The linked traffic offence and crash records of 73 percent of an original cohort of 61,000 high school students (Grade 10) recruited in 1988 and 1989 were studied to determine the prevalence of prior offences among 1063 drivers involved in a serious (fatal or hospitalisation) crash ("serious crash class") and 5543 drivers involved in a less serious crash ("minor crash class"), by year of first (index) crash. Offences were categorized as drink driving, speeding, dangerous driving and other. Relative risks of a subsequent crash and differences in mean numbers of other offences were computed for serious versus minor crashes in both sexes and for serious and minor crashes versus no crashes in males, adjusting for year of index crash. An effort was made to account for possible over-statement of the size of the group with no recorded crashes ("null crash class").
