Further, the lower surface of the baffle plate 5 is flush with the lower surface of the indication board 3, so that the marks on the board surface of all indication boards 3 deviating from the driving direction of the vehicle are shielded. In this embodiment, the direction in which the vehicle travels is the direction in which the vehicle travels on the one-way running road surface to which the present apparatus is applied. Because the expressway is generally bidirectional, vehicles on a unidirectional running road surface where construction or traffic accident sites are located run in one direction, and vehicles on a side road surface run in the opposite direction, the judgment of drivers on the side road surface can be prevented from being influenced by the marks on the sign surface of the sign 3 deviating from the running direction of the vehicles through the structure.
