None of the provisions of this section prohibit the placing of public notices on billboards erected for that purpose by authority of the governing body of a municipality. Any advertisement in or upon a public highway or private property which, in the judgment of the director, may be deemed to be a hazard to traffic, or in the future may tend to create a hazard to traffic, may be taken down, removed, or destroyed by direction or authority of the department in the case of the state highway system, by the board of county commissioners in the case of the county road system, and by the board of township supervisors in the case of township roads.
