The penalties vary depending on the reading on your prior driving history and when the offending occurred. If you have relevant prior offences, the mandatory loss periods increase.
Currently, the mandatory minimum licence disqualification for a reading above 0.05 but less than 0.07 is 6 months for a first offence or 12 months for a subsequent offence.
Any subsequent offending within a ten-year limit will have that figure at least doubled.
Higher readings also result in further mandatory licence disqualification limits.
Further, if the reading is BAC 0.10 or more your car can be impounded.
The Magistrate can extend the disqualification period if the driving behaviour was also dangerous.
Once the period of disqualification has elapsed, VicRoads will advise drivers of any further steps or courses they must complete. This includes attending Court and making an application for an alcohol interlock.
