Yes, but my question is not when you're doing a systematic roadside check operation. We see that a lot, like before the Christmas holidays. I'm talking about when the SQ or the QPP are patrolling highway 40—that's normal—and they see a car with a broken tail light. Correctly and legally, they intercept the car and ask for the driver's permit and registration for the car in order to issue a citation, a warning, whatever, and at some point they decide to conduct a roadside sobriety test.
What would give rise to sufficient suspicion on the part of the officer to legally permit him to do that?
