A rotating guard rail assembly formed preferably of steel tubing and sheathed in a polymerized material such as plastic. The assembly generally comprises a vertical stanchion sheathed in plastic and having a rotating jacket assembly mounted about the exterior of the stanchion. The jacket is free to rotate about the stanchion, thereby acting as a cornering or pivoting device to redirect a moving object upon impact of the guard rail assembly.
