What blood alcohol level is drunk...
Use the blood alcohol level chart to get an idea of how many drinks it takes to put your blood alcohol concentration (BAC) above the legal limit.
In every state, it's illegal—a "per se" DUI—to drive with a blood alcohol concentration (BAC) of .08% or more.
Blood alcohol level normal range
(The BAC limit can be even lower for certain motorists, like commercial vehicle drivers and drivers younger than 21.) But everyone absorbs and metabolizes alcohol at different rates, and there are lots of factors that affect BAC.
So there's no exact formula for determining how many drinks equate to a given BAC level. Plus, you can be convicted of DUI for driving "impaired" (by alcohol or drugs) even if you were under the BAC limit.
The chart below gives BAC estimates that correspond to number of drinks consumed and body weight.
