6. Schedule 3 - Upright signs that indicate regulatory requirements for moving traffic
The new structure
6.1
Schedule 3 prescribes regulatory roundels and follows a similar format to Schedule 2. However, unlike warning triangles, roundel sizes remain individually prescribed. The full size range for sub-plate x-heights applies in all instances. Advice on appropriate uses of x-heights is given in Chapter 3 of the Traffic Signs Manual. The new structure for regulatory roundels is set out in Table 6.1:
| Part 1 | Introduces the tabular structure in Part 2 which prescribes all regulatory roundels and associated sub-plates. The use of the tabular structure is set out, whereby each itemised row contains the component parts that may be used in combination as appropriate. It is specified that component signing elements may only be derived from a single itemised row - a 'mix and match' of component elements from multiple rows is not permitted. |
| Part 2 | Provides the starting point for regulatory roundels and sub-plates with a 'blank canvas' that prescribes roundel and sub-plate x-heights, The desired sign and associated sub-plate legends (by reference to Part 3) are shown in itemised rows, as set out below, with cross references to the applicable provisions and directions. These are arrived at by working along any given row taking account of the cross references to associated plate legends and the applicable sign specific provisions and directions. |
| Column 1 - Table Item number. | |
| Column 2 - Sign diagram number and sign description. | |
| Column 3 - Sign illustration. | |
| Column 4 - Contains prescribed roundel sizes. | |
| Column 5 - Cross refers to associated plate legends in Part 3. See below. | |
| Column 6 - Cross refers to sign specific provisions in Part 4. See below. | |
| Column 7 - Cross refers to Schedule 3 General Directions. See below. | |
| Part 3 | Sets out applicable itemised supplementary plate legends. |
| Part 4 | Sets out sign specific provisions. |
| Part 5 Schedule 3 General Directions |
Sets out sign specific directions. |
