The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Fatigue Safety Performance Indicator (SPI) Report which focuses on the percentage of drivers driving non-fatigued. This report aims to give insight into the differences between groups of countries regarding their road user behaviour or attitude. According to this report, the mean percentage of self-reported fatigued driving (during the previous 30 days) in Europe is 23%. link pdf5
