ACCIDENT RISK OF FIRST YEAR DRIVERS: AUTOMATIC V. MANUAL TRANSMISSION

The endorsement of Victorian driver licences for automatic transmission vehicles was removed in July 1984. A thousand first year drivers who had police reported accidents were separated into four groups depending on whether the licence test or the accident involved an automatic or manual car. The accident proportions were then compared with the proportions of distances travelled by drivers in these groups. The resulting relative risk of accident per distance travelled for each of the four groups was estimated and weak evidence was found to indicate a higher accident risk for drivers who took the driving test in an automatic car and subsequently drove a manual car. The extra casualty accidents were spread throughout the first year and hence any difference could extend into the second year of driving. Any extra accidents, however, were not numerous enough to change the overall proportion of 18 year old drivers (necessarily first year drivers) involved in accidents during 1977 to 1988. There was some evidence to suggest that the proportion of first year drivers who take the test in an automatic car and then drive a manual car has increased slightly from 1986 to 1988.
