Abstract

Details are given of two general procedures used to segregate accident prone drivers: (1) the examination method. In its direct form it requires each driver to operate a vehicle under the obseration of a trained examiner; in its indirect form it requires each driver to undergo a series of performance tests of attention, motor skills and information; (2) the biographical method in which as many data as possible on the personal history of each driver are collected. A bibliographic study is presented of the applications of the two methods and of their claims to validity for predicting accident rates. Attention is drawn to the relation between age and accident rate. The reliability and validity of the tests are investigated.
