Australian Dangerous Goods Code Edition 7.8 (Consignor and Transport Duties) 13.1.2: Breakdowns: hazard or parking lights on and warning triangles placed at the prescribed distances

What does 13.1.2 require?

When a dangerous goods vehicle breaks down on a road, or stops in a way that endangers traffic, other road users are alerted by leaving the hazard lights on (or the parking lights if there are none) while the battery remains connected, and by placing portable warning triangles: on roads with a speed limit of 80 km/h or more, one 200 to 250 metres behind, one between it and the vehicle on one-way or divided roads or one 200 to 250 metres in front on other roads, and one beside the vehicle on the traffic side; on slower roads the same pattern at 50 to 150 metres. Compliance with the Australian Road Rules on warning triangles counts as compliance with the Code.
