The following description was taken from Transport Industry Safety Group: Truck Emergency Breakdown and Roadside Safety (TEBARS) :

The issue of safety around incapacitated trucks on the roadside is a significant safety issue confronting the transport industry along with the wider community. The aim of this guide is to share guidance in order to eliminate or reduce the potential for injuries where vehicle and people interaction occurs when attending to a broken down truck on the roadside up to the point of requiring towing.

This guidance material has been developed by industry to assist employers, drivers and mechanical service providers to implement effective controls to prevent drivers and other people being injured during the repair of broken down trucks by the roadside. It reflects the outcomes of engagement within workplaces across the supply chain in identifying the ‘do’s’ and ‘do not’s’ of effective separation of people and passing vehicles.
