The system which has been in use in many countries for many years will not allow a vehicle to start if the driver fails a breath test. Unfortunately it doesn't stop another person from blowing into the device to start the car.
The installation of the system will cost around $2,000 and we have to wonder if it can be installed in new vehicles with smart-key start button ignition systems.
The trials of the system had began as early as 2001 and now, 9 year later, the system is finally being put to use. Queensland's Transport Minister Rachel Nolan says the government was being cautious "The implementation of interlocks is a complex undertaking," she said.
The mandatory interlock rules will be in full affect by the end of the year.
