As early as 1935, Marbe (5) wrote that it seemed obvious there were certain human deficiencies, such as the range of attention, clumsiness, and absentmindedness which predisposed to accidents and expressed the opinion that to some extent the deficiencies making for accident proneness could be detected by tests, and persons suffering from them could be given special training or excluded in advance from dangerous trades. Lauer (4) in 193 7 observed that the ultimate method of evaluating driving ability will probably be that of identifying patterns of response which may prognosticate accident susceptibility. In 1949 Tillman and Hobbs (6) found that high and low accident groups among taxi-drivers differed markedly in their personality characteristics. In a later study they found the same differentiation among drivers in the general driving population. Eight paper-and-pencil tests were used in connection with a study of taxicab drivers by Ghiselli and Brown (3) in 1949. The battery of tests showed a validity of .59 with accident records as the criterion. Freeman (2) in 1952 found two factors of personality Dominance-Submission and Radicalism-Conservatism to be highly significant in relation to accident involvement of a group of lay drivers. The present study was made in an effort to determine the relationship between personality traits of commercial drivers as revealed by the Cattell 16 P.F. Test and accident involvement as evidenced by their accident records.
