We analyzed their involvement in accidents in relation to several indicators suggested by the literature, including the temporal dimension of those bus drivers, as expressed in Zimbardo's Time Perspective Inventory (ZTPI), for previous studies have shown that people more present time oriented revealed greater tendency to engage in risk driving. A questionnaire was applied to 457 bus drivers of the city of Natal, RN, Brazil, with questions about participants socio-demographic information, their professional performance and items on time perspective, presented in a five points Likert type scale. Among the indicators analyzed, the best predictors of traffic accidents were: worried about not being on schedule, family problems, and falling asleep; to work overtime, passengers complaints, work while on vacations and medical leaves. In regard to drivers' time perspective, the sub-scale of "combined present" showed a positive relationship with involvement in transit accidents, while the future scale a negative one, in both cases in accordance with the expect direction, even though the effects have not been statistically significant. The selected predictive variable indicate that traffic accidents are mainly associated to situational factors, that could be prevented through the betterment of work conditions of the bus drivers and other organizational and public policies, since transit accidents should be part of initiatives in the areas of health and safety / O prop?sito deste estudo foi investigar indicadores do envolvimento de motoristas de ?nibus urbano em acidentes de tr?nsito. Relacionamos esse envolvimento em acidentes com v?rios dos indicadores apontados pela literatura da ?rea, incluindo a dimens?o de tempo daqueles motoristas, tal como expressa no Invent?rio Zimbardo de Perspectiva Temporal (IZPT), pois estudos anteriores constataram que pessoas mais ligadas ao presente relatavam maior propens?o de risco ao dirigir. Um question?rio foi aplicado a 457 motoristas de ?nibus de Natal, contendo perguntas sobre atua??o profissional, caracter?sticas sociodemogr?ficas dos participantes e os itens de perspectiva temporal, respondidos em escala de cinco pontos, tipo Likert. Dentre os indicadores investigados, verificamos que os melhores preditores relativos aos acidentes de tr?nsito foram: preocupar-se com dirigir atrasado, com problemas familiares e com o pr?prio sono; fazer horas extras; reclama??es de passageiros, trabalhar durante as f?rias e "colocar" atestados m?dicos. J? em rela??o ? perspectiva temporal dos motoristas, a sub-escala de presente combinado mostrou uma rela??o positiva com o envolvimento em acidentes de tr?nsito, e a de futuro uma rela??o negativa, em ambos os casos conforme o sentido esperado, ainda que os efeitos n?o tenham sido estatisticamente significativos. As vari?veis preditoras selecionadas indicaram que os acidentes de tr?nsito est?o principalmente associados a fatores situacionais, os quais podem ser evitados atrav?s da melhoria das condi??es de trabalho dos motoristas profissionais e das pol?ticas organizacionais e p?blicas, considerando que os acidentes de tr?nsito devem fazer parte dessas iniciativas nas ?reas de sa?de e seguran?a p?blica
