The Intoximeters Inc. "Drink Wheel" is a form that you can fill out. Upon completion it will instantly compute your estimated blood/breath alcohol concentration ("BAC") based on the information that you have provided and return that estimate to you. It is presented as a public service by Intoximeters to Intoximeters web site visitors. Its primary purpose is to provide useful information about the responsible use of alcohol.
It is called the "Drink Wheel" because it is based on various paper and cardboard BAC calculators that are given out in alcohol awareness programs, some of which are in the form of a wheel that you can spin around to calculate your estimated BAC based on what and how much you have had to drink.
It would be extremely foolish for us to pretend that our "Drink Wheel" can tell you what your BAC actually is. A person's actual BAC is dependent on many complex factors, including their physical condition (body composition, health etc...) and what they have recently ingested (including food, water, medications and other drugs).
The results that are generated are rough estimates of an average healthy person's BAC assuming typical beverage sizes, recipes and alcohol content. The BAC estimates generated by the Drink Wheel should not be used to infer anyone's fitness to work, drive or perform any other task or duty.
