ADR is the acronym given to The European Agreement Concerning the International Carriage of Dangerous Goods by Road, which was made at Geneva in 1957 by United Nations Economic Commission for Europe. Dangerous goods are materials or items with hazardous properties which, if not properly controlled present a potential hazard to human health and safety, infrastructure and/or their means of transport.
