International Carriage of Dangerous Goods by Road (ADR)
In Europe the International Carriage of Dangerous Goods by Road is governed by the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR). The purpose of the Agreement is to ensure that dangerous goods can travel internationally by road without hindrance provided that the goods are packed and labelled in accordance with the provisions of the Agreement and that the vehicles used comply with technical requirements set down in the Agreement. Tank vehicles, tank containers and demountable tanks must undergo a technical inspection in their country of origin.
