The effect of vehicle roadworthiness on crash incidence and severity

The work presented in this report covers both passenger cars and motorcycles (but not trucks), and comprises: 1. a literature review of Australian and international studies on the effects of vehicle defects, vehicle inspection systems, and ageing of cars; 2. an analysis of the Coroner's Database (Victoria) for the period 1989-1998, to identify defective or unroadworthy vehicles and motorcycles that contributed to crashes. Recommendations are made for further studies, including a comparison of defects found in the NSW and Victorian vehicle fleets.
