Traffic barricade

A traffic barricade^[1] is a type of barricade used to control the flow of traffic or block access to an area, generally for safety purposes. Traditionally made of wood, or wood and steel, many now have structural members made wholly of plastic or composite materials, and may be fitted with flashing lights.

The obstruction that necessitates the use of a traffic barricade may be excavations, construction, roadblocks, debris, crime scenes, restricted areas, or other hazards.
