Can popular PBS trucks enter mainstream regulations

When Australiars Performance Based Standards (PBS) Scheme commenced it was envisaged that new and improved truck and trailer configurations would emerge and that some of these would be so popular that they would become common under the Scheme. If these popular PBS configurations could somehow be added back into the mainstream mass and dimension regulations, their level of adoption by the industry and their consequent impact on the broader economy would both increase significantly. This paper examines the rise of the PBS ltruck and dogr combination, and presents a proposal for how this combination may be treated under mainstream regulations without undue compromise on the safety checks and balances that have hitherto applied to it under the PBS Scheme.
