Agree w Dr. Woods.
Level- Currently in the US it is 0.
08 % (in all states). In countries like Mali, Pakistan, United Arab Emirates (UAE) or Saudi Arabia it is 0.00 by Muslim Law. The only countries I could find with a higher Blood alcohol content % were Cyprus at 0.09 (but it is changing to 0.05) & Swaziland. You may have impairment at lower than 0.08.
