This study uses Victorian casualty crash data for 1983-1993 inclusive to investigate the effects of zero blood alcohol (BAC) laws on the casualty accident involvement of Victorian probationary (provisional) licensed drivers. Multivariate, multiplicative time series models are used to compare the effects of the one, two and three year zero BAC restrictions which were progressively applied to Victorian probationary drivers since 1984. Covariates such as alcohol sales, unemployment rate, amount of random breath testing and anti-drink driving advertising are also taken into account. While results show some evidence of effect for zero BAC restrictions, they also show differences in the magnitude of effect related to factors such as the duration of zero BAC restriction, sex of driver and location (i.e. metropolitan versus country).
