Is USA the outliner here? In (most of) canada 0.05 will get your license suspended (but you dont go to jail unless its 0.08).

Australia, scotland and france are also 0.05.

There are quite a few countries where the limit is less than that.

Maybe? Virtually everywhere in the US is 0.08. I don't think it's a good idea for physical pentesters to drink anything before a gig, for whatever that's worth, so hopefully we're just shooting the shit about different countries rules.
