Both RTF and TTMF raised questions over the HPMV proforma truck trailer diagrams.

As both organisations pointed out some, of the HPMV drawings/schematic diagrams had an incorrect dimension on them. This has now been corrected by Waka Kotahi NZ Transport Agency and the correction can be sourced through the following link.

The proforma for truck and long drawbar has now been corrected on the website to give the 11400 mm max limit:

Thank you to the members that brought the original oversight to our attention.
