Signs do indeed "wear out." Signs are required to meet certain standards of reflectivity and need to be replaced when they do not. The reflective materials signs are made from are good for about 5 or so years. Many jurisdictions don't necessarily replace signs when they should but they are supposed to. Some states like Florida are aggressive about sign replacement. This rule applies to regulatory and warning signs, not guide signs. Phil
