Under the crackdown, Victoria Police will be able to impound the vehicles of first-time offenders who test positive for drugs and also have a blood alcohol concentration of .10 or higher. First offenders will also face a minimum 12-month licence suspension and fines of up to $4550.

Repeat offenders will face fines of $13,650 to $40,959, depending on their blood-alcohol level and previous convictions. They will also face a minimum two-year licence cancellation – and the prospect of having their cars impounded permanently.
