Unsuitable for Motor Vehicles
132. We are of opinion that where a road is unsuitable for a particular type of vehicle, action should be taken by statutory Order to prohibit the use of the road by such vehicles. There are cases, however, where by reason of conditions other than dangerous conditions a sign “Unsuitable for Motor Vehicles” (diagram 108) could usefully be employed, and we recommend its special authorisation in these cases.
Cyclists Only
133. Diagram 109 shows a sign authorised for use at the entrances to cycle tracks. We have included it in the class of informative signs since it does not give effect to any statutory Order or Regulation. We recommend its continued use subject to the symbol and letters being in black on a white ground instead of in white on a blue ground as at present.
Cyclists and Service Road
134. We recommend that in the sign “Cyclists and Service Road” shown in diagram 110, the letters should be in black on a white ground instead of in white on a blue ground as at present.
Dual Carriageway Ahead
135. Diagram 111 shows a sign which we recommend should be used where it 1s necessary, in accordance with the Regulations recommended in paragraph 30, to inform drivers that they are approaching a dual carriageway road on which the direction of flow of traffic is governed by Regulations, and where the words “dual carriageway” do not appear on any other sign (whether direction or mandatory) at the junction.
One Way Street
136. We do not recommend any change in the sign “One Way Street” shown in diagram 112. It is intended for the information of pedestrians.
Bridge Ahead, Maximum Weight Tons
137. When an Order is made prohibiting vehicles in excess of a certain weight from crossing a bridge, the prohibitory signs giving effect to the Order are erected at the bridge. It is frequently desirable to provide in addition an advance sign informing drivers of the restriction, and erected on the route to the bridge at a road junction where an alternative route available to traffic covered by the Order branches off. Diagram 113 shows a typical sign of this character. Signs of this type are specially authorised in individual cases. We recommend continued use of these signs, and see no objection to the inclusion, in appropriate cases, of information about the alternative route available.
Passing Place
138. We have already recommended, in paragraph 52, the general authorisation of a sign “Single Track Road with Passing Places.” The sign shown in diagram 114 is recommended for marking these passing places. It is similar to the existing sign authorised for this purpose with the addition of the words “Passing Place” to make its purpose more clear.
Pass Either Side
139. The sign shown in diagram 115 is recommended for use on central islands and other obstructions in the carriageway of streets and roads subject to a one-way traffic Order.
