An information board, particularly intended for road users, comprises a plane sheet (10), the front side of which is provided with the necessary information, and at least one supporting post (17) to which the sheet (10) is attached. The sheet has a lower horizontal edge which is flanged to form a flange (10a) projecting from the back of the sheet substantially perpendicularly to the plane of the sheet. The plane sheet (10) is on its back provided with a profiled plate (18) resting on the projecting flange (10a) and covering substantially the whole back of the sheet, thus reinforcing and stiffening the information sheet. |
