Psychological strain due to the work environment is common, especially in those occupations which involve working in critical situations. Working as a police officer seems to increase the risk of psychological problems such as symptoms of stress and post traumatic stress disorders. The aim of this study was to describe male police officers' experiences of traumatic situations when caring for victims of traffic accidents, and to reflect the results through the perspective of gender theories. Nine police officers were asked to narrate and reflect upon their experiences in taking care of people who had been severely injured in traffic accidents. The interviews were analysed with qualitative content analysis. The findings are presented in three themes: "being secure with the support system", "being confident about prior successful actions, and "being burdened with uncertainty". The officers' descriptions showed that most of them had strategies that they used when they were first responders, developed on the basis of their own knowledge and actions and the support systems in their organization which enabled them to act in traumatic situations. When support systems, knowledge, and actions were insufficient, they sometimes felt insecure and "burdened with uncertainty". In this male-dominated context, there was a risk that the officers may not talk enough about traumatic situations, thus influencing their ability to cope successfully.
