Regulation 17
1. The map shall clearly indicate by distinctive colours, symbols or markings each road to which the designation use order or speed order relates.
2. Where the map is neither specifically referred to in the text of the designation, the use order or the speed order, nor made a part of the designation, the use order or the speed order, it shall be for the purposes of illustration only and the matter indicated on it shall not prevail over the text in the event of any discrepancy between the map and the text.
