In the European SafetyNet project, safety performance indicators (SPIs) have been developed for 7 areas, including alcohol. The SPIs are used to indicate and compare road safety performance in different countries and years. The alcohol SPI is defined as the percentage of fatalities resulting from accidents involving at least one driver impaired by alcohol. The alcohol SPI for 26 countries varies from 4.4 % to 72.2 %. The question whether extreme values reflect the real situation or if there is a methodological explanation is studied in this report. The results indicate that there is a need to improve the data quality. Until these improvements are made, it is difficult to compare the alcohol SPI results across countries.
