The future HVNL should encourage the fleet introduction and use of vehicles that perform to higher safety standards and deliver productivity benefits.

Chapter 10 of the RIS explains the options for reforming vehicle design under the future HVNL.

Summary of problems and options

Improving the timeliness and efficiency of the PBS process


There are three key issues with current PBS processes.

  1. The multi-step PBS approval process imposes high compliance costs – both in terms of dollars and time – on those seeking PBS vehicle approval.
  2. There is still a high degree of regulatory uncertainty regarding the ability to operate PBS approved heavy vehicles because vehicle approval does not guarantee access.
  3. An entire PBS fleet may be under a single access permit. Where the fleet is transferred then the access permit can be transferred without road manager consent.

Improving the flexibility and adaptability of the PBS


The PBS scheme has not kept pace with current international standards, approved vehicles must still comply with smaller width dimension limits than permitted by international standards, limiting the use of safety equipment designed for these wider vehicles. In Australia width is limited to 2.50m, while in the USA this is 2.60m and in Europe maximum vehicle width is 2.55m for general freight vehicles and 2.60m for refrigerated trucks and trailers.
