Road signs expressing information about the type of road, how to use the road and telling about objects on the road or in its vicinity.
They have a rectangular shape with a dark blue border and white background (even if only the image itself is a dark blue shield) or with a white background and black image.
Under the information signs they can be placed various signs with specific information. This information can not be placed directly on the mark. Only characters from D-15 to D-17 have their own compilations indicating that the stop could be for two or three vehicles performing transport payable on regular lines.
