A good Rule of thumb is that one drink is metabolized to the point
of elimination from the blood stream each hour. Therefore, typically,
if you have one drink, waiting one hour before driving is a good
idea. Other factors influence and can increase or decrease one's
BAC such as fatigue, having eaten, and the type of drink it is,
so the best way to avoid a DWI is to avoid driving after drinking
anything at all.
