Blood Alcohol Content

Blood alcohol content (BAC) is the amount of alcohol in your bloodstream. This can be measured by blood, breath or urine. When you consume alcoholic drinks, the alcohol is absorbed into your blood stream. In Wisconsin, you are considered to be "per se" intoxicated if your BAC is .08 or higher and no additional proof of driving impairment is necessary for the officer to arrest and charge the driver with a drunk driving offense. This measurement means that your blood contains ten/one-hundredths percent of alcohol. Most people associate this with "drunk driving" but it really refers to impaired driving, since you may not feel drunk at all, and yet still be impaired in your ability to drive a car safely.

In Wisconsin, a police officer may charge a person under the age of 21 years with a drunk driving offense if they were operating a vehicle with only a detectable trace of alcohol. If the police officer suspects that a driver is impaired, they may require a person to take a breathalyzer or other test to determine their BAC. Refusal to take a test may result in additional charges and fines or suspension of your driving license. It is important to note that an individual still may be charged with a drunk driving offense without taking a BAC test or if your test results were lower than <.08. Additional evidence that may be used against you in a drunk driving matter include: the smell of intoxicants on your breath, your conduct and officers observations at the time of the stop or arrest, slurred speech, and impaired motor movements, as a short list of examples.

What factors can affect your BAC level?

Several factors can affect your BAC, not simply the amount of alcohol you drink. These factors can include:

  • How fast you drink. The faster you drink, the higher your BAC will be.
  • Body size. Large body sized individuals people tend to have lower BACs than smaller body sized individuals, even with the same amount of alcohol.
  • Whether you have food in your stomach. When there is food in your stomach, alcohol is absorbed by the blood stream more slowly.
  • Type of mixer used. Water and fruit juices mixed with alcohol may slow the absorption process, while carbonated beverages can speed it up.
  • Women generally have higher alcohol concentrations than men, even when drinking the same amount of alcohol because their bodies are made up differently.
