7.12 Signs for permit parking may include permit identifiers as shown in diagram 660.3, and may use numerals in addition to letters (e.g. A1, A2 etc.). Identifiers might be necessary where schemes for different permit holders are in operation in adjacent areas. Each scheme would have its own identifier (e.g. "A" for one scheme and "B" for another) shown on the respective signs. To provide flexibility for residents, permit schemes may overlap so that some roads are common to two or more schemes. The signs on these roads would include the permit identifiers for each scheme as shown in diagram 660.3. Permit identifiers are often used in conjunction with a controlled parking zone (see section 12). For a stand-alone scheme, permit identifiers are not normally necessary. Identifiers are not used when diagram 660 is varied to "Card holders only" or to "Large or slow vehicles only".
7.13 Where permit identifiers are used, the letters and numerals must be from the Transport alphabet; there is no provision in regulation 13(7) for a different lettering style. The characters and the patch on which they are placed may be varied in size and may be in any contrasting colours, although the recommended size is as dimensioned on working drawing P 660.3 (see para 1.9). The recommended colours are white characters on black patches as shown in diagram 660.3.
7.14 Signs to diagrams 660 and 660.3 may be varied to include times of operation; examples are shown in figure 7-2. Outside those times any vehicle may park in the bay unless there are signs and markings to indicate otherwise.
7.15 Where parking in an entire road is reserved solely for permit holders and where no other parking or loading activities are permitted, it might be possible to provide signs at the entrance to the road and dispense with signs and bay markings within the road itself. Figure 7-3 shows a typical entry sign. It should be noted that such signs are not prescribed by the Regulations and will require authorisation (see para 2.1). Design details are provided on working drawing NP 434, available from the Department on request. Many roads will not be suitable for this type of signing and any proposed scheme should be discussed with the Department at an early stage. The most likely candidates would be a cul-de-sac or a small network of roads with little or no through traffic. This type of signing might be appropriate in an environmentally sensitive area, or near a large sports stadium where parking restrictions are required only on certain days of the year (see para 7.41). The entry signs may be supplemented by signs to diagram 660 or 660.3, used as reminders in the individual streets. In this case a special direction should be sought from the Department (see para 2.1) to allow the signs to be used without bay markings. Any part of a road may include a prohibition of waiting (which would apply equally to permit holders) and be signed and marked as described in section 6. Signs indicating the end of the permit holder parking area will be needed, unless it is a cul-de-sac, and again these will require authorisation.
