Road performance data on 304 taxi drivers were obtained by pairsof trained observers using behavioural checklists. Drivers did not know they were being observed. Two thirds of the drivers were then asked to participate in the laboratory study in which they performed on two different driving simulators and on four perceptual-motor tests. Officially recorded accidents and violations over a 5-year period were obtained for each driver for comparison with performance data. Few of the scores from the simulators or tests were found to be significantly correlated with road performance. A number of significant relations were found between perceptual-motor test performance andsimulator performance. Although these correlations were not high, they tended to be more significant than those between performance on the two simulators.
