ATA, ALRTA call for mandatory stability control

Trucking bodies present technical recommendations to government


Mandatory stability control technology in new trucks and trailers can improve road safety, the Australian Trucking Association (ATA) and the Australian Livestock and Rural Transporters Association (ALRTA) assert.

The road transport bodies have presented their recommendations to the federal government to mandate this technology and are calling for a mandatory implementation across the trucking sector.

ATA chair Geoff Crouch and ALRTA president David Smith say this technology can help prevent truck rollovers by detecting a possibility of such an event and as a result initiate braking.

Speaking on behalf of rural transporters, Smith says stability control technology can help even the most experienced drivers.

“For us, adverse conditions are an everyday occurrence,” he says.

“Our gear cops an absolute pounding from rutted roads, stones and sticks along with the dust that gets into absolutely everything.

“While running costs are always higher in these environments, there are still net benefits for operators who install the latest generation of stability control systems.

“Modern stability control systems can react far quicker than even the most experienced driver and most operators would be surprised to learn just how close they have come to a rollover.” 

Both ATA and ALRTA are confident that the technology will work across Australia’s harsh conditions.

“Notably, we consider that all new prime movers must be required to supply 24V to their trailers,” Crouch says.

“There is no international standard for multivolt stability control plugs and sockets.

“For a stability control requirement to work, Australia has to standardise on one voltage, 24V is the way to go for performance reasons.

“It’s also needed to support evolving technologies like autonomous braking.”

Converter dollies should be excluded from the mandatory stability control requirement, and that drivers should be able to turn off stability control at low speed.

“Considering the type of roads some trucks have to cover, an option to temporarily disable the system to deal with difficult situations at low speed is a must,” Smith says.

ATA and ALRTA’s technical recommendations on stability control:

  1. Stability control must be mandatory for all new trucks and new trailer types except converter dollies.
  2. Converter dollies must be exempt from the requirement to fit load sensing, ABS or stability control, similar to the current exemption in ADR38/04.
  3. The requirement that converter dollies have ‘through’ wiring must be retained.
  4. ADR35 and ADR38 must include a provision for an off-switch so that stability control can be temporarily disabled. Stability control should automatically re-engage at key on or at speeds above 40 km/h.
  5. All new trucks must be required to supply 24V to trailers. This should not be taken as preventing trucks from additionally supplying 12V or any other voltage.
