Recent survey showed that many Europeans don't know that when they travel within Europe there is one emergency number (free of charge!) they can call in every country: 112 (112 day: 74% of Europeans don't know what emergency number to call when travelling in the EU. New campaign.). Only 34% of regular travellers and 26% of all Europeans are aware of that (Eurobarometer survey on 112). This is astounding, taking into account that often it is when we travel that we need emergency assistance and knowledge of that number could be more than just handy. The European Commission asked and received help of many transport companies to increase awareness of this emergency number among European travellers in 2012. Interestingly, also European countries who are not members of the EU have introduced or are introducing this number for emergencies (e.g. Turkey, Croatia).
More on this emergency number may be found on the website set up for it.
