Sign R-411 is a vertical mandatory sign, recognizable by its circular shape with a blue background and white characters. This sign establishes the obligation for drivers to travel at least at the speed in kilometers per hour indicated by the figure, from the place where it is located until another end of minimum speed sign appears or a different regulation applies. It must not be confused with the maximum speed sign (circular with a red border) or with the recommended speed sign (square with a blue background).
