An interlock device is a breath-testing machine that prevents a car being started if the driver has alcohol in their breath. Under current Victorian law, “disqualified drivers found to be over 0.15, repeat offenders or those under the age of 26 who record 0.07 are required to have the devices fitted”. However, the Government has introduced the Road Safety Amendment Bill 2014 into the Legislative Assembly, which would tighten the rules so that they apply to disqualified drivers over 0.07, first offenders over 0.07, and probationary licence holders over the legal limit. According to the Transport Minister, Terry Mulder, “drink-drivers are responsible for 25 to 30 percent of deaths and 11 percent of serious injuries on our roads, while repeat drink-drivers make up 20 percent. Thirty per cent of drink-drivers involved in fatal crashes are repeat offenders.”
