The legal limit is 0.04% or 40 mg/dL for commercial truck drivers.

So his BAC was 0.28%, which is pretty dang loaded!

Wow. I’m surprised they even have a limit. I woulda guessed it was zero tollerance. After all, this is their job and they are on the clock. No one else is allowed to show up for work buzzed.

I think the 0.04% has been the standard set by US DOT for any commercial transportation. Other cases are more stringent. I have heard that some parts of the North Slope (Alaska) have effectively zero tolerance on alcohol.
