Blood Alcohol Levels

BAC — Blood Alcohol Concentration — Blood Alcohol Content

Having a high blood alcohol level can lead to serious consequences if you are caught behind the wheel. At the law offices of Michael T. Norris, Ltd. and John W. Callahan, Ltd., many of our clients are people who were accused of driving with a BAC of .08 or more. Located in DuPage County, we defend them in Illinois courts — helping them avoid jail time, community service, fines and court costs after a DUI arrest.

Illegal BAC limits in Illinois are different depending on certain factors, like the age of the driver and whether or not he was operating a commercial vehicle:

  • Drivers under age 21 face a zero tolerance policy — .00
  • School bus drivers face a zero tolerance policy — .00
  • Commercial driver's license holders — .04
  • Drivers over age 21 — .08

At the law offices of Michael T. Norris, Ltd. and John W. Callahan, Ltd., we represent clients of all types facing drunk driving allegations. Our clients include professionals, blue collar workers, students and professional drivers with CDLs.

While many of our clients' BACs register at just over the legal limit, some are substantially more. If you blow a .16 or more BAC in Illinois, you may face more serious penalties than with a lower BAC. These penalties include extra jail time and community service.

What Your Lawyer Knows About Breathalyzer Test Results

Breathalyzer tests are not always accurate. In fact, they are notoriously wrong. Many lawyers — like the criminal defense attorneys at Michael T. Norris, Ltd. and John W. Callahan, Ltd., examine the chemical test results closely and have the tests thrown out if they are not correct.

We look to see if the Breathalyzer was calibrated properly, making sure the settings for the computer system in the machine are correct. We also look at when the test was administered. The level of alcohol in your blood peaks hours after you stop drinking, so waiting too long after leaving the bar can actually cause your BAC to rise more than it otherwise would.
