Abstract
The authors investigated the road offences committed by a sample of drivers to test the supposition that the less intelligent male driver would have the greatest number of convictions of a variety directly related to irresponsible driving and indirectly to road accidents. It was found that the supposition was an over-simplification as the Test did not measure performance adequately, thus penalising those who might be labelled as being intellectually retarded on the grounds of illiteracy.
