You have all convinced me on the interlock device, so I have no problem there.
Mr. Marchand, I tend to agree with something that you said—at least I haven't been convinced otherwise—and that a previous witness said. I don't want to rush into increasing the level because of the consequences of a criminal record. They are unintended consequences. When they set up the system, they didn't know they would affect the rest of your life--you couldn't travel, and all sorts of things.
I was quite impressed, actually, with the progress some provinces are making. I thought a lot more of those roadside measures were definitely having a deterrent.
Mr. Murray, I think you said they weren't successful and Mr. Marchand said they were.
Mr. Marchand, could you elaborate on the roadside administrative measures? Is there any proof of the success of those measures?
