Illegal consumption of alcohol by a minor in Illinois?

You won't lose your license, you'll probably get a warning, or a fine, or possibly community service. And you did technically refuse the breathalyzer. You might want to tell your parent (whoever is coming with you) to talk to the DA about how you have no record and are usually a good person and blah blah blah. And from now on you might want to learn what "on the down low" means.
