You must take your OH Driver's license at the BMV office when you go in to take your exam. When you take your photo, you should make sure that you wear what you would wear normally. It's extremely important that your face is clearly shown and recognizable. Look straight at the camera and do not smile, as a resting face is easier to identify.
If you are under 18, your legal guardian or parent must accompany you. Your legal guardian or parent will need to co-sign your permit packet. In some instances, if your legal guardian or parent is not able to accompany, a responsible license driver may be able to sign for you. You should contact your local OH BMV for more information about this or visit this website: www.bmv.ohio.gov.
