ACCIDENT EVALUATION OF CHANGE IN TRUCK SPEED LIMIT FROM 80 TO 90 KMH

On 1 January 1987, the maximum speed limit for heavy vehicles was raised from 80 km to 90 km per hour; the speed limits for other vehicles remained the same. This study sets out to see if there was any significant change in Victoria in the frequency of rigid and articulated truck accidents against accidents involving only cars and car types, following the speed limit change. Due to data availability only serious casualty accidents were studied. These results were assimilated with the findings of the national speed survey conducted by the Federal office of road safety. In effect, there was no significant change in overall speeds, even though the speed limits were increased. This reflects the change in the number of accidents for car and rigid trucks, which was also non significant. For articulated trucks, even though the mean free speeds increased significantly, there was no significant increase in the number of accidents (a).
