Well, not quite, because my first question to you was about an officer in the normal course of his duties seeing a car, having no reason to believe that the driver is impaired, but having a legal reason—enforcement of the provincial highway safety code, for instance, if the tail light is off—to stop the driver and ask him, “Did you know your tail light is off? I'm going to give you a 48-hour warning to go and get it fixed”, for instance. Or, “Your muffler has partially detached”. It's in the course of doing this that the officer gains some suspicion that possibly this is a driver who is impaired. And then all of the other steps follow.
