alt Hacker NewsThe "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.
