The IRMRC Crash Investigation Study (ICIS) will involve detailed crash investigation of a random selection of approximately 100 police-reported injury crashes in the Sydney region and selected rural areas of NSW, in order to provide information about the causes, patient journey and cost to the community of a sample of severe road trauma cases in NSW. The objective is to gain a greater understanding of the:

• true burden and cost of major road crashes resulting in injuries; and
• mechanisms producing the injuries which will enable the causes to be addressed by road authorities and partner agencies.
