ADR stands for “Accord Dangerous Routiers” (or “European Agreement concerning the International Carriage of Dangerous Goods by Road”). It is a treaty established by the United Nations Economic Commission for Europe (UNECE) to regulate the transport of dangerous goods by road across Europe and certain neighboring regions.
The key components of the regulations are Annexes A and B. Annex A provides definitions and guidelines for the packaging and labeling of dangerous goods, ensuring they are transported safely and clearly identified. Annex B focuses on the construction, equipment, and operation of vehicles used for transporting these goods, detailing essential safety and operational standards.
