Transport Accident Commission Victoria’s holiday enforcement spot lands on a familiar moment: someone says “I’ll drive”, someone asks “Are you sure?”, and the answer is the classic risky logic, “I’ve only had a couple of beers.” The campaign message is blunt, police will use multiple enforcement options over the holidays, from booze bus checkpoints to mobile units equipped to breath test, plus unmarked cars and motorcycle units. The line that ties it together is simple: “How your holiday ends is your choice.”

The TAC backs that message with the why. Around 1 in 5 drivers killed on Victorian roads have a blood alcohol concentration (BAC) of 0.05 or higher, and alcohol affects perception, vision, concentration, reaction time, and it can cause drowsiness. The campaign also leans into a point people tend to underestimate: alcohol can affect you differently from one day to the next, so there is never a “safe amount” when you are planning to drive.

They also spell out what different BAC ranges can do to driving performance, from reduced ability to judge distances and increased risk-taking at 0.02 to 0.05, to slower reactions and impaired concentration at 0.05 to 0.08 (with 0.08 described as five times more likely to be involved in a crash), and impaired perception plus overconfidence at 0.08 to 0.12 (up to 10 times more likely to have an accident). On the policy side, TAC highlights measures like alcohol interlock devices for drink drivers when relicensed (citing a Victorian study that found a 79% reduction in repeat offending for those required to fit an interlock), trialling new technologies to prevent serious injuries and deaths, and exploring tougher requirements for repeat offenders, including a zero BAC limit for life.
