 The advantage of an HQDC over a motorway in this regard is that a simpler planning permission process is used, rather than the more complex Motorway Scheme process used to create a motorway.However the problem of using the normal planning process is that in theory planning permission could be granted for a direct access for a home or business onto the HQDC; although such direct accesses are now discouraged under public policy there is no legal impediment.Motorways, by contrast, may only have accesses at junctions and service areas.
