A8 (Warning—Uneven road) is a Swedish road sign, belonging to the category of warning signs (group A). Closer provisions are given in the road sign ordinance (SFS 2007:90): The sign indicates that the roadway is uneven or damaged to such a degree that it is appropriate to travel at a lower speed than would otherwise have been the case.
