A disproportionate number of road fatalities are 17-19 year olds. One way to reduce this is through Road Safety Education (RSE} in schools. This study reports Western Australian teachers' perspectives of delivering RSE to Year 10 $tudents using a multiple case study research design. The cross,;case·analysis identified seven themes influencing teachers' delivery of RSE: authenticity, responsible road use, timetable constraints, engagement, passion, pastoral care and standardised program. The study recommends linking RSE to authentic experiences, utilising best practice RSE, increasing awareness of existing RSE programs, linking RSE to mental health programs and including RSE in the Wei;tem Australian Curriculum.
