An analysis percentage distributions then carried out with respect area zone, severity, type collision, highway. proportionality test used determine significant differences at 5% significance level. Selected characteristics, such proportions single- multi-vehicle crashes, were compared non-work crashes. results indicated predominant regardless highway rear-end crash. also proportion sideswipe same direction significantly higher than involved fatal did
