Do you know how many drinks you can have before you're in danger of getting a drunken driving violation?
When police pull drivers over for suspected drunken driving, officers ask them to perform field sobriety tests and to take a breath test to measure Blood Alcohol Content.
A BAC test measures the percentage of alcohol present in a person's bloodstream. Illinois' legal limit is 0.08.
However, a person can still be charged even if their BAC is under 0.08 and prosecutors can prove driving impairment.
According to the Virginia Tech Alcohol Abuse Prevention website, every 40 minutes, 0.01 percent of alcohol leaves your system.
So, check out these attached charts before you head out on New Year's Eve, and remember, please don't drink and drive!
Editor's note: This story has been updated to say that a person who is driving with a alcohol level below 0.08 can still be charged with driving under the influence.
