ABSTRACT:
A traffic control device constructed as a one-piece traffic channelizing device of a plastic material. The device includes a bottom having a plurality of flexible flap elements for receiving and storing a ballast thereon. The flexible flap elements are responsive to a substantial impact to the traffic control device to cause the ballast to be released from the flexible flaps while the device is impacted to a horizontal position adjacent its original position. The device is adapted to mount warning lights and to be stacked including with the warning lights mounted thereto. The stacking of the traffic control devices does not effect the desired action for the flexible flaps.
