Casualties are reported in many different ways in different countries. Definitions and report rates vary, which makes international comparison difficult [25]. For years, the European Commission has been striving for a harmonised definition, based on road crash casualties with MAIS3+ injuries. Quite a number of countries encounter problems in collecting the necessary data (police and hospital data) and performing the required data editing to determine the number of serious road injuries (MAIS3+). In 2014, the European Commission did give a first-time estimate of the number of serious road injuries in Europe: 135,000 [26]; for 2019, this estimate was 120,000 [27].
