The VDAM Rule 2016 aims to set a reasonable balance between safety, productivity and use of New Zealand’s roads.
To help address the increasing freight and passenger transport tasks, the VDAM Rule allows for new gross mass limits of:
The new gross mass limits will be phased in over two stages:
Note: If you take advantage of the increased gross mass limits and travel on a road not currently accessible on the 45/46 map, you will be over the limit for that road and non-compliant.
For example, if your vehicle weighs 45 tonne and is travelling down a state highway shown on the map, you are operating legally. If you then turn onto a local road not on the map, and you have not obtained a permit for that local road, you are no longer compliant.
Please also remember that weighing tolerances have reduced so check your information and routes carefully.
The two-stage approach gives time for bridge assessments to be completed, to identify any route restrictions and bridge postings required prior to making the new limits general access at 1 December 2017.
