Abstract
Although the official Belgian collision statistics reveal that road deaths from drink driving dropped by 45% in 2008 (compared to the mean figure of 1998-2000), which is 10 percentage points faster than all road deaths the same period in Belgium (-35%), drink driving accident data in Belgium remain incomplete and patchy, with breath test results available in only 60% of all crashes. Moreover, less than one percent of drivers killed in traffic are tested for alcohol. Since the official accident statistics do not allow clear conclusion, the IBSR relies on general European data to estimate that drink driving is the main contributory cause in about 25% of all lethal accidents.
