From 31 January 2018, if you hold a Victorian licence and get caught drink driving interstate, the same rules apply as if the offence occurred in Victoria.
This means that your Victorian licence will get cancelled and you’ll have conditions such as a zero blood alcohol (Z condition) and an interlock (I) condition applied to your licence once it is successfully restored by meeting the necessary legal requirements.
An alcohol interlock must be installed to any vehicle you drive by law.
From December 2017, a blood alcohol reading (BAC) 0.05 to 0.07% will result in immediate licence cancellation for three months, even for a 1st offence. Every drink driver in Victoria would also have interlock devices installed in their car for six months minimum period and will have to complete a new behaviour change program before getting their licence back, beginning 30.04.18
