Traffic control devices manual

The planned structure of the Traffic control devices manual comprises 16 documents (three specifications, 10 parts, an addendum, a glossary and a list of references) and is shown in the table below.

Each part will be developed under the guidance of a working group of practitioners experienced in, and having specific knowledge about, the subject. The practitioners will also be representative of the intended users of the documents. Interested practitioners and affected organisations will be given the opportunity to comment on drafts and have their input incorporated appropriately in the final document.

The Traffic control devices manual will be published electronically only.

The following table shows the complete list of parts of the manual. These will be added to this website as soon as they become available.

Relationships with other documents

The Traffic control devices manual will support and reference:

  • New Zealand legislation and, in particular, the Land Transport Act 1998 and rules made pursuant to that act, including the Land Transport (Road User) Rule, the Land Transport Rule: Traffic Control Devices and the Land Transport Rule: Setting of Speed Limits
  • general polices contained in Austroads Guides (in particular, the Guides to Traffic Management, Traffic Design and Road Safety) by providing detailed guidance to meet specific requirements of New Zealand law and practices
  • New Zealand and, as appropriate, Australian standards
  • codes of practice, guidelines and published standards of various authorities.
  • the Speed management guide – a national framework that helps road controlling authorities make informed, accurate and consistent speed management decisions for their communities.

Each part will attempt to provide a broad coverage of the subject but avoid duplicating major elements of referenced documents, preferring to direct readers to the source.

The Traffic control devices manual will, on completion, replace the joint Transit New Zealand and Land Transport NZ publication Manual of traffic signs and markings (MOTSAM). However MOTSAM Part 1 Traffic signs and Part II Markings will continue to be available until their contents have been replaced. Recently approved traffic signs are notified in Traffic notes until these signs have been incorporated into the appropriate part of the TCD manual.
