That's why you park in town until the weather changes.

That being said, I know "in season" BC requires all vehicles to have chains (including the trailer drag chains), I simply don't recall if Alberta does also.

Montana didn't when I lived there (I doubt they do now). But when Montana goes to "chains required", they mean it.
