Development of a short test for accident proneness.

In developing the Accident Proneness Prediction Test to measure motor control skills related to safety aptitudes subjects were instructed to draw on a sheet of paper as many circles as possible within a limited amount of time. The responses were scored in terms of the speed and quality (irregularities) of the produced circles. Although 103 accident-prone drivers produced more circles than the 178 good drivers, the quality of performance of the accident-prone drivers was poorer than that of the good drivers. Based on this validity study, we proposed these predictive criteria for further testing of accident proneness.
