Alcohol is the leading contributing factor in approximately 30% of fatal crashes across Australia. As we head into 2026, state governments have further tightened regulations, particularly regarding mandatory Alcohol Interlock Programs and immediate licence suspensions.
In Australia, the legal Blood Alcohol Concentration (BAC) limit for full licence holders is 0.05. A Zero BAC limit applies to Learner, Provisional (P1/P2), and heavy vehicle drivers.
