Abstract: A simulated tubular member for use as part of a highway safety device wherein the tube is comprised of a stiff, resilient rod which provides rigidity to maintain the simulated tube in straight orientation during static conditions, but deflects upon impact to avoid destruction. The rod includes a plurality of plastic bulbs which are configured to provide the appearance of a hollow plastic tube in conformance with state and federal highway specifications.
