The Performance Based Standards (PBS) scheme is as a voluntary regulatory system, facilitating the integration of more productive commercial vehicles into the road network, contingent upon meeting safety and infrastructure protection standards. The latest version of the Directional Stability Under Braking (DSUB) Standard mandates adherence to the editions of ADR 35 and ADR 38.
The ATA’s submission supports the proposed amendments to the DSUB standard while emphasising the need for clarity in terminology. The incorporation of the WA Performance Based Standards (PBS) Scheme – Road Train TEBS Voltage Test Procedure provides a practical solution to define and assess the term ‘adequate’ in the context of power supply for Trailer Electronic Braking Systems (TEBS), contributing to the overall enhancement of road safety standards.
