You are currently viewing Florida Blood Alcohol Level Calculator

In Florida it is unlawful to drive or be in actual physical control of a motor vehicle if your blood alcohol is above .08. Below is a calculator which is designed to predict your blood alcohol level at the time of driving.  The calculator is based upon a theory called Widmark’s Formula, which is used in the defense of DUI cases to argue the possibility of a lower blood alcohol level at the time of driving, and to raise doubts as to the reliability of the breath testing instrument.

The factors in making the blood alcohol level determination include the sex and weight of the driver, the type of alcohol consumed, and the period of time in which the alcohol is consumed. Each person metabolizes alcohol at a different rate, so a calculator such as this can only be used as an estimate.
