An impact absorbing bar for a road with multiple dispersed vehicle impact is provided to minimize an impact caused by a vehicle collision by dispersing and absorbing the impact by plastic deformation, tensile deformation and elastic deformation. An impact absorbing bar for a road with multiple dispersed vehicle impact for absorbing and removing an impact caused by a vehicle collision with multiple dispersion like plastic deformation, elastic deformation and tensile deformation includes handrail posts(10) installed to the center or two sides of a road at regular intervals by a post support, a guard fence(20) opened at one side coupled to one or two sides of the handrail post and provided with a guard groove(24) to locate a tension absorber and an elasticity absorber, and an elasticity absorber(40) fixed between the guard fence and the handrail post together with a tension absorber(30) to make elastic deformation at a vehicle collision and provided with a support unit(42) bolted to the handrail post by a fixing bolt(46) and an elastic unit(44) coupled and supported to the guard groove of the guard fence by a support bolt.
