In the field of highway safety considerable work has been done to develop various tests of driving ability. In this development two major problems present themselves. First, the test itself must be perfected so as to be reliable, that is, the test must give the same result when repeated. Second, the validity of the test must be determined by comparing the results of the test with actual performance. To do this a criterion of driving ability must be established. Rating of drivers from general observation does not yield satisfactory results. As an instance of this the correlation between accidents per year and a typical rating was found to be +.01 for a group of 43 bus drivers.
