Is that right? (The beer bit I mean…) – DUI is based on blood alcohol level, if all the alcohol in a pint were to enter your blood almost simultaneously, would that be enough to push you over the limit?
(Assuming normal strength beer, adult male, etc.)
1 pint of beer @ 5% = 28.4 mL of pure ethanol. Ethanol has a density of 0.789 g/mL so this is 22.4g
Assume adult male, with 5L of blood.
So if all that alcohol could instantly get into the blood and none of it is metabolized yet then this would equate to 448 mg/100mL.
The UK driving limit is 80 mg in 100 mL of blood. However of course a significant proportion of the alcohol simply passes straight through.
