T1A or TW01 Temporary Warning Road Works Roll Up Road Signs, referred to as a W1-1 Sign in the TCD Rule, are made of Flexi-lite retro-reflective roll up material and used at all attended work sites or unattended work sites where there are hazards within 5m of the edge of the road. The TW-1 Temporary Traffic Sign can be used on Level One New Zealand Roads for Temporary Traffic Management (TTM) and is in the Waka Kotahi Code of Practice (CoPTTM).
