[MCU] Captain America has been drinking. Will a breathalyzer or blood test pick that up? Is he legally considered drunk?

Hypothetical here: If Captain America, for whatever reason, goes to a bar and puts away three bottles of whisky in under an hour, then gets on his motorbike, starts riding home, and gets pulled over by the local sheriff's department, will he register as drunk on a breath or blood test?

We know he can't get drunk, as such - at least on mortal alcohol - but will the presence of the alcohol in his system register?

And, as a follow-up question, if he *doesn't* register as drunk on conventional testing, but thirty deeply unpatriotic bar patrons all bear witness to the fact that he drank all that whisky, could he be prosecuted for DUI according to the letter of the law?

The reason he can't get drunk is that his body's metabolic rate is so high that the alcohol leaves his bloodstream before the effects can occur. It's not that he just powers through his drunkenness, there just isn't any in his system. So a breathalyer test would show the same results as a sober person and since the legal limit is based on the amount of alcohol in the blood and not the amount drunk, he'd be fine.
