Background, purpose. Lithuania is named as a leader among other countries in European Union for the number of death on road accidents. Risky behavior of a driver is identified as the main reason for such situation. In this context appropriate and reliable evaluation of risky driving is very important. Practitioners and researchers are lacking for broadly applicable complex instruments that would also be reliable and valid to assess risky driving. Therefore, the main aim of the research was to evaluate psychometric properties (reliability and validity) of Driver behavior questionnaire Lithuanian version. Method. The research involved three groups of participants (young, professional drivers and mixed by age group). The whole sample consisted of 942 drivers. Respondents filled up a questionnaire consisting of Driver behavior questionnaire (Parker et al., 1995), exact questions about remembered accidents on road. 40 participants from young drivers’ group tried driving simulator. Some other questionnaires were added in order to evaluate drivers’ personality traits, attitudes towards risky driving. Results. The research results showed that Driver behavior questionnaire was highly reliable. Besides, stability of the test-retest results was an important feature of this instrument. Exploratory, confirmatory factor and correlation analysis suggested two factor solution for this instrument. Content and criterion validity was confirmed by statistically significant relations between risky driving and aggressiveness, neuroticism, risky attitudes, remembered accidents on road (positive correlations), conscientiousness (negative correlations). Conclusions. In summary, Driving behavior questionnaire Lithuanian version can be labeled as an instrument with appropriate psychometric properties for future research in risky driving field and for application in practice.
