DCAN 15: Vehicular Access Standards
Layout of Accesses for Single or Paired Dwellings

9.1 On rural roads the access layout must allow at least one vehicle to wait off the carriageway. Alternative layouts are shown in Figure 6.

9.2 Within development limits, lowering of kerbs will normally be acceptable where there is a frontage footway. Where the priority road carries more than 3000 vehicles per day, the entrance gates should be sited at least 5m from the edge of the carriageway to allow an entering vehicle to stop clear of the carriageway when the gates are closed. On other roads gates shall be sited behind the visibility splay and must be hung so that they do not open towards the carriageway or, where that is not possible, sited so that they do not open into the public road area.
9.3 The minimum width of a single access will normally be 3.2m with a maximum width of 5.0m.
9.4 The gradient of the access should not normally exceed 8% over the first 5m outside the public road boundary (see section 13.4 for accesses onto trunk roads). It is good practice to avoid excessive gradients (i.e. more than 10%) over the remainder of the access so that it may continue to be used during wintry weather.
