Mandatory Alcohol Interlock Program

Tasmania's Mandatory Alcohol Interlock Program (MAIP) applies to people who are convicted of drink driving offences after serving their disqualification.

You will be required to participate in the program if you are convicted of any of the following offences:

  • a drink driving offence recording a BAC of 0.15 or more
  • two or more drink driving offences in a five year period
  • driving under the influence of liquor
  • failing to provide a breath/blood specimen for analysis
  • An alcohol interlock is a breath testing device connected to a vehicle’s ignition. Each time you drive the vehicle you must take a breath test and if a BAC is registered of .02% or above the vehicle will not start. Any I condition licence holder must have a .00% BAC at all times whilst driving.

Alcohol interlocks aim to protect the general public by ensuring program participants can only drive with a zero Blood Alcohol Concentration (BAC).

To legally drive, program participants must fit an alcohol interlock from an approved supplier to any vehicles they drive.

The cost of participating in the program is approximately $3,000-$3,500. Participants will be required to pay all costs relating to the program. However, a fee waiver (covering installation, administrative, schedule servicing and removal costs) is available for individuals who committed an offence that triggered the requirement to install an Interlock system prior to 31 July 2013. See Fee Waiver for more details.
