Background: The causes of high accident rates in road traffic should be seen in the human factor (Vries et al., 2017). The driver is influenced by many different and simultaneouslyinteracting stimuli, which must be correctly perceived and analyzed in order to select the right response. Very often a person is unable to cope with a large amount of information and integrate it accurately. This leads to stress, which reduces cognitive resources and results in a loss of efficiency in various executive functions (Stephens & Fitzharris, 2016).Methods: Professional drivers (N=200), who work only in the area of Lublin City, were surveyed. For the research purpose the Polish version of Impulsiveness-Venturesomeness-Empathy Questionnaire (Eysenck & Eysenck, 2006), Questionnaire for Subjective Assessment of Work (Dudek et al, 2004) and Short Form of Five Facet Mindfulness Questionnaire (Baer, Smith, Hopkins, Krietemeyer and Toney, 2006) were used. Results: There is signifacant correlation between impulsivness, mindfulness and occupational stress perception (R=-0,323, p<0,01; R=-0,210, p<0,01; R=0,185, p<0,05). The correlation level is low so the analyzed constructs are mostly independent. What is more important the mindfulness (β=-0,168, p<0,05) is a moderator of relation between impulsiveness (β=0,130, p>0,05) and occupational stress perception (R2=0,059, p<0,01). Conclusions: The main objective has been achieved because mindfulness has an impact on the relation between personality and stress perception. It is necessary to explore the resilience factors which can be used in driver training programs to eliminate or reduce negative outcomes associated with psychological deficits.
