If you use these Transport Agency-approved 'pro-forma’ (approved non-standard) vehicle combination designs when applying for a high productivity motor vehicle (HPMV) permit , it will make the approval process simpler.
If you want to build or operate a pro-forma vehicle combination that is identified below, you will need to apply for a permit. The approval will be granted and there will not be an expiry date on the permit.
Each individual vehicle in the overlength HPMV combination must in itself meet the dimensional requirements of the Land Transport Rule: Vehicle Dimensions and Mass 2016 unless specified otherwise.
Some other general conditions will also be required. The vehicle must:
meet the dimension thresholds provided on the Transport Agency pro-forma design
have an 'H' sign at front and rear of the vehicle combination that meets the specifications in the Land Transport Rule: Vehicle Dimensions and Mass 2016 – this must be displayed at all times while you are operating under the permit
not operate on any road with a prescribed length restriction if the vehicle exceeds that restriction
have lights at the rear of the combination – these must be of the light emitting diode (LED) type to address voltage drop
have repeater side indicator lights placed approx midway along the side of the trailer
only have original truck manufacturer approved modifications made to the truck frontal protection area
have conspicuity tape in red/ white meeting DOT C-3 that outlines the shape of the vehicle from both sides and rear, or LED side marker lamps or reflectors fitted at a maximum of 2-metre intervals along the side of the vehicle as close as practical to the load bed
have roll stability control (RSC) – all trailers must have RSC fitted and active.
Print off the applicable vehicle design below, complete your actual vehicle dimensions and include this with your HPMV application.
If you want to use a longer vehicle that is not a pro-forma design, then the Transport Agency can approve the dimensional variation. However, this will be route restricted and you will need to get permission to operate from each local road controlling authority affected.
The process for the Transport Agency-approval of a pro-forma design is for an industry group to agree a productive design that suits them and then have a report prepared by an engineering consultancy with respect to both high-speed stability and low-speed manoeuvring. The Transport Agency will then review the design and report, and if acceptable will approve the new pro-forma and update this web page.
