6.8 Where the "no waiting at any time" prohibition applies to a period of less than four consecutive months in the year or less than seven days a week, the sign to diagram 639 is used. This is varied to "At any time", with the addition of the period or days of the week as appropriate. Diagram 639 is used with the single yellow line (diagram 1017) and never with the double yellow line (diagram 1018.1). Where there is also a loading prohibition, the combined sign shown in diagram 640 is used, varied as appropriate. The corresponding road markings will be the single yellow line (diagram 1017) and the single kerb mark (diagram 1019). Double kerb marks (diagram 1020.1) would not normally be used because the loading prohibition is unlikely to apply for 24 hours each day and for a period of at least four consecutive months, as this would be a longer period than that for the waiting prohibition.
