Specifies the traffic control devices to be used to warn, instruct and guide road users in the safe negotiation of work sites on roads, including unsealed roads, footpaths, shared paths and bicycle paths adjacent to the roadway together with requirements for maintaining a safe workplace for workers on site. It is applicable to traffic guidance schemes for road and bridge construction and maintenance sites, and for works associated with other public utilities and services which cause interference or obstruction to the normal use of a road.

This Standard specifies the traffic control devices to be used to warn, instruct and guide road users in the safe negotiation of work sites on roads including unsealed roads together with footpaths, shared paths and bicycle paths adjacent to the roadway. It is applicable to traffic guidance schemes for road and bridge construction and maintenance sites, and for works associated with other public utilities and services which cause interference or obstruction to the normal use of a road by any road user. It also provides guidance for the planning, design, installation and operation of such traffic guidance schemes together with requirements for maintaining a safe workplace for workers on site.NOTES: 1 Detailed specifications for the design and manufacture of the signs used are given in AS 1743.2 This Standard is intended for use in conjunction with the various State and Commonwealth regulations relating to roadworks.
