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.

The "legal limit" is terribly misunderstood, but 0.08% is just legal threshold where the state doesn't need to prove impairment and the offense is upgraded to an automatic criminal DUI. A driver in an accident with a BAC of 0.03% could still be charged with a DUI if impairment can be proven but most prosecutors' offices have more important things to work on.

Sure, I don't disagree.

It's also terribly misunderstood by pedants since you can be charged with a DUI with a 0.00 BAC by doing drugs. The point isn't that it's a definitive line in the sand between impairment and not, but if people are trusted to drive a car (generally or broadly speaking, not pedantically speaking), being above or below said limit is a reasonable litmus test for "visibly/obviously impaired" or not.
