Australian Dangerous Goods Code Edition 7.8 (Consignor and Transport Duties) 5.3.6.2: Combination vehicles: front and rear placards for the aggregate load, side placards for each unit with its own placard load

What does 5.3.6.2 require?

Where the aggregate dangerous goods across all units of a combination road vehicle form a placard load, the front and rear placards are determined from the aggregate load, and each trailer or rigid vehicle that on its own carries a placard load is placarded on both sides for the goods on that unit, including class, division or mixed class labels and emergency information panels where the unit carries bulk containers, tanks or placardable units.
