231. We recommend the continued use of the word 'Slow' on the carriageway to supplement roadside warning signs and advance direction signs as appropriate.
232. We recommend that Regulations permit the Give way roadside sign (figure 8) to be supplemented by a carriageway marking where in the view of the highway authority such an advance warning is desirable. This could take the form of a hollow white inverted triangle or the words 'Give way' whichever is found by experiment to be the more effective.
233. The word 'Stop' should always be used on the carriageway to supplement the sign recommended at figure 7. The word 'Halt' (Regs. RM 30) should cease to be used.
Taxi rank (Regs. RM 9)
Look right/left (Regs. RM 16)
234. We recommend that these should continue to be used in their present form.
235. There should be greater use of direction arrows marked on the carriageway, and also of place names indicating advance destinations, and they should be set well back within lane lines so that drivers are assisted to move into the correct lane in good time before reaching a junction.
236. The words 'Keep clear' are now used with some success on the carriage way opposite junctions which tend to be blocked by traffic held up by a railway level crossing or at a junction ahead. We recommend the continued use of the words for this purpose.
237. With the increase in traffic and liability to urban congestion there is some justification for keeping spaces in front of ambulance stations, hospitals and fire stations clear of parked vehicles so that ambulances and fire appliances can move in and out; also in front of schools so that children can be clearly seen from passing vehicles. A few markings such as 'Ambulances only' and 'School entrance'' have been authorised and have proved effective . We think they should continue to be authorised where serious difficulties would be created without them but they should not be allowed to proliferate nor be permitted for the benefit of private interests.
