Alcohol misuse is a primary cause of road accident deaths and injuries in Australia.
Probationary drivers face a threefold increased risk of road accident injury and are over-represented in alcohol-related crashes.
These factors prompted a campaign for a zero blood alcohol limit for novice drivers.
Purpose of the Study:
To evaluate the impact of zero blood alcohol legislation for learner and probationary drivers in Victoria.
To assess the effectiveness of various drink-driving countermeasures.
Main Methods:
Analysis of compulsory blood alcohol tests on road casualties.
Comparison of pre- and post-legislation data on driver casualties and fatalities.
Evaluation of drink-driving countermeasures including education, penalties, rehabilitation, interlock devices, and legal drinking age.
Main Results:
Evidence of a moderate reduction in alcohol-related road trauma in Victoria since the 1984 zero blood alcohol legislation.
Significant decrease in driver casualties with illegal blood alcohol concentrations (BAC) between 1977 and 1983.
Reduction in driver fatalities with BAC exceeding 0.15 g%.
Conclusions:
Zero blood alcohol legislation for learner and probationary drivers in Victoria has shown a moderate positive impact on reducing alcohol-related road trauma.
Further evaluation of drink-driving countermeasures is warranted to enhance road safety.
