Results: Should all cars be equipped with an interlock device?

Interlock devices require the driver to blow into the device, which tests blood alcohol level, before being able to start the car. One judge is wondering if all cars are equipped with an interlock device that it will curb the number of impaired driving cases. “I often wonder whether equally substantial savings in the justice system would result if mass-produced Interlock devices were mandatory in all motor vehicles,” says Justice Graham Wakefield.
