2.—(1) When reserved for disabled badge holders at certain times (whether or not also reserved for other users)—

(a) the length of the bay must be at least 6600 mm; and

(b) the width of the bay must be at least 2700 mm (or 3000 mm when placed in the centre of the carriageway) except in a case where, on account of the nature of traffic using the road, the overall width of the carriageway is insufficient to accommodate a bay of that width.

(2) The marks and gaps forming the boundary of the bay may—

(a) vary in number and length; or

(b) be replaced by a continuous white line.

(3) The bay may be varied to contrast, in pattern or colour, from the surrounding parts of the road and any adjoining bays, in which case the marking may be omitted.

(4) The bay may be divided into individual spaces by—

(a) the application of a white line marking (either broken or continuous), with a minimum width of 50 mm; or

(b) contrasting pattern or colour.

(5) If the individual spaces are parallel to the edge of the carriageway, the length of each space must be not less than—

(a) 6600 mm in the case of a space reserved for disabled badge holders; or

(b) 4500 mm in any other case.

(6) If the individual spaces are not parallel to the edge of the carriageway—

(a) the length of the largest rectangle that could be accommodated wholly within the space in question must be not less than 4200 mm;

(b) the width of each space must be—

(i) not less than 3600 mm in the case of a space reserved for disabled badge holders; or

(ii) not less than 2000 mm in any other case, and

(c) the spaces may be inclined at any angle to the edge of the carriageway to form an overall parking bay in echelon pattern, the boundary of which, furthest from the edge of the carriageway, may be parallel to the carriageway.
