9.—(1) Where, as respects a crossing or controlled area, the requirements of this Part as to the placing of signs and road markings to indicate the crossing or controlled area have not been complied with in every respect, the crossing or, as the case may be, the controlled area shall nevertheless be treated as complying with these Regulations if the non-compliance—
(a)is not such as materially to affect the general appearance of the crossing or the controlled area;
(b)does not, in the case of a Pelican crossing or a Puffin crossing, affect the proper operation of the vehicular and pedestrian light signals at the crossing; and
(c)does not relate to the size of the controlled area.
(2) Nothing in any other provision of these Regulations shall be taken to restrict the generality of paragraph (1).
