This report presents an overview of results tabled in other reports in this series which separately analysed Australian and USA mass crash databases. The focus was on identifying differences between the crash patterns of young and mature car drivers which occur consistently across databases, as well as consistent differences between daytime and night-time crash patterns. Results showed that day/night differences were often large, and usually of similar magnitude for both young and mature drivers. Higher young driver compared to mature driver involvement was shown for single vehicle crashes, crashes occurring on curves or slopes, travelling above the speed limit or at excessive speed, and crashes where `loss of control' was identified as a causal factor.
