Different types of drinks do not affect you differently. It is the amount of alcohol you consume, not whether it is in beer, wine or wine cooler, or liquor, that raises your BAC and lowers your driving ability. These drinks contain about the same amount of alcohol - 1½ ounces of liquor, 5 ounces of wine, 12 ounces of beer, and 12 ounces of wine cooler. None is "safer to drink" than the others.

For a male weighing 150 pounds, each one of these drinks would contain enough alcohol to increase his BAC by about .02 percent. On average, it takes the human body about one hour to dispose of that much alcohol. However, studies suggest that a woman's body may process and remove alcohol from the blood more slowly than a man's. This may result in a higher BAC over a longer period of time.

1 beer = .2 on the test. but .8 is legal evidence of intoxication. So just have less than 4 beers and you're fine. This is for NY state however..

Yea, I read the drivers manuel
