Abstract
A stationary board adapted to be set up in a medial strip between traffic lanes to block lights of oncoming vehicles in the medial strip and facilitate identification of the medial strip in nighttime driving or riding. This stationary board comprises a pair of plate members each composed of a molded component made of a transparent plastic material, and the plate members are coupled with one another at the respective marginal edges thereof to form an integrated assembly having a hollow space therein. Each of the plate members is formed with irregularities in its inner surface facing the hollow space of the assembly. A top member molded of a plastic material is attached to the top portion of the assembly in a fitting manner. The plastic material of the top member contains a luminous pigment capable of absorbing, storing and emitting light. The stationary board of the present invention can bring out a function of facilitating identification of the medial strip in nighttime driving or riding as well as blocking lights of oncoming vehicles, while offering excellent aesthetic appearance.
