The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Alcohol and Drugs Thematic Report which emphasizes that impairment due to alcohol and/or drugs is a major cause of motor vehicle crashes worldwide. It has been estimated that 1.5 to 2% of kilometres travelled in the EU are driven with an illegal blood alcohol concentration. Furthermore, around 25% of all road deaths in the EU are alcohol-related. Moreover,  Recent roadside surveys among randomly stopped drivers in EU-countries show alcohol prevalence rates between 0.3- 2.7% and drug prevalence rates between 6.0 – 11%.
