The guide board frame has an internal space and is fixed to the handrail of a bridge slab(1). The guide board is made of a board in which slow driving phrases are marked on the surface and supported in the guide board frame to protrude outside. An actuating wire(34) of a first shock-absorbing and sensing device is detachably connected to the bottom of the guide board with a safety pin.
