BAC Calculator

Thinking before you drive is the best way to prevent being charged with driving while intoxicated. Knowing how much you’ve had to drink and whether or not your abilities are impaired can help you from ever needing the services at the Law Office of Jim Medley.

This tool can be used to help determine how many drinks it really takes to reach the legal limit. This form is only an estimate and is not able to predict with 100 percent accuracy. This calculator should only be used as a guideline, as your own personal circumstances may vary from the results of this reference tool.

Don’t drink and drive – think and drive. Use this calculator to estimate your blood-alcohol level, and don’t let a wrong decision lead to serious and lasting consequences in your life.


If you have any questions on this calculator, please let the firm know by filling out the form on the right side or by calling 713-NOT-A-DWI.
