Call for trailer and truck stability mandate

  • Posted on Thursday 10th, August 2017.

The Australian Trucking Association (ATA) and the Australian Livestock and Rural Transporters Association (ALRTA) have called for the Australian Government to mandate stability control technology for trailers and trucks.

ATA Chair, Geoff Crouch, said electronic stability control is a vehicle safety system that monitors the stability and sideways acceleration of a heavy-vehicle, and triggers the brake when the system detects a rollover threat.

“It's a vital safety technology and should be mandatory for new trucks and trailers,” said Crouch.

President of the Livestock and Rural Transporters Association of South Australia, David Smith, said that mandatory stability control was in the best interests of the trucking industry, including rural operators.

“For us, adverse conditions are an everyday occurrence. Our gear cops an absolute pounding from rutted roads, stones and sticks along with the dust that gets into absolutely everything,” said Smith.

“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.”

The associations have put forward a package of technical recommendations to the Australian Government to ensure 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,” said Crouch.

“There is no international standard for multi-volt 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.”

Smith said 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,” said Smith.
