The drivers of forestry transport work for long periods of time, which implies an increase in fatigue and which, added to both personal and environmental factors, affect the ability to respond to immediate reactions, which can trigger unwanted driving events. Therefore, it is necessary to inquire about the personality of individuals and their relationship with the behavior they manifest in their work environment. A study was carried out in 2 companies in the forest transport sector, with the aim of analyzing the relationship between psychosocial risk factors, the level of personality traits that drivers have and their possible effect on accident rates. The sample consisted of 62 drivers, grouped into two classifications, depending on accident conditions, in accidents and not accidents. Psychosocial risk was assessed using the SUSESO/ISTAS 21 questionnaire, and specialized tests were used for personality trais, self-esteem, impulsivity, locus of control and tension; In addition, a sociodemographic record was made. The results of the psychosocial risk assessment determined that both companies were exposed to low risk. Depending on accident condition, in both groups the same level of self-esteem was obtained and the absence of stress prevailed. For the accident condition, the tendency was to manifest high levels of impulsivity; and, for the condition without accident, to present locus of external control. Significant differences were determined, according to the accident rate, only in the psychosocial risk dimension, active work and skills development. For the group with accidents, active work and skills development, it was the dimension that presented a greater number of significant correlations, both with other dimensions of psychosocial risk, as well as with perceived stress; however, in the group without accidents, the greatest number of significant correlations occurred between double presence and personality traits impulsivity, locus of control and tension.
