The National Heavy Vehicle Regulator (NHVR) has expanded the performance-based standards (PBS) pre-advised design approvals in its latest update.

From April 1, 2019, the PBS pre-advised design approval process includes qualifying B-double combinations up to 30m.

The scope of pre-advised specifications for truck and 3- or 4-axle dog and prime mover and semi-trailer combinations has also been broadened to include Level 2.

NHVR chief engineer Les Bruzsa says the pre-advised process is improving processing times.

"Since the commencement of the pre-advised design approval trial in March 2017, application processing times for applicable vehicle types have reduced on average from four weeks to three business days," Bruzsa says.

"To date, most major combination designs have been pre-advised and it is estimated that 90 per cent of all PBS design applications will qualify for approval under the simplified pre-advised design approval process."
