The report ‘Excessive speed limit infringements’ is the result of the eight theme analysis conducted by AIB, the Danish Accident Investigation Board. The report differs from previous AIB publications by combining qualitative and quantitative measures in two independent studies, presented in two independent subsections. First, a qualitative study is presented based on interviews with motorists having been stopped by the police for exceeding speed limits by a large margin. Second, a quantitative study is presented based on a cross-analysis of data from earlier AIB road traffic accidents implying excessive speed. The accidents included were all investigated in one of the former AIB theme analyses (theme 1-7), following the standard AIB data analysis procedure. The cross-analysis does not comprise new and previously unpublished road traffic accident data. Throughout the report excessive speeding is defined as exceeding the speed limit by more than 30%. This margin is the limit set by the Danish state authorities for putting point s on the driving licence. (Author/publisher)
