you don't get your liscense until your 16 and if your 16 or 17 then you wont have your learners permit anymore
Check the driving manual in your state. It should say what will happen. Some states will charge a fine. Some states will arrest you. Some will impound your car or make your parents come get you and the car. Some states will take away your learner's permit and not allow you to get it back until 18 or 21. You may get lucky and get out with a small fine, or you may have serious problems. Don't risk it.
