The research on the ignition interlock is very strong, especially when it is on the vehicle. I really believe that the ignition interlock problem should be under provincial jurisdiction. That's where it belongs, and that's where the most innovation could be done. That's where the greatest relationship between the person on the interlock and the authorities could be.
One of the things that Canada has so far failed to do in its interlock programming is make it performance based. Right now the interlock is put on the vehicle, and usually it's taken off after a given period of time, largely following what the Criminal Code allows. For a first-time offender, it's three months' hard suspension, nine months on the interlock. At month 12, regardless of performance--even though the person's showing signs that they'll reoffend or return to old habits--the interlock is removed from the vehicle.
We'd like to see the federal Criminal Code amended so that we don't have those long hard suspension periods, which cause inconvenience to the province and also teach convicted drinking drivers how to drive suspended and not get caught. So that's very important.
Once we have that, the province needs to make it mandatory and performance based, and I think you'll see participation rates go up, and you'll also see the number of impaired driving deaths go down slightly. You have to remember that it's not going to have the wide ramifications of a lower BAC or random breath testing, because it's only dealing with the convicted market. Those other factors deal with the whole population that might drink and drive.
