then a drink containing 1oz of alcohol, or 28 grams, will raise the BAC .03%. If the typical person metabolizes 10 grams of alcohol per hour, then three drinks over an hour will raise the BAC to .08%. So, I stand corrected. Three beers in an hour will get you to .08% if you are the average person. As the article points out, results can vary widely depending on the individual.
It doesn't change the fact that a .08% BAC limit does not take into account individual differences and that there are people with 0% BAC on the road that are more dangerous than many with .08% BAC.
Edit: also, many states (CO being one) have a limit of .05 BAC as legally impaired which carries nearly the same penalty as DUI.
You READ correctly, but a beer does not contain 28 grams of ethanol. Depending on the brand, it has around 12-13 grams only. Ice beers have slightly more, lite beers have slightly less...but NO american beer has 28 grams of ethanol.
