Abstract
Blood samples from 281 road users fatally injured in the London Area have been analysed from alcohol content. At least 20 per cent of these persons had alcohol present in their blood at the time of their accidents and 12.5 per cent had concentrations of at least 100 mg/100ml of blood. Approximately one-half of the sample were pedestrians, whose blood alcohol levels were similar to those of the other road users. Alcohol was present in the blood of 25 per cent of males but only 5 per cent of females.
