You must take your ID Driver's license photo at the DMV office. 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.
When you apply for your ID Learner's Permit, you will need to bring documents that prove your identity, your lawful presence in the United States, your residency in Idaho and your Social Security Card. If you are under 18, you will also need to submit an application signed by your parent or legal guardian and proof that you are enrolled in school. If you are under 17, you will need to submit a Driver's Training Program Certificate.
