pedestrians as well as vehicular traffic we suggest that the words ' Cul-de- sac' be included in the street name plate. Where it is considered essential to give advance notice of a ' no through road' we recommend that the sign at figure 102 be used on the main road, with appropriate variations to the symbol so as to show the road layout; we urge that sparing use be made of this sign to avoid unnecessary clutter.
164. There is no Protocol sign for this and we recommend that words continue to be used but in the form shown in figure 103.
165. We recommend the sign at figure 99 (see paragraph 59).
166. We recommend that the same words be used but in the form shown at figure 104.
167. Since we have been unable to devise a reasonable symbol for this we recommend that words continue to be used as illustrated at figure 105.
168. Words seem quite unnecessary here and we recommend the use of a mandatory arrow as shown at figure 14. This sign should be placed at the point of the dual-carriageway's central reservation and supplemented by a No entry sign (figure 15) wherever there is a danger of drivers attempting to enter the wrong carriageway.
169. As this should be a general rule for all driving we hope that this sign can soon cease to be used . But so long as it is required we see no alternative to its being expressed in words, which should be in white capital letters on a blue ground.
3 miles ahead. Weight limit 10 tons (Regs. 412)
270 yards ahead. Prohibited all vehicles unless requiring access to premises or land adjoining the road (Regs. 412A)
130 yards ahead. No right turn (Regs. 413)
170. We considered whether for these signs Protocol symbols could be used in conjunction with rectangular plates beneath indicating the distance ahead at which the prohibitory symbols apply. But we concluded that for the sake of clarity prohibitory symbols should not be used except at the point at which they apply and where penalties can be imposed for ignoring them. We therefore think that advance notice of these prohibitions must be given in words but that the message should be kept as short and simple as possible. An example of this type of sign is given at figure 105.
