The length of time that you will be required to have an interlock device installed in your vehicle can vary depending on your individual circumstances and the specific requirements of your interlock program. In New South Wales (NSW), interlock periods typically range from 12 to 48 months.
To determine the specific length of time that you will be required to have the interlock device installed, you should refer to the paperwork provided by the Transport for New South Wales (TfNSW) when you applied for your interlock program. This paperwork will outline the terms of your interlock program, including the length of time that you are required to have the device installed, as well as any other program requirements that you must meet.
It is important to remember that the interlock device is a mandatory requirement for individuals who have been convicted of a drink driving offence, and compliance with all program requirements is necessary to successfully complete the program and regain your driving privileges. Failure to comply with program requirements, including the installation and use of the interlock device, can result in additional penalties, program extensions, or the revocation of your driving privileges.
