is, to the extent of putting down or taking up a passenger. This exception is not, however, made in clearway Orders on rural roads save for buses, and in peak-hour clearways on urban roads it extends only to buses and taxis. Owing to the need felt increasingly on the Continent to differentiate between the signs indicating 'No waiting' and 'No stopping', the Economic Commission for Europe Working Party concerned with traffic signs has recently recommended that a sign with crossing transverse red bars (figure 26) as distinct from a single transverse red bar (figure 25) be used to indicate that stopping (which includes loading and unloading) is prohibited.
85. We recommend:—
(i) That the newly introduced Protocol sign at figure 26 be adopted to indicate 'No stopping'. It therefore becomes appropriate for use on clearways, since (with the exceptions referred to above) stopping, and not only waiting, is prohibited on clearways. We recommend that it be adopted instead of our present Clearway signs which are not known abroad. The size of this new No stopping sign should vary with vehicle speeds and the end of a clearway should be indicated by the same sign with the plate at figure 26a beneath it. The detailed conditions on a peak-hour clearway should be indicated on a plate beneath the sign.
The same No stopping sign could potentially be used on short lengths of street, for instance, on corners in urban areas, where all stopping is prohibited, but in the interests of not increasing the number of roadside signs we recommend that some form of yellow carriageway or kerb marking be used alone to indicate this.
(ii) That the Protocol sign at figure 25 should be used to indicate 'No waiting' and that the periods during which waiting is prohibited be indicated by black lower-case letters on a white plate beneath it (figure 25a). If no times or days are given the prohibition will be continuous. If prohibitions are indicated from Mondays to Fridays it follows that no prohibitions exist on Saturdays and Sundays.
(iii) If any limitation is imposed upon loading and unloading it should be indicated by details given in black lower-case letters on a yellow plate (figures 25b and 25c). Thus hauliers and others delivering or collecting goods will be able to see immediately and from some distance whether or not any restrictions exist upon loading and unloading.
(iv) Where waiting is restricted to a limited period this period should be shown by white lower-case letters on a blue plate (figure 25d) below the No waiting sign at figure 25. White on blue is chosen for this permissive message to distinguish it from the restrictive message indicated by black on white or yellow.
If more than one of these three messages is required they should be carried on a single plate (figure 25b).
(v) We have considered whether times on plates should be expressed in terms of the 24-hour clock which would save space but we think that this is premature.
(vi) Where this restriction of waiting time is in force on different sides of the street on alternate days the change should be indicated by a flap to the rectangular plate analagous to the flap device now used on the No waiting and Limited waiting signs themselves. These flaps should be secured in
