National Heavy Vehicle Braking Strategy – Australian Design Rule 35/06, 38/05 - Improving the Stability and Control of Heavy Vehicles

Regulation Impact Statement – Department of Infrastructure, Regional Development and Cities

On 5 June 2018, the Minister for Urban Infrastructure and Cities announced new measures to mandate Electronic Stability Control (ESC) for heavy vehicle trailers from July 2019 and for selected heavy trucks and buses from November 2020. Heavy vehicle rollover and loss of control crashes account for 22 per cent of all heavy vehicle injury crashes in Australia between 2008 and 2010.

A regulation impact statement examined 5 options to increase the fitment of ESC and Roll Stability Control (RSC) to the heavy vehicle fleet and found that the option with the highest net benefit was to mandate fitment of ESC for new prime movers and short wheel base rigid vehicles greater than 12 tonnes and new buses greater than 5 tonnes, fitment of ABS for new trailers greater than 4.5 tonnes, and fitment of RSC for new trailers greater than 10 tonnes. 

The RIS estimates that the preferred option will result in additional regulatory costs of $11.1 million per annum.
