Another accident related to this typology was the one of Lorca (Murcia). The accident took place on the 20th of October 2011, when a tank truck loaded with 46 m3 of natural gas crashed with another truck that was stopped in the motorway hard shoulder. As a consequence the tank caught fire and later on it exploded, orig- inating a fire which spread around. The truck driver died (Bonilla, Belmonte, & Marín, 2012). Only 7 days later, a similar accident took place in Ribarroja (Valencia, Spain), but luckily without human losses.
