. It is made of such material that cushions crash, and it can amortize crash in a great measure if it is loaded with water or sand. His second function is traffic channeling with reflective fields. For that reason, it is mostly used for emphasizing bifurcations, e.g. exit ramps, traffic islands, toll booth lanes. The bumpers can be produced in different dimensions, related to location on which they are going to be placed, and also, they can be produced in required colour (orange or green).
