Blood Alcohol Level Chart: Are You Too Drunk to Legally Drive?



Use the blood alcohol level chart to estimate how many drinks it takes to put your blood alcohol concentration (BAC) above the legal limit.

In every state, it’s illegal to drive with a blood alcohol concentration (BAC) of .08% or more. 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 equates to a given BAC level. The chart below, however, gives BAC estimates that correspond to number drinks consumed and body weight. (Also, check out our BAC calculator.)

USING THE CHART

  • One drink = 1.5 ounces of hard liquor, 12 ounces of beer, or five ounces of wine.
  • Blue = Impaired driver.
  • Red = BAC of .08% or greater, a “per se” DUI in every state.

Disclaimer

The BAC values in the above chart are only estimates. You shouldn’t rely on the accuracy of these estimates. The chart doesn’t account for all the factors that can affect BAC levels. If you’ve been drinking, it’s always best to let someone else drive.
