<![CDATA[First aid is an immediate and temporary intervention provided at the scene before advanced medical assistance becomes available. Traffic police, as trained lay responders, play a critical role in emergency situations, particularly in traffic accidents. This study aimed to identify factors associated with traffic police officers’ knowledge of providing first aid to accident victims. A quantitative method with a descriptive-analytic design and a cross-sectional approach was employed. The sample consisted of 50 traffic police officers from the Pekanbaru Police Department, selected through consecutive sampling. Data were collected using a structured questionnaire assessing knowledge and attitudes toward first aid. The results showed that the majority of respondents were aged 26–39 years (82.0%) and had higher education (52.0%). Most had not received additional training (78.0%), and 60.0% had provided assistance to accident victims in the past two years. A total of 58.0% of respondents demonstrated good knowledge. The most significant factors influencing knowledge were additional training (p=0.016; OR=10.526) and higher educational attainment (p=0.025; OR=3.800). These findings underscore the importance of supplemental training and the integration of first aid content into formal police education. Practice-based and simulation-based training programs are recommended as effective strategies to enhance practical skills and strengthen the role of police officers as lay first responders in emergency situations.]]>
