Offical DMV BAC Tables
- This guide below shows, for a given individual, the DMV’s best guess as to what the breath test results would be for a given amount of drinking. There are so many variables in the formula used to calculate breath test results based upon weight and number of drinks consumed that it has limited utility as a way to precisely determine an individual’s breath alcohol concentration.
- One drink=1 ounce of 80 proof spirits; 3 ounce glass of wine; or 8 ounce glass of 5% beer.
