Illinois DUI Statistics

Posted on in DUI Defense

Illinois drunk driving lawyerDriving under the influence, or DUI is defined as the act of operating a vehicle after the use of alcohol. In Illinois, the legal blood alcohol content, or BAC, is 0.08. If a person has a blood alcohol content above 0.08, then he or she will need to participate in a chemical test typically administered by the police.

2015 DUI Statistics

The blood alcohol content is based on the ratio of alcohol to blood or breath. An individual with less than a BAC of 0.08 may still be convicted of DUI if there is more evidence showing the driver’s impairment when operating a vehicle.

  • In 2015, eight percent of any driver who was pulled over with a BAC of 0.08 and 0.09 failed a chemical test;
  • Thirty-five percent of any driver with a BAC from 0.10 to 0.14 failed a chemical test in the same year;
  • Another 35 percent of any driver with a BAC from 0.15 to 0.14 failed a chemical test;
  • Sixteen percent of any driver with a BAC from 0.20 to 0.24 failed; and
  • Six percent of any driver with a BAC of at least 0.25 failed the chemical test.

How Much Is Too Much?

For a male weighing about 170 pounds, as many as four drinks in one hour can increase his blood alcohol content to 0.08, the legal BAC level. For a female who weighs 137 pounds, three drinks in one hour will increase her blood alcohol content to 0.06, or one fiftieth of a point away from the legal BAC limit.

However, the effect of alcohol is determined by gender, body weight, alcohol tolerance, the amount of food consumed, and the amount of alcohol consumed at the rate absorbed by the body.

The first alcoholic beverage will affect the person’s coordination and judgment, even with a BAC below 0.08. When a person has a BAC between 0.04 and 0.05, he or she increases the risk of being in a car accident and is two times more likely to be involved in a fatal accident than a person who doesn’t drink. When the person’s BAC is 0.08, he or she is 11 times more likely to be killed in a single-vehicle accident than a person who did not drink.
