12.16 Waiting prohibitions sometimes apply only to goods or commercial vehicles. Where the prohibition shown applies only to goods vehicles, the lorry symbol on working drawing S 32 is placed alongside the "no waiting" roundel. A lorry together with a bus prohibition applies to commercial vehicles. Where the prohibition applies to public service vehicles only, the bus symbol alone is used with the "no waiting" roundel. Typical examples are shown in figure 12-7.
12.17 In some cases, it may be possible to reduce the sign height by placing the "no waiting" roundel to the side of the time period (see diagrams 639.1B and 640). Design details are shown in figure 12-8.
MODEL LAYOUTS FOR LIMITED WAITING TIME PLATES
12.18 Limited waiting time plates use the "P" parking symbol shown on working drawing S 43. The symbol (working drawing S 25) denotes that the size is 20 sw square. Figure 12-9 sets out the basic model for the sign design which may be combined with waiting prohibition plates as shown in diagram 639.1B. The maximum duration that parking is permitted, or the period during which a return is prohibited may be shown as hours or minutes: "minutes" may be abbreviated to "mins"; "hours" will generally be shown in full. Reference should be made to the working drawings for the shared parking bay signs shown in diagrams 660.6 and 660.7.
