The results of an independent t test showed a statistically
significant difference between accident-involved and
accident-free motorcyclists with respect to ordinary and
aggressive driving-violation behaviours, and the selection
of driving- and belief-related causes. Accident-involved
motorcyclists showed higher mean scores for both ordinary and aggressive driving-violation behaviours, and also
for belief-related causes, but lower scores for drivingrelated causes, compared to their accident-free counterparts (Table 3). These findings indicate that the accidentinvolved motorcyclists committed certain driving violations more often. In addition, they considered drivingrelated causes of accidents to be less important and
belief-related causes more important than motorcyclists
without an active accident history.
