PURPOSE: A self-supporting traffic safety sign is provided to restore a sign rod to an original position after being applied with a shock through a winding reel and a weight plumb and to prevent the sign rod from being detached due to the collision with a vehicle through a winding connection wire. CONSTITUTION: A self-supporting traffic safety sign comprises a sign rod(10), a bottom case(20), and a winding reel(30). The sign rod is internally equipped with a weight plumb(11) in the lower end and moves like a roly poly on the upper end of the bottom case by forming the lower side into a hemisphere. The bottom case comprises a second winding connection wire(32b) and is formed in the lower surface of the sign rod.
