This study suggests that lowering the legal BAC limit is effective in decreasing road traffic injuries and fatalities. After the implementation of RBT and the 0.05 BAC law, fatal collisions was reduced by 18% in Queensland and 8% in NSW. The results indicate that administrative licence suspension, zero tolerance laws and graduated licensing could help in decreasing alcohol-related injuries and deaths.
