The Alcohol Interlock Functional and Technical Specification  was developed by TCA in response to the growing need for stronger assurance in the use of alcohol interlocks for government-led safety programs.

The Specification is currently used in New South Wales for the Mandatory Alcohol Interlock Program (MAIP) - which commenced operation in early 2015 - and will be used in Western Australia for the Alcohol Interlock Program (AIP) , which is expected to become operational and available by the end of 2016.

The Specification was developed to establish the minimum functional and technical requirements for alcohol interlocks – which avoids the need for alcohol interlock suppliers to meet bespoke requirements between jurisdictions – while allowing specific policy and operational needs by different regulators to be accommodated.
