New Road Layout Temporary Warning Sign

Policy

A TW - 2.11 sign combination consists of a TW - 2 OTHER HAZARD sign and a supplementary sign NEW ROAD LAYOUT.

TW - 2.11 advance warning signs may only be erected by employees of the controlling authority, or with permission of the controlling authority by contractors or other authorised persons, when a section of road alignment or an existing intersection that has been altered by road works is first opened to traffic. The signs should remain in place for at least two weeks after the opening of the new alignment.

Signs should be fitted to white painted, plain galvanised steel or plain aluminium stands. Under weather conditions likely to be experienced on all but very rare occasions the stands must be stable when:

Location

Normally, TW - 2.11 signs should be erected clear of the traffic lanes. Where this is not practicable they shall be located so as to be clearly visible to approaching drivers and not present an obstruction to traffic.

The NZTA CODE OF PRACTICE FOR TEMPORARY TRAFFIC MANAGEMENT specifies location and layout requirements for Temporary Warning signs. Special attention must be given to ensuring that the minimum clear visibility and spacing distances between the advance sign and the start of the road works site are achieved.
