Interlock plan for all Vic drink-drivers A PLAN to install alcohol-interlock devices on the cars of all drink-drivers in Victoria will save lives, the state's deputy premier says. Drink-drivers across the state will be ordered to fit the devices to their vehicles at their own cost under laws being drafted by the state government. A vehicle with an interlock will not start unless the driver passes a breath test. The interlock can cost more than $1000, depending on how long the device is installed. Deputy Premier and Police Minister Peter Ryan says drink-driving causes 25 to 30 per cent of deaths on the state's roads. "This will also bring about a strong cultural change and it will save lives," Mr Ryan told Fairfax Radio on Monday. People get killed on our roads not because of accidents - it happens because people make poor choices and the issue here is do not drink and drive. Mr Ryan said the reforms would apply in all cases, except where exceptional circumstances are proven in the courts. The magistrate will decide the length of time the devices should be fitted. Mr Ryan said the public wants a tougher approach to drink-driving and these reforms strike a good balance. The state government believes the crackdown can catch about 17,000 motorists a year who blow .05 or more. At the moment, only repeat offenders, drivers who blow .15 or more and those aged under 26 who blow .07 or more have interlocks fitted. VicRoads supports the proposed reforms.
