5. Schedule 2 - Signs that warn of hazards and signs for bridges and other structures
The new structure
5.1
The new structure in Schedule 2 introduces a blank template for warning sign combinations, together with the permitted size range for triangles and supplementary plate x-heights. This provides the starting point from which warning signs are created from component elements.
5.2
The subsequent Parts contain the component elements, with each having its own Table item reference. By navigating along an itemised row, the reader is guided through the applicable permitted variants and regulatory requirements to arrive at the complete signing combination.
5.3
The new structure for warning signing is set out in Table 5.1.
Table 5.1 Signs that warn of hazards and signs for bridges and other structures
| Part 1 | Introduces the tabular structure in Part 2 which prescribes all permanent warning signs and 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. These are arrived at by working along any given row following the permitted variants and cross references both to other optional supplementary signs (where appropriate) and the applicable sign specific provisions and directions. 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 warning sign and sub-plate assembly with a 'blank canvas' that prescribes the triangle size range and plate x-heights, The desired sign and associated sub-plate legends are shown in itemised rows, as set out below, with cross references to the applicable sign specific provisions and directions. Cross references are provided to optional supplementary signs that may be placed in combination with either a triangle alone, or a triangle and plate. |
| Column 1 - Table Item number. | |
| Column 2 - Sign diagram number and sign description. | |
| Column 3 - Illustration of permitted triangular sign variations | |
| Column 4 - Permitted plate legends (unless specified by a reference in column 7 to the Schedule 2 General Directions, the plate is optional) |
