— How it Works? —
An interlock is a breathalyzer that is hard wired into a motor vehicle.
An interlock tests for the presence of alcohol on the breath.
A driver must take a breath sample in order to start the car.
If the sample is above the preset limit the car won’t start.
A driver is required to take periodic retreats during their drive.
An interlock can only prevent a car from starting it cannot shut off an engine that is already running.
