TW-19 traffic direction signs may only be erected by employees of the controlling authority, or with the permission of the controlling authority by contractors or other authorised persons, to indicate the end of a section of road that has been signed with TW - 2.1 FLOODING signs.

The signs shall be removed along w ith the TW - 21 advance warning signs as soon as the surface flooding is no longer a hazard.

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 - 19 signs should be erected approximately 20 m past flooded section of road and 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.
