§ Mr. Chope
Traffic restrictions, including stopping and parking provision on trunk roads, vary according to local circumstances. They derive from the prevailing traffic regulation orders under the Road Traffic Regulation Act 1984 and are indicated by traffic signs and road markings in the normal way. Changes are subject to statutory procedures for consultation and public advertisement. Installation of safety fences in central reserves is not obligatory on trunk roads but there is a programme to extend safety fencing to most dual carriageways.
