Drinking and Driving is a terribly irresponsible thing to do. Most states have a
legal limit of 0.08 or 0.10 Blood Alcohol Level. This is the maximum level your
BAC can be before you face penalties (Like losing your license and ooodles of
cash, not to mention getting jail time.) There is a formula that you can use to
determine your BAC. This formula requires four factors.

This formula is not perfect, nor should it be used to gauge a life or death decision
to drive but you can experiment with a few variables to determine acceptable
levels to stay within while you are drinking.
