Samenvatting
De vergelijking van 2 groepen autobestuurders (één groep betrokkken bij ernstige ongevallen) gaf het volgende resultaat: This study has shown that in some significant respects the 1109 North Carolina drivers involved in fatal accidents in 1955 differed from the 1109 North Carolina drivers selected at random as a control group. 1) Drivers involved in fatal accidents performed somewhat worse than average in some phases of the original licensing procedure. 2) The data suggest rejection of the idea that drivers who become involved in fatal accidents are typical drivers who show no advance "symptoms" of the kind of driving that might eventuate in a fatal accident.
