A traffic cone comprising a base and a standard upstanding therefrom is given improved stability or strength by being moulded from plastics material as an integral article or by modification of the structure or dimensions of the base. The cone can be given further increased stability by the use of a collar on the base and which, like the base, can contain ballast. The cone can be used with boards to construct barrier systems. <IMAGE> |
