Change to braking standards for heavy vehicle trailers

02 Jul 2014

Following the Australian Government initiative made earlier this year, a change to safety standards for heavy trailers will be adopted in South Australia from 1 July 2014.

The new safety standard requires Antilock Braking Systems (ABS) or load proportioning brake systems to be installed on new heavy trailers.

The requirement for ABS or load proportioning brake systems on heavy trailers comes into force from 1 July 2014 for brand new model trailers and 1 January 2015 for all new trailers, consistent with the requirement for heavy trucks and buses.

The Department of Planning, Transport and Infrastructure (DPTI) Executive Director of Road Safety, Julie Holmes said that the new rules are expected to save over 50 lives on Australian roads over 30 years.

“This move will bring more modern and safer braking systems into the Australian heavy vehicle fleet.”

“ABS or load proportioning brake systems can greatly improve heavy vehicle stability in emergency situations and in instances of wheel lock up”, she said.

The mandating of ABS or load proportioning brake systems on all new heavy vehicles and trailers represents the completion of the first phase of the National Heavy Vehicle Braking Strategy.

DPTI will continue to work with industry in developing a code of practice so that operators can optimise the performance of different braking technologies when combining trucks and trailers together.
