Placards on Road Trains

Question: If a road train or combination vehicle (multiple trailers being pulled by one truck) is carrying dangerous goods, is it required to reproduce a dangerous goods placard at the rear of the last trailer if the last trailer does not contain dangerous goods?

Answer: No, when dangerous goods are placed in a road train, such as A, B or C train trailers, placards must only be displayed on all four sides of the trailer that actually contains the dangerous goods. Displaying a placard on the rear trailer would be considered misleading as to the presence of dangerous goods if it does not contain dangerous goods.
