[Significance of psychological personality testing of motor vehicle drivers in the traffic safety system].

The study using multifactor personality questionnaire (shorter variant of MMPI) covered 619 drivers aged 20 to 59. Professional success was assessed according to occupationally important psychophysiologic parameters (OIPP) and number of committed traffic accidents (TA) in 4 groups of the drivers. Individual psychologic traits appeared to correlate with reliability criteria (OIPP and TA). Approaches evaluating the drivers' reliability should therefore consider personal features for better differentiated correction of psychophysiologic parameters. Advances in programs of traffic safety is strongly associated with complex approaches of prophylaxis that should consider significance of psychologic factor.
